Z-Stack 3 on CC2538 adventures

[antst]

Me and @kirovilya were working recently on the CC2538 + Z-Stack 3 solution from hardware/firmware side.

As result, I am now testing coordinator on CC2538+CC2592 (ie 20dBm amplifier) on my test mesh with 22 devices. It was never stable enough with CC2530/2531 and first impression is that CC2538 is much better. But it is first day of testing only.

While it is in test, we will start adding here instructions etc.

[lolorc]

what kind of board are you working with ?
I have one from aliexpress https://www.aliexpress.com/item/32791437711.html?spm=a2g0s.9042311.0.0.5ca94c4d6q47wx but I'm yet to do anything with it.

[kirovilya]

@lolorc I have the same https://ru.aliexpress.com/item/32879578178.html

[kirovilya]

What you should know::

1. How to flash the module (flasher and connection)
2. How to connect the module to the serial port
3. How to prepare ZNP-firmware for flash (cc2592 patch and special directive for connecting to the USB or UART)

[lolorc]

1,2,3 aren't a big deal, It's just about spare time I have left at the moment. :-)

[antst]

Here I attach minimal schematics for 2538. Power regulator (surrounded by dashed line) can be replaced by cheap simple module, there are plenty of them around, just look for "AMS1117-3.3 LDO 800MA" (for example here) . CC2538 module of my choice can be purchased on aliexpress here

If you choose another module, then you need to figure out pinout yourself. Practically, there are two most common modules, the one I used (which has PCB antenna and IPX connector for external one) and another one which has only IPX. IMPORTANT: Pinout of those modules is different.

As for programming, you will need J-link and I included pinout for that for typical 20-pin interface.
You can use native segger application for flashing or you can flash from IAR.
Alternatively, if you don't have j-link, you can flash via any SBC with GPIO (Raspberry Pi for example) by using OpenOCD.

Firmware can be found at https://github.com/antst/CC2538-ZNP-Coordinator-firmware

PS: Just in case, I run it for a week and very happy. 27 devices, no lags, no lost devices, no crashes, minimal latency (I also added some modification to Z2M to reduce delay between commands from default 250ms to 50ms, now coordinator can handle it), and it works like a charm :)

PPS: We are in the process of designing PCB for this coordinator, it will include some additional stuff, which can be handy. Possibly, including watchdog, if I will get it working.
Board will be quite universal and flexible, most of stuff will come as optional, and if you don't need, you just don't solder it :)

PPPS: You can try to neglect C4 and C4 and remove R1 and R2 (replacing them simply with wire) (so only R3 from USB schematics will remain), it might work in most of cases, but no guarantee, if it doesn't work for you, then use full schematics. R3 is flexible, might be anything in range 1-2K.

[antst]

Firmware is based on Z-Stack 3.0.2.

[fluppie]

Nice! I want one :).

[rstein]

Great progress, thank you for your effort!
Can you already recommend a specific external antenna (gain)?

[antst]

Great progress, thank you for your effort!
Can you already recommend a specific external antenna (gain)?

Not really. But keep in mind, there is already amplifier and this module has transmission power of 20dBm.

[antst]

And antenna on this stick is optional. Module has PCB antenna also, it is configurable (via re-solder of resistor) to use PCB antenna or external one/

[matlab22]

teaser )

How do you connect the sma? Ipex coax cable? Where is the ldo on your pcb? Back side?

[antst]

Yep, for use with external antenna it is supposed to be connected by IPX coax, and resolver resistor on module. Didn't try it yet. LDO is on back side, yep. Device is not fully assembled. I am still waiting for some parts.

[9600]

This sounds pretty great. Would the firmware need modifying for use with:

http://www.ti.com/tool/CC2538-CC2592EMK

?

Are the sources in a repo somewhere? And do you have details of the zigbee2mqtt changes you made?

[drbios]

hello
what about this board??

https://es.aliexpress.com/item/CC2538-CC2592-Placa-de-desarrollo-Contiki-6-aprendizaje-bajo/32836343416.html?spm=a2g0o.cart.0.0.4bd03c00mo2Xru

[marsjan155]

@Aniol83
IMHO the marked inductors are wrong:

here is similar antenna track with proper inductors:

[hallard]

My fault looking reference design also the capacitor indeed I talk about is part of the matching antenna/lna circuit it's probably C106 or C107, and as suggested @marsjan155 1 and 2 may not correct.

[co-Palko]

I would not advise using this board, firstly, as already written - in the RF circuit, the wrong inductances are installed (this can only be checked by replacing them with the correct ones), and secondly, the exploded capacitor shows that the manufacturer did not bother with the correct selection of components. In the third in the amplifier bias circuit, there are no filtering capacitors C106-108. All of this together can give bad results.
The capacitor that you have is faulty belongs to the power circuits C131-C151.

[Kosygor]

I received this adapter model and I have a problem. I uploaded by jtag: JH_2538_2592_ZNP_UART_20201010.hex. I connect via micro USB to the Zigbee2MQTT server; Configuration.yaml file configuration

@Aniol83 Can you check if this board is sending anything with this firmware when not connected to Z2M?
I am about to make ser2net but everything that I am doing does not work.
Did You made some pull ups or pulldown on board or jus connected GND, VCC, RT, TX ?

[p2baron]

Did you managed to fix this? I'm having identical issues with the same board.

[jeroenvdwaal]

Hi, I like to join the conversation. I like to switch from a CC2531 to a CC2538 + CC2591, to improve the signal range. The zigbee2mqtt adapter section describes the CC2538 + CC2591 with 'Very good range, ~800m line of sight, sensitivity is due to the onboard CC2592 Power Amplifier (20db)'

The range is very limited to the board I have received. I did some testing, by pairing a single device, a Hue bulb, nothing else. Reported the hue bulb signal strength while moving away from the antenna. Close to the antenna, the signal is 120+, a meter away, it drops to 90 and 10 meters away, the signal is 25 (line of sight). Moving to another floor, the signal drops to 2.

I tried to keep away from interfering devices, like the production CC2531 and wifi access points. The CC2531 is configured for channel 11 and the CC2538 running on channel 25.

Repeated the test with another device, giving similar results.

This doesn't feel right. If you watch this Texas Instruments demo on youtube, they show data transfer over a 3,5 km distance.

Is it possible that someone repeats this test, and report back to this topic?

[hallard]

I received mine last week, the first thing I noticed is that the modules are by default configured for UFL connexion (so external antenna), worth mentioning that because as @frank-f wrote, never use without antenna connected. But from my point of view creating a board with PCB antenna but not connected by default is a no sense ;)

[frank-f]

On mine it was the same and since my U.FL cables had not arrived yet, I had at first just bridged the connection to the PCB antenna, leaving the resistor (?) where it was, but the resulting range was absolutely terrible (somewhere around 20 centimeters or so). I did not check if it's better with the resistor removed, but maybe that's why they go for U.FL by default?

[glsf91]

I believe, that linkquality is not a reliable metric to determine the signal strength between two devices. In my setup the reported linkquality varies greatly throughout the day. I have multiple devices that sometimes report 0 and sometimes 140, but even a 0 does not result in commands sent to the device being lost. This was the same with my CC2531. With the latter I did however have severe problems with devices leaving and reannouncing themself to the network, which is why I went to the CC2538.

Not directly, but it has a relation to it.

See https://www.ti.com/lit/ug/swru191f/swru191f.pdf in 23.10.4 Link Quality Indication:

The link quality indication (LQI) is a measurement of the strength and/or quality of the received frame as defined by the IEEE 802.15.4 standard [1]. The LQI value is required by the IEEE 802.15.4 standard [1] to be limited to the range 0 through 255, with at least eight unique values. The radio does not provide an LQI value directly, but reports several measurements that can be used by the microcontroller to calculate an LQI value.
The RSSI value can be used by the MAC software to calculate the LQI value. This approach has the disadvantage that, for example, a narrowband interferer inside the channel bandwidth can increase the RSSI and thus the LQI value, although the true link quality actually decreases. The radio therefore also provides an average correlation value for each incoming frame, based on the first eight symbols following the SFD. This unsigned 7-bit value can be looked on as a measurement of the chip error rate, although the radio does not do chip decision.
As described in Section 23.9.7, the average correlation value for the first eight symbols is appended to each received frame, together with the RSSI and CRC OK or not-OK, when FRMCTRL0.AUTOCRC is set. A correlation value of approximately 110 indicates a maximum-quality frame, whereas a value of approximately 50 is typically the lowest-quality frame detectable by the radio.
Software must convert the correlation value to the range 0–255 as defined by [1], for instance by calculating:
LQI = (CORR – a)b
limited to the range 0–255, where a and b are found empirically based on PER measurements as a function of the correlation value.
A combination of RSSI and correlation values may also be used to generate the LQI value.

My devices have a stable LQI, of course shifting a little bit up and down (but not to 0).
When using a CC2538 it is much lower then using a CC2530+CC2591. (see my post above)
So for me it is clear that the LQI for the CC2538 is much lower. For both I use an external antenna.

[thiscantbeserious]

Are you perhaps also doing the same mistake that the OP did? Comparing two different zigbee-channels (11 vs 25) on different hardware as it would be the same?

Higher frequency also means less troughput and penetration, even if there's less interference. Now depending on the hardware if you throw in the amplification it could also make matters worse if your signal is stronger.

Most importantly if you want to compare them start by using the same channel.

[piit79]

Higher frequency also means less troughput and penetration, even if there's less interference.

@thiscantbeserious Sorry for replying to an old message. I don't think there's any reason for lower throughput on higher frequencies - throughput mainly depends on bandwidth and modulation, which is the same for all Zigbee channels.

Higher frequency means worse penetration in general; however, the difference between Zigbee channel 11 (2405 MHz) and channel 25 (2475 MHz) is just 70 MHz, or less than 3% - the effect will be negligible.

Of course, RF conditions and interference with Wi-Fi can make a big difference.

[codmpm]

Hi again.

We are currently discussing a problem with the CC2538 where it "forgets" every pairing after a reboot or power loss. I can reproduce the behaviour on my Raspberry Pi Module (UART) on zigbee2mqtt with all three firmwares: modkam, revierline and jethome.

zigbee2mqtt 1.17.0
zigbee-herdsman 0.13.46

Can someone test this with his implementation, either UART or USB? Maybe @reverieline or @Koenkk can comment in this. Sorry for @'ing you directly.

For reference:

Thank you an Cheers,
Patrik

[thiscantbeserious]

Oh I recon - I messed up the models here, shame on me!

Either way don't expect that issues to be gone completely with the CC2652RB in relation to having a stable firmware.

[codmpm]

Absolutely... I also can't reproduce this with the "very old" CC2530. Neither with Z-Stack 1.2 nor 3.0.x on CC2530.
Only on CC2538 UART. I've not tested CC2538 USB myself, but someone on the homegear forums tested it and it worked on the exact same hardware.

[Multipage]

I have this problem also with my CC2538 (USB).
If power is lost ( i had a power failure today) every pairing is 'forgotten'. The devices are stil in HA and in Zigbee2MQTT but not responding.Reboot doesn't do anything. I will have to force remove them and re-pair to get it working again. If you have 2 devices and enities are not renamed not a big problem.....but i have a lot more.

Anything i could do? I haven't re-paired them all yet

[glsf91]

hey only have a pcb antenna. Working on a pcb already...

There is a pcb already for the ebyte module. Did you see: https://github.com/egony/cc2652p_E72-2G4M20S1E/wiki

[codmpm]

I know, but this will interfere with the CC1101-SPI Module for the PI I also build. Need to "move" it a bit and I will you a more suitable LDO. Nothings final, yet.

[ljakob]

Hi,
if anybody want's to solder his own PCBs based on https://modkam.ru/?p=1112 here are some relevant links:

• My order at DirtyPCB - you can just reorder
• USB JTAG-Adapter
• Gerbers
• BOM with direct links to Ali-Express for all components
• Coordinator Firmware
• Router Firmware

I haven't received my boards yet but this looks like the easiest solution to replaced my CC2531 based setup.

Have fun

[frank-f]

Have you tried to just connect 3V3, GND, RX and TX? I could imagine that's all it needs.

[hallard]

Have you tried to just connect 3V3, GND, RX and TX? I could imagine that's all it needs.

This is indeed just what's needed, you can even wire a GPIO to reset pin as a cherry on the cake :-)

[davidmonro]

Yes, I've just connected the module 3v3, gnd, TX and RX directly to the appropriate pins on the pi (1, 6, 10, 8) . You do need to disable the login process and the kernel logging which goes there. I suspect you can do that with the raspi-config program, or else

systemctl disable serial-getty@ttyAMA0.service

and remove the 'console=serial0,115200' bit from /boot/cmdline.txt

And reboot (the kernel logging won't be disabled until you do).

Then install either zigbee2mqtt locally, or use ser2net with zigbee2mqtt running elsewhere (I do the latter now, I find it easier to keep it up to date running it in docker on my main server than on a 1st gen model B pi - with a faster pi YMMV. I'm also not using it for interactive stuff like lights where I gather that setup can be a bit laggy, I'm just doing sensors).

Oh, serial port is /dev/ttyAMA0, so my ser2net config line looks like:

20108:raw:0:/dev/ttyAMA0:115200 8DATABITS NONE 1STOPBIT

or in the local zigbee2mqtt case:

serial:
port: /dev/ttyAMA0

I've not done the extra gpio to reset the module, but once my proper external antenna arrives I may well add that feature.

[elastic-paul]

@davidmonro @frank-f Sorry to be dumb on this but can you confirm the pins on the CC2538+CC2592 board please?
3v3 - GPIO 1 - PCB VCC (3)
GND - GPIO 6 - PCB GND (1)
TX - GPIO 10 - PCB PA1 (23)
RX - GPIO 8 - PCB PA0 (22)
Does that make sense?
Thanks

[davidmonro]

Oops, sorry to take so long replying. Yes, that looks exactly right. I've added another wire from pin 7 of the pi to the RST pin on the CC2538+CC2592 board so I can reset it as @hallard suggested.

I've printed a case to hold it and an original Raspberry Pi Model B. (If I did it again I'd move the antenna to be offset away from the cables, and the mounting tab to the other side so it didn't make it difficult to get the ethernet cable out)

I'm planning on using ser2net with zigbee2mqtt in a docker container on my internal server, as a direct replacement for my
CC2530+CC2591 (which is using ser2net on a different pi and has reached the max number of devices it can handle).

[hallard]

@ljakob, Interesting, thanks for sharing, I've just received my custom design today, should be working autonomous with ESP8266 or USB or direct on RPI, perfect for testing all case, just need to test before publishing :-)

[hallard]

For those interested, i designed a 3 in 1 zigbee adapter that use cc2652p:
https://github.com/Gio-dot/Z-Bee-Duo

@gio-dot , yours is just awesome, love it

[codmpm]

@gio-dot nice one. Currently working on a CC2652 variant for the Pi's GPIO. Albeit not using the ebyte module as the external antenna situation is a little bit unsatisfying.
I've already asked ebyte if the plan to make an E72 witj u.Fl-socket, but they declined.
Right now using a Duoweisi module and works great - will be open-sourced like my CC2538 module.

Here's a picutre of the prototype:

CC2562 Raspberry Pi ZigBee Module with Z-Stack 3.x

[hallard]

Hi all,
I assembled the 3 boards, I tried 1st with RPI Zero (after remapping real UART of course) because I don't have these SMD JTAG connectors to solder (if someone has a reference I'll take it)
First thing, I was able to put device in bootloader with reset + flash button (no need to do tricky things) and then flashed firmware MODKAMRU_V3_UART-no-flow-control_with_SBL.hex with cc2538 prog After success, led started to works indicating device was starting (red powered up, blue blinking when association enabled). Then installed zigbee2mqtt with front end (on same RPI), all is fine, awesome.

@papperone, correct I'm aware of this. I intend two things (waiting any support for stack V3, why not one day), run as standalone transparent WiFi Serial/TCP bridge and also to simplify firmware flash of the CC2538 like it's done with CC2531 (I mean ESP will flash CC2538)

Now, I'm a bit new on all this stuff, just to be sure got some questions:

• I can't use this board with USB or Serial with same firmware, if I intend to use with Serial (example on PI) I need to flash MODKAMRU_V3_UART-no-flow-control_with_SBL.hex and to use as USB MODKAMRU_V3_USB_with_SBL.hex is that correct?
• Is it possible to flash the CC2538 with native USB (I mean connected to D+/D-/GND/5V and 5V=>3V3 converter) ?
• why there is so much different firmwares? Latest looks like to be jethome there

Thanks to all contributors

[frank-f]

Are you sure the serial bootloader flag is currently enabled on your stick?

[Krzemq]

It's new stick, so it should be, but i'm not sure. Do i need JTAG to check it or i can do it with simple UART-USB stick?

EDIT:
If i need to use JTAG to enable bootloader, how to connect it to the board? I see pads for JTAG, but what type of connector do i need to solder to it?

[marsjan155]

@Krzemq
some of the new boards I purchased have been locked(or disabled bootloader), JTAG can unlock them

[Krzemq]

Well, I'm trying to flash cc2538 with JTAG, but when i connect board to the J-link its green red starts blinking and it cannot connect to the board :/ What am i missing?

EDIT
Okay, it was AMS1117-3.3 fault, because i left it connected to hallards board pins and it got really hot. Now i'm worried if my cc2538 board isn't fried... Because JTAG (however not blinking) cannot connect to the board :/ Is there anything than checking proper connection that could go wrong? Flash/reset button needs to be pressed or something?

[marsjan155]

@Krzemq don't need to press anything, just Connect from app

[hallard]

Ok, step 2, flash firmware with FTDI (3V3 regulated of course) using WeMos D1 Mini header and my computer (not anymore on RPI connector), has never been so easy, worked like a charm.

Then putting a WeMos D1 Mini with ESPLink firmware (awesome by the way) configured as follow (pin of my board)

And configure zigbee2mqtt with tcp remote ip instead ttyAMA0

homeassistant: false
permit_join: false
mqtt:
  base_topic: zigbee2mqtt
  server: 'mqtt://192.168.1.8'
serial:
#  port: /dev/ttyAMA0
  port: 'tcp://192.168.1.206:23'
advanced:
frontend:
  port: 8080
  host: 0.0.0.0

Restarted zigbee2mqtt service, and voila you have CC2538 WiFi so you can put it anywhere you need and keep zigbee2mqtt elsewhere (NAS from my side) :-)

Last but not least, board fit on enclosure of course (it was designed for), I should have placed USB elsewhere since it can't fit on WeMos, but used some USB breakout and dedicated connector below WeMos

[papperone]

may I ask you how stable is this setup?
all my experience with SER2NET show slow response, lags and sometimes a completely frozen ESP8266

[hallard]

Interesting, I've done that for a friend, so not really testing is, but I will for testing
BTW, which serial/bridges did you tried? Tasmota, ESPLink, ESPEasy, custom?
I'm not using ser2net service/daemon, just configured zigbee2mqtt to remote IP (in fact it's the same feature than ser2net but not using this daemon)

[gio-dot]

may I ask you how stable is this setup?
all my experience with SER2NET show slow response, lags and sometimes a completely frozen ESP8266

I experienced the same issues with my prototype made with wemosD1 running Tasmota (only used for ser2net) and a cc2538+2592: very laggy especially when changing dimmers, dimmable lamps or switches. I stopped to work on it after 2 hours...

[hallard]

Good point guys, I experienced disconnections with esplink, (10/day) so I tried latest tasmota 9.2.0 build (manually)with Serial to TCP bridge and no disconnect since 48H, looks awesome.

Config is like that, the relay drive the reset pin of CC2538 so I can remotely reset zigbee module :-)

I must admit I'm not using it really intensively, just up and running for testing but it works

[Kosygor]

Does anyone checked for how long this config (c2538 + wemos) can run on battery ? Please if You have checked provide battery specs. This would be great since You can place one coordinator in center of house and not rely on AC routers.

[MaxVonEvil]

Happy friday everyone. Quick question to the esteemed panel.

I recently bought a C2538+C2592 module for Rasberry Pi
The module integrated flawlessly with Zigbee2Mqtt and is giving me better signal than I ever had.

However I'm seeing pairing issues with certain devices, specifically Sengled Element Classic smart bulbs. model E11-G13) They never seem to be detected by the coordinator, while other devices will pair instantly from half way across the house. It should be said that same Sengled bulbs pair instantly and work as expected with a Hubitat C7 hub. This tells me respectively that the bulbs are fine and the signal from the pi module is good too, which leaves me wondering if these bulbs are doing something which the firmware doesn't quite understand..?

I've determined the module is flashed with MODKAMRU_V3_UART-no-flow-control_with_SBL, yet it looks like this firmware is almost a year old.

My question is if there is a more recent firmware which potentially could solve this conundrum or there are other suggestions to consider. Thanks in advance!

[codmpm]

You can upgrade to the jethome firmware, see https://github.com/codm/cc2538-raspberry-pi-module#serial-via-gpio
JH has SBL always enable, so just use the UART firmware.
If you flash a firmware without SBL you wont be able to use the described way anymore, as the SerialBootLoader is missing. No dead end, but then you have to use JTAG for flashing new firmware.

In the meantime we ship the module also with JH as it is more recent.

[MaxVonEvil]

@frank-f , @codmpm, thank you for the suggestions!
While I did change my Wifi AP's channel to 3, I think changing the Zigbee channel in the configuration.yaml is next on the list to try. I read somewhere that many Zigbee device prefer channel 20, and I just noticed the default channel seems to be 11. Besides it's quick to test and reversible. I guess we'll see.

UPDATE Feb-6: Changed channel to 20 and it seemed to do the trick! All the devices I've added are pairing and there was much rejoycing! ;)

That said, in parallel I pulled down the c2538prog tool and compiled it on my Pi, yet this is my first time using it. I hope you guys don't mind clarifying a few items. I'm proceeding with caution, as I don't have a JTAG programmer at hand.

1. Compiling the c2538prog flash tool, I noticed it references hex.c and hex.h which seems to be a basic bootloader. Would I be correct that I don't need to change anything there prior to compiling? I'm guessing the basic bootloder is the code that bootstraps the module and loads the SBL that I am flashing commandline.

2. Is there any way of backing up the existing firmware via the UART, using the flash tool or something else?

3. Looking at the command-line help for the flash tool. it looks like I need to use the JH_2538_2592_ZNP_UART_20201010.hex file. Just curious, what's the corresponding .bin file for? (I presume the .patch files are for upgrading from an older version, i.e. I won't need them to flash from scratch)

Thanks in advance!

[SVhuMMer]

Hi there, I'd like to follow up on this topic re. changing the ZB channel. I am having trouble connecting a few specific devices to my CC2538 stick, thought maybe the channel swap will do the trick. Do I get it right that I can add this to the advanced function section of the Zigbee2MQTT configuration.yaml? And if I need to revert back to the default channel, all I have to do is delete this and restart?

[piit79]

@SVhuMMer Unfortunately, as far as I know, to change the Zigbee channel you need to re-pair all the devices...

[SVhuMMer]

Thanks a lot, indeed, it did make my devices unusable lol! However, switchnig back and fourth between channels, I ended up returning to Ch11, and oddly enough, those devices I could not connect earlier were able to join the network after this channel rodeo - the stick did some sort of "deeper reboot" - I dunno how to describe it precisely, but it went all black (LEDs turned off), then slowly rebooted, and somehow it solved the problem with the two Sonoff ZBMinis I had trouble connecting before :)))

[ljakob]

Hi,
I just wanted the thread here to know that I've successfully soldered 3 modkam USB modules (see image below). You should have done some 0805 soldering before. If someone in Switzerland needs some unpopulated boards drop me a line. I've not yet moved my devices to the new network yet but RF performance seems a bit better than my current CC2530/CC2531 setup.
Cheers Leif

[ljakob]

I've fully migrated my home network with about 40 devices to the new setup (1 modkam coordinator and 2 routers) and it's working great. Response times are "felt" better but not measured. The coordinator is running in an Openwrt access point that forwards the connection to a Linux box with ser2net.

[Kosygor]

Hello wanted to share my project.
I am running CC2538 from aliexpress via UART and ESPeasy, with flashed JETHOME FW with this adjustable antenna from my RTL-SDR ( I found originall one bad for receiving signals all arond house).
Aim was to not rely on routers so when using via serial bridge it can be placed in the middle of house. Works great with HA in docker on Debian 10.
Only disadvantage of PCB is that it does not charge battery ...
Anyway for anyone trying to do same thing here and here you can find some help.
Latency is imperceptible .

[handfreezer]

*Hello every one, I'm quite lost.
I succeed in doing a CC2531 usb-Zigbee very easily.
As I wanted to extend my network, I tried to do the same with a CC2538 (link Aliexpress):

I tried the modkramru v3 usb and the JetHome 20201010 (first uart without usb enumeration, then I tried Jethome with usb and I got USB enumeration).

BUT, I'm falling with this error:

May someone have an idea or can help me?

Note that I didn't connect jumper between PC0 - PC7 and I placed the power jumper on USB . Also, I'm using SEGGER JTAG, cleaning memory before flashing without error then programming with verify without error (using J-Flash v6.98e). The CC2538 on board is a CC2538SF53.

Thanks in advance

Very long answer, but I hope enough to get help...:

My config : debian Buster 10 + Z2M git:master (all updated 2 days ago, I had to npm install deep-diff). Z2M is running under an unprivilege user, but the user is in group dialup which give him access to /dev/ttyACM0 (it is working well with a CC2531).
To make the migration, I stopped Z2M, then removed "data" dir content, and put back a copy of configuration.yaml (devices list removed).

Process of test: I'm connecting it through direct USB without RS232<>USB converter. I mentionned uSB and UART speaking about JH firmware, because I'm a little bit lost about the differences between each. I will work now only with JH_2538_2592_ZNP_USB_20201010.hex except if someone explian to use the other one.

[handfreezer]

I fill like the module zigbee-herdsman tried to set a value in nvram but failed.
But from that point, I'm a little bit lost : I don't know why it is doing so, what the write is as information, if it is legitimate to do so, might it be a pbm with the firmware (in this case, should I have to open an issue on jethome firmware github?)...

[Kosygor]

@handfreezer Sorry for such long response

My config

If test given by z2m docs runs correct it should be enough.

Process of test:

First of all if You have exact board that You have provided photo it seems like it is only CC2538 + CC2592. Twist is: according to documentation and few post here is looks like CC2538 supports USB connectivity directly. But compered to mine version it lacks CP2102 (UART to USB) so why there is such diffrence.
In fact I only launched it with UART (via both serial/tcp and external UARTxUSB - FTDI programmer) so I do not have big experience with USB.

Few ideas, maybe some of them to obvious:

• if You use /dev/serial/by-id/usb-Texas_Instruments_CC2538_USB_CDC-if00 device location You should check write permisions for that location not /dev/ttyACM0;
• also try to add serial/by-id location to config - unless You are sure that it is mapped to ttyACM0 correctly (i am not pro with that by it seems that ls -l command will show redirection);
• Your config compared to location from this tutorial lacks port0 this may be a clue;

But assuming anything above is not problem log seems to be good ...

• until this moment startZnp Item 'hasConfigured' is invalid, got '{"type":"Buffer","data":[]}', expected '{"type":"Buffer","data":[85]}' +19ms and by this it seems like it is problem with old data stored in NVRAM. I would swear that I had read about this but now I cannot find anything but this and this.

Problem is I am not advanced enough to guide You through NVRAM staff. Except for just one tip:

• did You erased chip in J-flash before flashing firmware ?

I did erase it and did not have any similar problems.
Additionally please try different panID I am not sure at which point Z2M stores it but it may be crucial.

[handfreezer]

First, many thanks for your answer.
To be short:

• Z2m docs test are fine
• my device is simpler because of no USB<>rs232 adapter on board, but using direct USB from CC2538 only (so JTAG is necessary to flash the device)
• I erased the flash by jtag, then read back and get all to 0xFF, and only then I flashed the USB JetHome firmware

Finaly, I used the script zStackEraseAllNvMem.js to erase the memory (return a success message, but when running twice, few memory space still not erased:

node scripts/zStackEraseAllNvMem.js /dev/serial/by-id/usb-Texas_Instruments_CC2538_USB_CDC-if00

[handfreezer]

Hello, and I'm back to close my problem : As you indicated to use only serial from CC2538 and not the USB interface, I plug a ftdi232 on PA0/1 externally , then flash the jethome UART firmware, erased nvram, and then launch Z2M : it works! SO: I can say my CC2538 chip is not in a bad state, but the USB jethome firmware might have a little bug (I don't think the board is defective as the USB interface can enumerate correctly and Z2M start communicating, and also zStackEraseNvRam seems working)

So we can consider my problem as solved. Thnkas for your time.

[Morphy99]

Without going through the 305 hidden replies, can anyone answer this question for me quickly please? I'm looking at recommending hardware for a 200+ Zigbee network, mostly routers (bulbs). Would this coordinator be the best solution as it supports up to 400 routes or maybe splitting the network into two instances of Z2M with CC2652s?

[Morphy99]

Thanks. It's not too clear to me but I understand the direct children limit is mitigated with routers. But I was under the impression the routes stored in memory can be an issue? That was the 400 figure I quoted from here
I've read a post with a ZHA user complaining about Conbee II and over 100, and Z2M CC2652 user with two networks for ~150 devices.

[Kosygor]

I am bad and explaining please check this

[NathanSweet]

@Kosygor Did you ever find an answer? I have the same question (for ~200 Hue bulbs).

[co-Palko]

In our experience, more than 150 devices on the CC2652 cause significant delays. Therefore, it is better to divide the network into several segments. In the case of simple sensors with rare data sending and a small number of clusters, the network will work up to 200.

[martin3000]

the cc2652 can be flashed as a coordinator and as a router, so it is easy to split the mesh.

[martin3000]

I have build sensors with an esp32/esp8266 module for use in my home assistant installation. I connected arduino sensors like UV sensor with the esp32 board via SPI or I2C.
Now I would like to use zigbee instead of wifi. Is the cc2538 multi connect board the right thing to start with?
Or can I do the programming directly inside the cc2538, without the esp32?

[verjus]

Yes, you can program the cc2538 but it's not easy. Personally, I prefer the Nordic nrf52840 for this with the Nordic SDK. More info here

[martin3000]

where can I find an instruction what module to buy, what tools to download (ubuntu) and what code to use to build a zigbee temperature sensor with an i2c oder spi temp. module?

[verjus]

The SDK I linked above contains examples of Zigbee applications, such as light_control and multi_sensor. The SDK supports Linux/gcc and other. Very well documented on Nordic's site. This excellent project my be of interest to you as well. Most modules are compatible. I used this one but this one should be better value (didn't test it).

[martin3000]

Thank you, ptvo.info sounded interesting! But after flashing the ptvo firmware onto my cc2652rb usb stick, the stick was bricked because the firmware does not support a serial boot loader.

[HoangThang1999]

Hi guys
I'm having some issues with an unexpected short address change of router , end_device
. I use coordinator cc2538+cc2592
. i am not sure how to fix it???

[RAMBORG]

hi i need help, i bought a cc2538+cc2592 with usb

das flashen hat funktioniert?
hat der keinen bootloader, kann man den nicht über usb flashen?
was ist denn die ausgabe von lsusb ?

[RAMBORG]

ich finde kaum quellen über das teil,
viele schreiben, flashen über usb nicht möglich.
deshalb, bin total ratlos.
habe mir jetzt so einen debugger bestellt und werde es damit testen.
beim einstöpseln und gedrückter rst taste startet er jetzt auch einfach.

deshalb brauche ich jetzt höchstwahrscheinlich den debugger.

die ausgabe ist usb-1a86_USB_Serial-if00-port0

[RAMBORG]

wollte eigentich garnicht so viel zeit in das alles investieren, dachte es wäre einfacher, wie z.b. bei den wemos d1 minis etc.
flashen und plug and play.

beisse mir die zähne hier aus :-D

[martin3000]

das klingt aber alles gut. ich sehe bisher nichts, was falsch ist. du könntest vielleicht mal mit zigbee2mqtt spielen, ob du mehr erfolg hast.

@RAMBORG @martin3000 Could you please stick to English? It's not very nice talking "between yourselves" in German like that...

Hi,

I've build a board with CC2538+CC2592 on aliexpress but I cannot flash the firmware on it. I've put the CC2538+CC2592 module on the cod.m board that I've ordered to JLPCB using the files on https://github.com/codm/cc2538-raspberry-pi-module.

I've tried to flash the firmware on the module directly plugged on a raspberry pi using the [cc2538-prog] but I think it is not detecting the board (message is bootloader not detected). I'm holding the flash switch and pressing reset briefly to enter boot mode, but I don't know if the module is in boot mode. I don't know if the board is working or how to check if everything is well connected because there is no feedback on the module (there is no power LED). I don't have a JTAG proggramer so I cannot test to flash the module with it. Is there any way to flash the module using FTDI UART-USB converter?

Many thanks for your help.

Regards

Hey....
obviously the error message seems to be right and there is no or a deactivated bootloader on your CC2538.
Have you checked cc2538-bsl for flashing? https://github.com/codm/cc2652-raspberry-pi-module#cc2538-bsl-preferred

Maybe you can try out to use OpenOCD (https://gist.github.com/hwhw/fc43892785aa84913d03495c97b0f25a) to get the bootloader on the CC2538 or get a cheap JLink knock off from Aliexpress. Had luck with those in the past and they sell some adapters with it so you can directly hook it up to the board.

Hi codmpm, many thanks for your response.

I'm trying one fork of OpenOCD to directly flash the firmware but I'm getting the following error.

I don't know what I'm doing wrong!

I've could connect using telnet but once I'm connected I don't know what I have to do.
I've sent the messages mww 0x400D300C 0x7F800 and mww 0x400D3008 0x0205 but I think these are not doing anything because if I send mdb 0x0027F800 2048 this is what I've got.
