Help Moving from a wired W5500 to a wifi ESP8266

[AdamWithHap]

Hi Juraj,

Thank you so much, this is a brilliant library. I have been able to send sketches to my Arduino (Mega) from another room!

I am moving and will no longer have a wired connection near my Arduino, however, a friend has kindly given me a LoLin NodeMCU v3 ESP8266 wifi board.

I has been a while since I set up the wired connection and I'm looking for help in how to move from uploading via the w5500 to the ESP8266.

I have a Arduino Mega 2560. I used an USBASP programmer to flash the Mega with the Optiboot bootloader, and updated my programmer boards file as per you instructions. So now I select upload using programmer and hey presto my arduino is re-sketched.

I am currently using the Ethernet.h library for the w5500.

A couple of questions, which library do you suggest using for the ESP8266 and do I need to use the USBASP to reflash in the mega in any way or can I just alter my sketch adding the wifi library and SSID/password, flash it using the ethernet, then disconect and add teh esp8266.

My appologies if this is a little vague, as I said it had been a while since I set it up originally.

Thank you again for this amazing piece of work!

does ArduinoOTA work for you over W5500 Ethernet?
if yes then just replace the Ethernet library with my WiFiEspAT library

Hi,

Sorry, my bad communication. Thank you for the reply!

Updating sketches on my Mega OTA through a w5500 works perfectly. Using your instructions I flashed Optiboot and used your boards. The only big issue I has was my USBAsp was a cheap clone from amazon and it's settings were vaguely different than what was in the default programmers.txt file so I had to change it.

Hi,

Sorry, me again. I think I am missing some thing fundamental in what I am doing. My guess I have the pin's wired incorrectly.

Currently I have pins 19/18 on my Mega wired to D1 and D3 on the Nodemcu

If I use this code on the Mega:

void setup(){
 Serial.begin(115200);
 Serial1.begin(115200);
 delay(2000);
}
void loop()
{
  Serial.print("MEGA");
  Serial1.println("NODEMCU");
  delay(5000);
}

and this on the nodemcu

void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(115200);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }
}

void loop() { // run over and over
  if (Serial.available()) {
    Serial.write(Serial.read());
  }
}

I can see NODEMCU being displayed via the IDE Serial monitor on the nodemcu.

I've flashed the node mcu with the 1.7 firmware and the 1.5.4 that come with it. However when I run your CheckFirmware sketch from WiFiEspAT/Tools section in IDE Examples menu. It does ends with "Communication with WiFi module failed!". I've check my wiring and As the above example works. I'm slightly as a loss. My guess is I'm connected to the wrong pins on the Nodemcu. DO you know which ones I should use?

Thanks again for your patience.

Adam

[JAndrassy]

thank you for the coffee.
SDK 3 contains AT 1.7 https://github.com/espressif/ESP8266_NONOS_SDK/releases
D1 and D3 are not io 1 and io 3 so not RX and TX. the Serial pins are label RX and TX on NodeMcu.
wiring is RX1 to TX, TX1 to RX and Gnd if you power the NodeMcu with USB. I don't remember if it is possible to power the NodeMcu over the 5 V pin.

[AdamWithHap]

ok, thanks for the above. It looks like most of my issues have come down to the esp8266 nodemcu boards. For the life of me I can't get firmware 1.7 on and for it to respond to a simple AT command. for reasons I don't understand, version 1.7.5 will flash using the addresses in teh read me and does respond (via the usb cable) to an AT command.

Using your examples I have, from the mega, connected the esp8266 nodemcu (persistently) to my wifi. YAY! As you put above i did have the pins wrong to.

On the the final goal of flashing a sketch OTA. Again using your OTA over serial example I flashed that sketch via the usb.

As I test I've added a simple blink to the mainloop, so see if it updates properly. Unfortunately I get this error message:

Sketch uses 17178 bytes (6%) of program storage space. Maximum is 261120 bytes.
Global variables use 1197 bytes (14%) of dynamic memory, leaving 6995 bytes for local variables. Maximum is 8192 bytes.

Connecting to board ... done
Uploading sketch ... done
Flashing sketch ... Error flashing the sketch
Failed programming: uploading error: exit status 1

My guess from your trouble shooting is I've not put the right optiboot on and it's not flashing the final part:

Upload returns OK but the sketch is not replaced.

The final loading of the uploaded binary is in some cases not under control of the ArduinoOTA library.

For AVR InternalStorage upload the final loading is done by the Optiboot with copy_flash_pages function. Optiboot 8 without copy_flash_pages will successfully store the binary to upper half of the flash but will not copy it to run location in flash.

Do you know if the latest optiboot has this included or is it just something you've done and can you point me towards a version for the mega please.

Thanks,

Adam

[JAndrassy]

if OTA worked with Ethernet, you have the right Optiboot.
do the basic example of the WiFiEspAT library work?
try higher baudrate for communication with the AT firmware. (there is a 'example' sketch to set higher baudrate). 250000 baud should be ok.

[AdamWithHap]

Using your chanegserial sketch I can successfully change the baud rate of the nodemcu.

Using the serial monitor on the Arduino IDE I can successfully send and AT command on the new baud rate and receive an OK. The mega on the other hand seems not to be able to do so. All i get is wifi module not found on the mega serial output and garbage on the node mcu out put. Only a 112500 baud rate seems to work from the mega to the node mcu. SO I'm still stuck with the same error message as above. At the bottom is the full output. Is there any debugging you can suggest to see where it is going wrong? If I have the wrong ip/password then I see those messages it's just this last section.

I thought I would look back at your wifilink firm ware to try, but I see it is only set to upload for the mega328 rather than the 2560 I have.

If I can't get this working in the next couple of days I'm going to go back to the ws5500 and a wired connection.

Thank you so much for your help.

first the WiFiEspAT library must work. as I understand it works for your setup if baud rate is 115200. the WiFiClient example shows the Arduino logo?
then you set the baud rate on both sides to 250000 and it stopped working?

[AdamWithHap]

Right, after some messing about. I configured the nodemcu to accept incoming serial at 500000 and the mega to the same on serial1.

i can set persistent settings from the Mega to the nodemcu and the Serial Monitor on the Mega confirms this.

Using SerialWiFiOTA.ino as I base, I initially flash this to the mega using usb so ArduinoOTA is polling.
I add a blink led command to the main loop and upload using the programmer ArduinoOTA I set up.
On the face of it now, I get a success message:

Flashing sketch ... done
OK
Sketch uploaded successfully

This looks good!

However, the board resets, but the sketch is not actually updated. No leds blink.

The config seems correct as if I change the Ip it fails, if I remove the ArduinoOTA.poll the upload fails.

I'm soooo close. Any ideas on this one?

[AdamWithHap]

It looks like this, but I've sure I have the right version:

For AVR InternalStorage upload the final loading is done by the Optiboot with copy_flash_pages function. Optiboot 8 without copy_flash_pages will successfully store the binary to upper half of the flash but will not copy it to run location in flash.

will reflash optiboot and see....

[JAndrassy]

if OTA upload over W5500 worked, then Optiboot should be good

[AdamWithHap]

then I'm a bit stuck as to what to do next... Any ideas? It looks like it is all working but the sketch doesn't change.

[JAndrassy]

is the NodeMcu powered by USB or from the 5 V pin of the Mega?

[AdamWithHap]

It doesn't work when the nodemcu is powered from the usb, 3.3v or 5v.

same message but the sketch doesn't actually change:

I think I had that problem too sometimes so I try to investigate it on weekend.

[AdamWithHap]

Thank you.

[AdamWithHap]

I am at a bit of a loss for words. If I run the ArdinoOTA.exe from the command line the sketch is actually updated!?!?!?

I get the same messages as when it runs it from Arduino IDE though, with Connecting to board etc...

Command line:

C:\Users\Adam\AppData\Local\Arduino15\packages\arduino\tools\arduinoOTA\1.3.0\bin>arduinoOTA -address 192.168.1.183 -port 65280 -username arduino -password password -sketch "C:\Users\Adam\AppData\Local\Temp\arduino-sketch-601F0C58A8B848D0890BFD4053A8DD4F/SerialWiFiOTA_Hello.ino.bin" -upload /sketch -b

As far as I can see it's exactly the same...

Not sure if this helps at all, I suppose it could be an IDE 2.0 issue. This is the version I am running:

Hi Juraj,

I hope you are well.

I was just wondering if during your own investigations you have found out what the issue I'm seeing is or related to.

Kind Regards,

Adam

[JAndrassy]

I deleted my TODO note as you reported it works in IDE 1. IDE 2 has still many problems

[AdamWithHap]

Hi Juraj, I'm still having major problems flashing my Arduino Mega OTA. Some times it works, some times it reports that it works, but doesn't. IDE 1.8.9 or using the command line works more often but not with any regularity.

I borrowed an UNO and using you WIFILink library (The mDNS only seems to work with v2.4.2 or 3.x of the ESP8266 libraries) with the MCU_OTA turned on I can get this to upload sketches OTA. though it reports as the reset failing, it does actually reset and the sketch it updated.

I was thinking of using your WIFILink firmware with SPI turned on and trying to flash my mega OTA that way. Is that going towork or should I use a different set of libraries?

Thank you again for your patience.

Adam

[JAndrassy]

I have the ArduinoOTA library in a project with ATmega1284p. I use it with SD card storage and SD bootloader because the sketch is larger than half of the flash. It works good.

Simplest OTA with esp8266 is https://github.com/JAndrassy/lab/blob/master/AvrDudeTelnet/AvrDudeTelnet.ino

[AdamWithHap]

cool, thanks. WIll Try!

I'm kinda tempted to mail you my Mega and the nodemcu with the code and see if you can get it working. :-)

[JAndrassy]

my Mega with esp8266 is strange too. but that is just a testing setup.
what baudrate did you set for the communication with esp8266?

[AdamWithHap]

Hi,

I've tried 960, 57600, 115200, 230400 and 500000. It's much of a muchness, 500000 did seem to give me the best results but not by much.

[JAndrassy]

try 250000 baud. it is better for Mega than 230400

[JAndrassy]

I found my problem with OTA upload to my test setup with Mega. It was related to Eclipse Sloeber IDE I use. If I had Serial Monitor connected, the IDE reset the Mega after the upload tool finished.

[JAndrassy]

and it looks like in Arduino IDE has the same problem when using Upload with programmer and the Serial Monitor is open for the boards com port. the Mega is reset from outside before it can apply the update

[AdamWithHap]

Thanks for the update Juraj, will see if these sort my issues out.

[AdamWithHap]

Hi,

I have the avrdude telnet sketch uploaded to my nodemcu. I can telnet to it and have the characters I type in telnet printed in the serial monitor or the mcu.

I have set the serial baud rate of the nodemcu to 115200 as I understand this is the default sketch upload speed of a MEGA.

I have D1 (GPIO5) of the nodemcu connected to the reset pin of the MEGA.
nodemcu TX RX to RX0 TX0 of the mega
All of this is through a logic level shifter (and for testing just straight through)

The mega is powered through the barrel connector and the nodemcu from the 5v/grd of the mega. No IDE is involved.

I get these messages:

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00

if I connect the serial monitor and USB cable to the MEGA I can see these messages appear 0 0 0 0 0 0 0

Am I missing some thing blindingly obvious or am I just destined to go back to the w5500 as so far that's the only way I seem to be able to connect OTA. I even tried a bluetooth module and setting it up as a comm port but I seem to have bought a fake one so that doesn't work either...

[JAndrassy]

did you try ArduinoOTA library upload with Serial Monitor closed?

for the telnet upload, can you paste here the command executed and complete output of avrdude?

[AdamWithHap]

• did you try ArduinoOTA library upload with Serial Monitor closed?

Yes, that seems to make no difference.

Will send the telnet command and output a bit later today.

[JAndrassy]

how large is you bin file? was the esp8266 powered separately for the ArduinoOTA test too?

[AdamWithHap]

Sketch uses 48642 bytes (18%) of program storage space. Maximum is 261120 bytes. - out put from IDE

and, yes the esp8266 was powered separately for the ArduinoOTA test too.

[AdamWithHap]

I think there is some thing up with my Mega's reset pin. I've been trying to use a HC-05 to upload code, I have an led set when the pin is pulled to low, I can see the led drop and return but only half the time does the upload start. With the avrdude telnet I can see the reset pin pulled low but it never seems to enter the upload mode...

I've also tried setting the baud to 250000 for the serial arduinoOTA from the nodemcu to my mega and that is flakey too. sometime works, sometimes doesn't.

[JAndrassy]

so now I tested with my 90 kB sketch binary of Regulator project. I have Mega with Wemos D1 mini on Serial1. It worked.

[AdamWithHap]

Hi Juraj,

Thank you for testing and your help. I have a HC-05 connected that (finally) consistently works uploading sketches. Though I've had to use different resistors in the reset circuit compared to those I've found in the tutorial. So for the moment I'm going to use that to upload to the Mega in my project.

For my next project I have an UNO and I can upload to that via a nodemcu using your WifiLink library. Will see if I can get telnet upload working on that when I have some more time.

Again, thank you for all your help and for building these libraries that we can use!

[JAndrassy]

the upload to Uno with WiFiLink firmware doesn't require the WiFiLink library. you could use EspLink firmware on which the WiFiLink firmware is based

[JAndrassy]

does your sketch use Watchdog?

[AdamWithHap]

No, it doesn't.
