Hello, First of all, many thanks for your involvement,

I doing to try Chacon socket and I found your git to manage it via URL, I think to improve security it's so much better than manage directly by the cloud application..

I encoutered the problem related that I can't upgrade my socket with your bin,
What do you need to develop the fix ?

Intersting... another user already emailed me about his device not working with this firmware.
Then we discovered that it uses a different module (the LPB130) so I added a warning message on the README.md about this:
https://github.com/ljalves/hfeasy#hfeasy

Is your device this one: http://www.lumitek.cn/en/productsd.php?pid=1094
Check the model on the back sticker. Is it a "SW7201"?
I'm wondering if it is just the FR version or if all the newer products use the LPB130 module.

Anyway, this firmware should work and compile just fine on the LPB130.
I could find out that there are 2 module types: one with 1Mb and other with 2Mb flash.
After discovering which one they used on the device, get the toolchain (arm-none-eabi, available for linux and windows) and the SDK from HF:
http://www.hi-flying.com/download-center-1/software-development-kit-1/download-item-hf-lpx30-hsf-sdk-1mb-2mb
Then compile and test...
If I find one of these modules I'll build the firmware.

By the way, the LPB130 is a newer version of the LPB100 and major differences are:

LPB130 LPB100
CPU ARM Cortex-M4@160MHz ARM Cortex-M3@96MHz
OS mbed FreeRTOS
Flash 1Mb/2Mb/4Mb 2Mb
RAM 352Kb 128Kb

I looked at the lpb130 SDK docs and the internal webserver doesn't seem to have the same capabilities (add custom pages on code), meaning that the fw will not work as is (mqtt should work fine, but controlling by http will not).

Since lpb100 internal webserver is also pretty limited maybe I'll just code a simple webserver (or find an opensource one online) that will work on both modules.

I already installed the gcc toolchain (has to bee the 2016-q3 version) and SDK - everything seems to compile ok so all I need it to get my hands on one of the new modules...

Not sure if that's a good idea.
It can happen that I order one and it arrives with the older module (lpb100).

I now have a LPB130 module in my hands.
Will dump original firmware and start doing some tests.

I'll post here whenever I have a working hfeasy firmware for it.

An update on supporting this module:
I now have 2 of these modules in my hands: 1 is "bricked" from a wrong flash procedure, the other is working and has the original firmware in it.
I've removed the metal shield from the module expecting to see a flash rom... nothing!
This new module has everything integrated inside 1 single IC (explains why it is cheaper).

The bricked module can't even start the serial bootloader. I've connected the debug port and it spits out an hard fault error:

Panic...

Also I don't want to replace the original firmware in the working module before I dump it first.
So, to be able to do that I ordered and I'm now waiting for a new programmer that should support this cpu.

More news once the programmer arrives...

Hi! I got a Chacon Plug with LPB130 too... What's up about the custom firmware...?

Arut42 commented May 27, 2021

@ljalves you can't brick these devices ;-)
you can always program a new firmware over Uart 0 (debug Uart)
Just get these Programm from HF => "SingleDnload_V01.00.10_20180307"

I have one of these devices On the Label HF-LPB100-0 but it looks totaly different and inside is a HF-LPB230

Yes, but we'll never be able to get back to the original FW (no download option)...

I'll upload the FW for the LPB130 devices soon...

U say u have a second one.
Just download the FW over UART0
In the Bootloader u can use the command => flashinfo
U get all info about the flash chip u need
0x18000000 - 0x18001000 is internal Bootloader u can't write to it
with => upload 0x18001000 0x200000 (start len) len 0x100000 for 1MB flash
u get a full upload of the 2MB flash witch u can download to the brick one ;)

First, thank you for your job...!!

But... Can't access to any web page when I try "http:///iweb.html" or "http:///" ...
I'm sure about IP of the product because I gave it a static IP.
I tried with Safari and Chrome.
Chrome's telling me "ERR_CONNECTION_REFUSED"

Can you help me with the procedure to upgrade the firmware please...?

@urbamax,
Is it a Chacon plug you're trying to update? Weird that you can't access the update page... unless you have updated to latest FW where web update is disabled.

The alternative to webpage update is the UART bootloader method.
SecureCRT is fine and you'll need to solder some wires to access UART1 (the easy accessible uart pins are for UART0):
chacon_lpb130_2

You also need GND, VCC(3V3) and nReload pins (UART0 is not needed):
chacon_lpb130

Flash procedure:
WARNING: NEVER PLUG THE MODULE TO AC WHEN PROGRAMMING

  1. Connect nReload to GND and UART1 to a serial2usb adapter.
  2. Open SecureCRT (or any other terminal program that can send using Xmodem protocol).
  3. Power up the module with 3V3.
  4. At the same time you apply power, quickly hit 'space' several times until you enter bootloader (on SecureCRT).
  5. At the bootloader, select 'S' to send binary.
  6. Send using 'Xmodem' protocol the firmware (HFEASY_SERIAL_UPGRADE_LPB130.bin)
  7. After is done, disconnect the nReload pin from GND (leave floating) and power cycle the device - all should work now.

AGAIN: NEVER plug the device to AC line when doing this procedure. These devices are powered by a transformerless circuit and the GND pin can end up being connected to 230V AC (AC LIVE).
Even after disconnecting the serial adapter, if you plug the module in AC be careful not to touch any wires.

You can do testing after flash by just powering the module with only 3V3 (you may not hear the relay toggle) but all should work fine.
