rflink wifi board and hardware watchdog

[brian-f]

Hi, the official wifi daughter board from Nodo-shop has an hardware watchdog (ATtiny) which keeps resetting the nodemcu.

In ESPeasy this watchdog is supported (WD), the value to set is i2C "38". Is it possible to add this to the code?

https://github.com/letscontrolit/ESPEasy/blob/mega/src/Hardware.ino#L61-L81

if (Settings.WDI2CAddress != 0)
  {
    delay(500);
    Wire.beginTransmission(Settings.WDI2CAddress);
    Wire.write(0x83);             // command to set pointer
    Wire.write(17);               // pointer value to status byte
    Wire.endTransmission();
    Wire.requestFrom(Settings.WDI2CAddress, (uint8_t)1);
    if (Wire.available())
    {
      byte status = Wire.read();
      if (status & 0x1)
      {
        String log = F("INIT : Reset by WD!");
        addLog(LOG_LEVEL_ERROR, log);
        lastBootCause = BOOT_CAUSE_EXT_WD;
      }
    }
  }

and

https://github.com/letscontrolit/ESPEasy/blob/mega/src/ESPEasy.ino#L764-L770

  // I2C Watchdog feed
  if (Settings.WDI2CAddress != 0)
  {
    Wire.beginTransmission(Settings.WDI2CAddress);
    Wire.write(0xA5);
    Wire.endTransmission();
}

thanks

This is a specific case so I will not implement it. But you are free to fork the code and add it if you want.

Anyone found a solution for this or point me to code that has this implemented i now to have the rest issue because i'm using the original rflink wifi board

@brian-f @rverheijdengit I am re-opening this issue. I have some time to try it. Problem is, without the hardware it is difficult to know whether it works. If someone volunteers to test, I am ok to try to add the code as a compilation option. Please let me know.

Ok, this was tested and discussed: https://www.letscontrolit.com/forum/viewtopic.php?f=12&t=7495

I shall include it in the next revision as a compilation option.

Implement in dev branch, will be available in master soon
