Strange "wdt reset" about homie-esp8266 HOT 10 CLOSED

The issue comes from the Arduino for ESP8266 (see esp8266/Arduino#1017)
Basically, an ESP.restart() after a flash triggers a wdt reset.

To confirm this is the issue, try this:

1. Flash the firmware
2. Manually power reset the board
3. Repeat the config request/reset

You will see that the board is actually rebooting.

Note that when stuck on a wdt reset, you don't even have to reflash the firmware: just reset the board manually and it will boot in the correct mode.

Indeed, this doesn't appear when I hard reset power of the board after flashing !

We can leave this ticket open for documentation, until bug isn't fix in Arduino/ESP8266.

Resume: With NodeMCU 0.9 for every ESP8266, you need to manually power reset the board after flashing to have reboot working.

I'm not familiar with nodeNCU, Is there a way to reset it without plug/unplug it ?

from homie-esp8266.

Yes, let's leave it open for reference. It is not only a problem with NodeMCU, it is for every ESP8266 ;)

On NodeMCU 1.0 there is a RST button. It seems like NodeMCU 0.9 doesn't have such a button, so you'll have to power reset it!

Ok, thanks for the quick answer !

I do have 3 esp boards and all 3 broken, when i did flash wit espeasy R48, ide 1.6.5

Is there some one that have working option for this problem?

@Dylantje report your issue at esp8266/Arduino, this is not the place to do it as Homie has nothing to do with it. ;)

The v2.0.0 will rely on the 2.3.0 version of the ESP8266 for Arduino. This problem is solved in this version.

Eventhough, this bug has be closed sometime ago, here an observation, which might help others:
I had the following added to my platformio.ini and I observed the resets described above (about 5 s after startup). After I have removed the debug options, no more resets:

build_flags = -DDEBUG_ESP_PORT=Serial -DDEBUG_ESP_SSL -DDEBUG_ESP_TLS_MEM 
 -DDEBUG_ESP_HTTP_CLIENT -DDEBUG_ESP_CORE -DDEBUG_ESP_WIFI -DDEBUG_ESP_HTTP_UPDATE
