Is it possible to use ESP8266's OTA capabilities?

[Anduril]

@tekka did you changed any of the standard settings for ESP flashing? I simply updated ESP8266 library and reflashed, but I get an reboot loop. In the serial monitor I see:

0‚~?–4“Ò¶£ÿOAaû0;255;3;0;9;Starting gateway (RNNGE-, 2.0.0-beta)

When going back to 2.0.0 it works without problems. Here my settings for flashing:

@Anduril I'm using the NodeMCU 1.0 (ESP-12E Module) settings / ESP 2.1.0 lib / and the latest MySensors dev (including PR#419 - there was indeed a rebooting issue before #419)...

[Anduril]

thanks a lot, working with newest dev build and ESP8266 lib version 2.1.0 as you said.

@Anduril excellent! Have fun :)

I'm trying to use the serial monitor but I'm always ask entering a password? Although I didn't used one?

Reflashing sketch via OTA worked without any issues.

Edit: Tried to use a real OTA password and it's still not working although I'm using the correct. ESP8266 Tools 2.2.0

to my last knowledge this feature is implemented but not working. If you want to see the serial monitor you have to connect physically.

Regarding the bootloops: how you structure your code seems to have an effect. If you have busy-waits in your code, you're more likely to encounter the WDT timeout. I restructured my code to be more interrupt driven and to complete more frequent cycles through the main loop(). After doing that, the WDT timeouts stopped.

That said, I don't know whether your bootloop is caused by a WDT timeout or something else. At least in my case, the debug messages being printed in the serial window specifically mentioned WDT being involved.

I presume debugging via network is not supported, I read some posts on Github but couldn't be sure if it was implemented?

By debugging, do you mean looking at the serial console output over the network, or something else?

Yes, serial monitor via network within IDE...

I haven't tried it yet but this plugin for serial monitor over network looks nice https://github.com/esp8266/Arduino/issues/1360
