Is it possible to use ESP8266's OTA capabilities?
-
Today I found an example in dev branch named GatewayESP8266OTA... does this mean it is already implemented? Or at least it's been worked on? Could please someone explain how to use?
-
@tekka thanks a lot for that info. I already tried that some time ago and gave up.
I flashed the OTA gateway and it works fine. Only when trying to ota upload I get problems. The Arduino IDE says
[ERROR]: No response from deviceand in the serial console I see the following:0;255;3;0;9;read: 1-1-0 s=1,c=1,t=1,pt=7,l=5,sg=0:39.1 sleep disable Error[1]: Begin Failed 0;255;3;0;9;read: 1-1-0 s=2,c=1,t=0,pt=7,l=5,sg=0:23.8Do you know whats happening there?

@tekka did you used password protection for OTA update or any other security feature? Did you change anything in the sketch except SSID and password for wifi?
@Anduril No, I simply followed these instructions:
https://github.com/esp8266/Arduino/blob/master/doc/ota_updates/readme.md and used this sketch for testing:

@tekka do you have and NodeMCU Devkit 0.9 or 1.0? I have a 1.0 and get the error. But I use it with fixed IP on the gateway sketch, maybe that's a problem. It uploads ok via serial. But when uploading via wifi (changed static ip for testing) it stuck. Maybe I will try it with dhcp enabled.

@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:

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...
