Webserver and OTA Update - only one is working... why? #97

Hi, finaly I got the board Wemos Mega +WiFi R3 Module ATmega2560+ESP8266 working , was able to activate AT Firmware 1.7.5. and got the example sketches WIFIServer and the OTA WIFI working seperatly, now I am trying to combine these two, but whatever is started first is blocking the other...
why? How to get both running in parallel?

// waiting for connection to Wifi network set with the SetupWiFiConnection sketch
  Serial.println("Waiting for connection to WiFi");
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.print('.');
  }
  Serial.println();

      // start the WiFi OTA library with internal (flash) based storage
  ArduinoOTA.begin(WiFi.localIP(), "Arduino", "password", InternalStorage);


  server.begin();

  IPAddress ip = WiFi.localIP();
  printWifiStatus();
  Serial.println();
  Serial.println("Connected to WiFi network.6");
  Serial.print("To access the server, enter \"http://");
  Serial.print(ip);
  Serial.println("/\" in web browser.");

    // start the WiFi OTA library with internal (flash) based storage
 //ArduinoOTA.begin(WiFi.localIP(), "Arduino", "password", InternalStorage);

IF OTA is started first, Webserver fails... and vice versa...

sorry
in src/utility/EspAtDrv.h
uncomment
//#define WIFIESPAT_MULTISERVER

I forgot to document it

because standard AT firmware supports only one server

got it - well obviously I did not read that part - or dif not understand that OTA will be a second listening server... )-:

OK what are the easiest options for me? OTA Pull from a server? modified AT firmware? other?
Obviousli it does not make sense to have OTA updates without any feedback from the device - divice will be lokated in the attic...

Thanks for suggestions...

If you don't need UDP then Jiri Bilek's firmware is the best option. I use it

Thank You... just short question - not sure if something went wrong or if it works as designed...
Wifi Connect worked - runing your Sketch for persistand Wifi worked as well but seems not to store the data?
Trying to get the Web server running --- remains in Weiting to connect to WiFi...
Is Persisten setting still working or not supported with the modified AT firmware?

Jiri Bilek's firmware? use esp8266 Arduino core 2.7.4 or for 3+ patch the fw source with JiriBilek/ESP_ATMod@5cfdcb5

Perfect... sorry I did not find these comments, was looking for Discussions... but not the bug reports...
so afirst I did the patch and now it looks better, OTA is working if Ssrial is started and closed before OTA... okay...
Web server is also startet but after 3 refrshs the connection fails - so it looks like all 5 possible connections will be used instead reusing the second one... would it be better to stay with 2.7.4? I made the switch to 2.7.4. same behaviour...
Another thing I want to get confirmed... writing the sketch I used the board manager with generic ESP8266 mdule - do I need to adopt settings? do I need to change the flash size? I assume the Board has 32 Mbits, your script is using 2 Mbits, but there are different OTA settings available... what is best to use? First I tried with default, no I changeed to 2MB FS 1MB OTA 512 KB, but looks pretty the same
and the log is showing outo detect..

with the WebServer example?

different OTA settings available... what is best to use?

the fw requires FS, but doesn't use OTA (for fw). for a 4 MB flash any settings with some FS is OK. Just use always the same setting to preserve saved settings of the fw.

is there a way to pay your coffee with paypal?

I have PayPal for my gmail address [email protected]

Hi, with the modified Webserver from above, but I can try with your example again...
I see: my use of OTA is related to the Arduino, not to the ESP.. so not relevant

I just tried to start the debug mode... first block is with working refresh of browser, second is failing...

but the second block is OTA. and the output doesn't show a fail. UNLINK is OK.
debug slows the library down . OTA will not work reliably with debug on.
for OTA I recommend to change the baud rate for AT to 250000 baud.

Hi, I tried with debug off and 250000, and now also with 500000, no change...

MAybe I should cler ESP and write the Modiefied AT Sketch again? what is the best procedure to erease all? Or is this noit relevant when I am updating wito IDE and sketch? I am now on ESP8266 Version 2.6.4, modified Jiri Bilek's firmware , Arduino Mega 2560 Optiboot, anything else I can check?

Arduino is in a second VLAN, so I use a fake Programmer... shall I switch off the NO_OTA_PORT? -> allready tried - also no change...

thank you for the donation. I am glad that both libraries WiFiEspAT and ArduinoOTA are useful for many

Yes they are.... I am afraid there could be more using it but the first steps are really hard... I started with Arduino some weeks ago, OTA with an Ethernet shield worked fine after I found a how to... but now switching to Wifi took me another 3 days of learning... for beginners like me its also not clear that a sketch on ESP is overwriting the firmware - and the trouble started with a demo sketch (-: to understand the board and DIP settings... I will write on a little how to when my project is running. Even Jiri Bilek's Firmware is better to get started with because you do not need any seperat Firmware writer APP and can just "write a sketch"with Arduino IDE...

One warning I am getting, jus for your information:

Webserver and OTA Update - only one is working... why? #97
