hi, i have started ESP12-E to work with the GSM module, in this when i was running the it should be reset automatically when some messages will receives,... then it reset and restarted from first so the function is not completed,,....so, please suggest me how to disable the watchdog timer,..... when i run the program the error will be like this///.........

Soft WDT reset

        <<<stack<<<

so, please suggest me how to disable the watchdog timer and controlling of stack overflow in the esp12-e module

You are using any gms library or Your own functions for communication with gsm module?
Probably some functions waiting too long for response from gsm module and this is a reason of WDT reset.
You must search for "while loop" functions inside Your code(or gsm library) and insert yield(); inside.

P.S. Your stack without full code is useless.

[BharathTatikonda]

yahh, i am using gsm libraries and i have also used the yield(); in while loops, it will ok means some what reduces the reset functioning but at some times the esp will going to reset,.... i want to modify that purely.....................

[BharathTatikonda]

please tell me how to manage this reset one and stackover flow completely,..............

[reaper7]

Please install ESPExceptionDecoder
howto:
https://github.com/me-no-dev/EspExceptionDecoder

[BharathTatikonda]

ok i will try and then contect with u

[BharathTatikonda]

after installing, i want to include in my program or i want to run in my controller or just save in to my library section...........

You can't disable the watchdog completely, you have to fix the code to call yield().

[BharathTatikonda]

ooh what is the main function of yield(): and where i should use the yield(); funtions

[WereCatf]

yield() does some background-stuff that you don't have to know the specifics of, but calling it periodically keeps the watchdog-timer happy. If you have long while-loops or for-loops or other sections of code that take a long time to run then those sections will have to also call yield() every now and then in order not to trigger watchdog.

[BharathTatikonda]

ok what about in the if-else statements..............

[BharathTatikonda]

but probably in my code sometimes getting the complete actions but in sometimes the esp will be going to reset,..... i want to maintain the complete actions at everytime,,...how it is possible?,,,,..

[WereCatf]

Like I said, use yield() in any sections of code that may take a long time to run. It's up to you to know what sections take a long time to run and which ones don't.

[BharathTatikonda]

Ok how much time the watchdog timer will going to be reset the
microcontroller............

One suggestion to get info about your ESP when itgoing wrong
set up the terminal speed at 74880 and restart ESP.
You may get different messages to help your diagnostic.

it can be a problem of power connect battery which can supply sufficient amount of power with no voltage sage
