Hello .
I’m developping an program for esp8266-01 to upload data into cayenne platform. I’m using arduino IDE and cayenne mqtt libraries from github.
All is running well but evey 30 minutes the Esp8266 reboots. I’ve removed all code except wifi connection and cayenne begin and loop functions to isolate the issue.
I’d appreciate any suggestion or clue.
.
can you share the code you are using.
This is the code (reduced to isolate the issue)
***You’ll find just cayenne mqtt and server management functions. Please dont take care of variables definition . ***
I’ve tested both with and without sending client requests/cayenne requests. In both cases the ESP reboots every 30’ aprox. (I’ve tested during 10 hours) .

there are too much going on your code. if you are able to get output on serial monitor then add #define CAYENNE_DEBUG to see what is causing the disconnect.
At a quick glance everything looks ok to me. Usually resets and connection issues are due to delays that are too long or loops that are stuck in an infinite loop. You don’t have either of those so as Shramik said you should enable debug to get some more info as to what is happening when the device crashes.
