Hey Pete,
I started a new project (other auth token) with no widgets in the app with the same code as in the first post and it worked. So I decided to remove the timers and virtual pins from my orginal project and it worked.
Sounds to me like you have some underlying issues that re showing themselves as various random and seemingly unrelated symptoms.
I still think that the AT firmware you flashed to the ESP chip may be the issue.
Do you have any other boards that you could use for testing?
Pete.
Which AT firmware do you recommend?
Do you know what firmware shipped with the board? Did you try that one out before overwriting it with the current version?
Pete.
Yeah, that one didn’t function… I flashed the latest esp non os sdk thinf
Hello Pete
For good communication and help, this topic can be closed.
The Robotdyn Mega 2560 + Wifi R3 is currently working stable for 48 hours without any Buffer overflows. Still don’t know the correct cause of the buffer overflow error.
Thanks for the help!
