Hi Team,

I need to send some data to server over HTTP after every 30 mins. To do this, tried using hardware timers (took the help from the given example "timer_group.c").
There are several task running in my code.Getting error after adding timer code with ISR. Backtraced the error as below.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

Could you please help me understand what is this error saying??? How to solve this??

Thanks

Pretty hard to say... smells like memory corruption, but that's about all I can make out.
