I have a prog which tests interrupt timer with software reset..it runs perfectly ok.
I have the exact same code but with the addition of a wifi connect...this gives a meditation error and core dump at the point of interrupt/reset....
does anybody know if there is an incompatibility issue between wifi and interrupt timer/reset?
I have searched and found many issues with interrupt reset from the early days of esp32 but none that seem relevant.
no wifi
