I am getting exception 29 and it crashes the ESP12F. I am sending HTTP Request every 15-30ms to ESP. It sometimes crashes after thousand request and sometimes crashes after few hundred request. My project requires HTTP Request to be sent every 15-30ms but I have used Millis in order to receive request and perform some function every 100ms in order to avoid any incomplete close connection or overflow. I have increased the CPU Frequency from 80Mhz to 120Mhz, but it still crashes.
I have attached the ESP Exception stack decoder result.
