I am interfacing ESP8266 with my Murata LoRa board(though not using LoRa), so let us just say I am using STM32L072CZ with ESP8266 connected on UART1(Pin9,10). I am seeing a strange behavior from STM UART.

The code being used is as below,



char cmd[]="AT+CWLAP\r\n";



int main()








This works well for the first few iterations and then fails as seen in attachment. Please help and pin point the problem and solution.
