How to stop receive data in this code? or How to stop a get char? I used Interrupt to scan WiFi Information. I need only SSID. To input a buffer (Ring or FIFO) but it keeps bringing inform.

I want to send AT+CWLAP commands and put only WiFi names (excluding commands and addresses) in the array to display five on the board. Please recommend me how to use it. Also, we analyzed the pattern. Please tell me how to parse.

What Can I do for solve this error? I refer to this GitHub! https://github.com/jrmejiaa/ESP8266 char *arg[CountOfParameter]; <-- this part makes error

How to use function in main.c I want to make function about operate state. using interrupt! Plz check my main code. and check my error. Error[Pe065]: expected a ";

How can I communicate wifi between the stm32h board and esp8266? I want to send a command to scan the network on the board with esp8266 and show the scan list on the PC through the serial monitor. Using the AT command. Is it possible?
