GSM Response Issue

Hello Everyone,
Please help me I am new to the forum. I’m using the ESP32 controller and M95 GSM module. I’m connecting the esp32 to M95 via the UART port. The issue is when I sent the AT command from esp32 to GSM, it communicate to the GSM module but the esp32 simply received the cmd that I have sent. When I tried the GSM module with Q Navigator via the Main port using RS232, it respond to my AT cmd’s but when I connect to the esp32 it simply received the cmd not the response of that command.

Guys, please help me to do this

Dear Saran
Make sure you have sent \r\n(carriage return and line feed) after the AT command
For Ex: “AT\r\n”
