I have Quectel EC200UCNAB Module My problem is i am able to communicate with USB AT Port without any issues but i am not able to communicate with Main UART.

my module is EC200UCNAB and i am checking the firmware version using AT+GMR command response the version showing is EC200UCNAAR01A05M08 is this correct firmware in module?

What’s the issue with main UART?

Hi @Aditya_J
The firmware version you are using is fine, EUAB and EUAA share the firmware of EUAA, did you install the uart serial port driver? If so please give me your email and I will send it to you.
