I have Quectel EC200UCNAB Module , i am reading the firmware version using AT command using GSM AT port i am showing that EC200UCNAAR01A05M08 , is this correct firmware version?
I am not able to communicate with Main UART.
Hello, The AT command you used should indeed provide the correct firmware version of your EC200UCNAB module. If you’re unable to communicate with the Main UART, this could be a configuration or wiring issue, or possibly a problem with the module itself. Double-check your wiring and UART settings (baud rate, data bits, parity, and stop bits). If the problem persists, contact Quectel support with the specifics of your issue.
Thanks for your reply
Could you please share the latest firmware of EC200UCNAB
