Hi All

I would like to know if any user has used a Quectel module with a microcontroller(e.g. SAMD21J18A) with communications via USB?

I am updating my PCB, and for a higher data rate, I would like to use USB instead of UART?

Has anyone had any experience?

My concern is connecting my microcontroller directly to BG95 via USB, but would also like to use the USB to connect to my PC for debugging and firmware updates.

Has anyone been able to do both at the same time?

Dear doshi,

To send AT from MCU to the BG95 module , we can use MainUART and usb-modem port both , for the detail rate , Pls refer to the below docs ;
