Quectel USB AT port not found

Hello,

I am new to Quectel LTE module. I am using BG95 Quectel LTE Evaluation board(UMTS/LTE module). In order to support the serial communication, I had to install the USB drivers. So I had installed “Quectel LTE&5G Windows USB_Driver_V2.1” driver. After the installation, I could see Quectel USB DM port, Quectel USB NMEA port but not USB AT port in the device manager. It would be great help if anyone guide me through installation. I have attached the image of device manager section.

Thank you

Hello,

BG95 doesn’t have AT port and it’s discarded in chipset. For AT communication, you can use Quectel USB Modem port.
