Quectel USB AT port is not recognized

Asier · February 20, 2024, 5:04pm

Hello,

I have a Quectel_UMTS&LTE_EVB_Kit with a BG95-M3 connected to it. I installed the driver “Quectel_LTE&5G_Windows_USB_Driver_V2.1” in my Windows 11 PC and I am using the USB connector. However, when I go into Device_Manager the USB AT port is not recognized. See the attached image below.

Is there any problem with the driver? How can I solve this?

Thanks and regards,

Asier

Does the Quectel USB Modem Exist? It is also the AT port.

Hello Bean,

Yes it does exist.

However, I still do not know how to send the AT commands. What is the COM port I should use?

Regards,

Asier

Hello again,

Just found it, the AT commands are working.

Thanks for the tip.

Yes. You could send AT via the Quectel USB Modem #2.
