How to set the specified ttyUSB number to run quectel-CM

IoT Modules 5G Module
1

Hello,

I am working with two RG530 modules connected to the same Ubuntu 22.04 computer.

  • The first RG530 is running on a commercial 5G network and appears as /dev/ttyUSB0,1,2,3.
  • The second RG530 is running on an srsRAN network and appears as /dev/ttyUSB4,5,6,7.

I need to use ./quectel-CM in my python script, but I would like to specify which ttyUSB device it should use.

Is there an option (for example, via ./quectel-CM -?) that allows me to explicitly select the desired ttyUSB number?

Thank you for your help!

Dear @Guoying
Sorry, we don’t have parameter to specific port.

For such Qualcomm Chip module, it would use the qmi channel by default, it will not use the AT channel.
