IoT Modules LTE Standard Module

Hi,

I’m working whit EG21 (on my embedded device via USB) module under YOCTO OS. I’ve integrated the driver into the kernel for wwan interface and seems correct because I see the device under
/sys/kernel/debug/usb/devices
I build and run, on the embedded device, the quectel-CM tool so to test the qwan interface, but seems it doesn’t working well, below the output

before to run the tool, via minicon, I’ve set the SIM PIN.

What I’ve forgott ? Any idea?

Thanks

Hi @ratataplam
May I ask which version of the quectel-CM tool you are using?
