i guess cuz missing MHI driver or USB driver, btw should GLAP(PCIe only) version never have ttyUSBx devices?
You at least do have an AT interface. What’s your OS/Kernel setup?
I’m testing on OpenWRT/Snapshot with just a minor patch in the MHI driver.

As I understand it the GLAP module would still need an AT interface for diagnostics/firmware upgrade e.t.c.
Hopefully someone at Quectel can chip in.
Perhaps there may be a way to run AT commands over QMI. None found so far.
