Hello all,
I am using Quectel RG255C-GL with version RG255CGLABR01A08M4G_A0.001.A0.001. I am facing issues with connectivity as the module is not establishing a PDU session or obtaining an IP address.
Below are the logs:
When I start the UE, the following logs appear, but there is no wwan interface:
[ 671.464682] usb 1-1.1: new high-speed USB device number 5 using xhci_hcd
[ 671.566501] usb 1-1.1: New USB device found, idVendor=2c7c, idProduct=0316, bcdDevice= 5.15
[ 671.566534] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[ 671.566564] usb 1-1.1: Manufacturer: Quectel
[ 671.566577] usb 1-1.1: SerialNumber: 4b9b150c
When using the command lsusb -t, the output is:
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M

After manually forcing /dev/cdc-wdm, two interfaces appear:
wwan0, wwan1
However, the module is still not establishing a PDU session.
Some extra information from the UE side after running start script:
./start.sh
