Hi @4IceG,

i'm playing with a CPE that supporto only PCIE module, so I got an RM520N-GLAP (no the AA version). Using Quectel MHI driver, is not possible to see all informations.

I've edited 3ginfo.sh and getdevicevendorproduct() function adding this entry into the case statement:

        'mhi_DUN'*)
            devpath=$(find /sys/devices -name "$devname" -type d 2>/dev/null | head -1)
            target_dir=${devpath%/*/*/*}
            V=$(cat "$target_dir/vendor")
            D=$(cat "$target_dir/device")
            echo "pci/${V/0x/}${D/0x/}"
	    ;;

/dev/mhi_DUN is the AT port exposed by Quectel MHI driver. Then I've created under the modem/pci folder the usual file with VIDPID, for Quectel RM520N (using the usb file) only the last part was changed to display working protocol:

# Protocol
# DRIVER=QMI_WWAN & DRIVER=CDC_MBIM
if [ -d "/sys/class/mhi_uci_q" ]; then
    if ls /sys/class/mhi_uci_q/mhi_QMI0 > /dev/null 2>&1; then
        PROTO="qmi"
    elif ls /sys/class/mhi_uci_q/mhi_MBIM* > /dev/null 2>&1; then
        PROTO="mbim"
    else
        PROTO="unknown"
    fi
fi

and it's working:

Let me know if you want a PR

Thanks!

Hi @stich86 ,
You can make a PR if you want 😏, but I don't know when the new package/repository update will be. Right now, I'm focusing on preparing the new package.

Hi @stich86 ,
Do you have working packages in OpenWrt to support this modem in pcie mode?

PCIE MHI Driver, Quectel SPRD PCIE, Quectel QMI WWAN, Quectel GobiNet?

hi @4IceG,

regarding the driver, I've compiled the one from Quectel, and for the WWAN part, i've used quectel-cm and relative packages that @SuperKali has sent to me

@SuperKali can you help @4IceG on this part?

Thanks!
