Hi,
I'm having some issues using OpenWrt on my Huasifei WH3000 Pro. After installing required packages for MBIM + ModemManager, I managed to configure the WWAN connection on /dev/cdc-wdm0 using LuCi.
After setting up the connection, the interface stays with the Following error:
Error: Unknown error (NO_REGISTRATION)
The modem I use is a Quectel RM500U-EA:
root@OpenWrt:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux 6.6.119 xhci-hcd xHCI Host Controller
Bus 001 Device 002: ID 05e3:0610 GenesysLogic USB2.1 Hub
Bus 002 Device 001: ID 1d6b:0003 Linux 6.6.119 xhci-hcd xHCI Host Controller
Bus 002 Device 002: ID 05e3:0626 GenesysLogic USB3.1 Hub
Bus 002 Device 003: ID 2c7c:0900 Quectel RM500U-EA
cdc-wdm0 is properly populated:
root@OpenWrt:~# ls -l /dev/cdc-wdm0
crw------- 1 root root 180, 176 Mar 28 14:22 /dev/cdc-wdm0
But mmcli doesn't seem to detect the modem (not sure if it's related):
root@OpenWrt:~# mmcli -L
No modems were found
Then I restart ModemManager service:
root@OpenWrt:~# service modemmanager restart
And after 1 or 2 minutes, the modem shows up:
root@OpenWrt:~# mmcli -L
/org/freedesktop/ModemManager1/Modem/0 [Quectel] RM500U-EA
Here we can see it stucked at disabled state:
root@OpenWrt:~# mmcli -m 0

I also tried to enable radio using mbimcli, but it times out:
root@OpenWrt:~# mbimcli --device-open-proxy --device="/dev/cdc-wdm0" --quectel-query-radio-state
error: operation failed: Transaction timed out
root@OpenWrt:~# mbimcli --device-open-proxy --device="/dev/cdc-wdm0" --quectel-set-radio-state=on
error: operation failed: Transaction timed out
The only way to disable airplane mode, is to do it using picocom (note that I don't need to restart ModemManager to run the AT commands):
root@OpenWrt:~# picocom /dev/ttyUSB2

Terminal ready
ATE1

+CFUN: 4

Then the interface connects successfully.
Any idea how to disable the airplane mode permanently? I tried to use one of the scripts in /usr/share/ModemManager/fcc-unlock.available.d as a workaround but it fails as shown above.
Thanks for any help
