Hello all,
Once again, I'm a bit out of my depth and hoping for some guidance.
I'm trying to use a Fibocom L850-GL. My modem is a custom build with an imx6ul and i'm connecting the L850 through an m.2 slot on the board. My openwrt is also based off of 19.07.
I can see it and communicate with it initially just fine. It creates a device in /dev and I can see a network wwan0 is created, this tells me im at least starting out okay.
Here is its entry in /sys/kernel/debug/usb/devices

and here's the output of mmcli -m 0
. You can see that a modem is created and it's pointing to the correct device .

while that's all fine and dandy, trying to enable the modem with mmcli -m0 --enable
does not work. I will get an error telling me :
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: Cannot power-up: sotware radio switch is OFF'
Now I have not been able to find any reference to any software switch in the documentation for the modem itself, nor have I had any luck playing around with mbimcli
, qmicli
, or umbim
I also want to note that there is no status error in the response message I get from using mbimcli -p -d /dev/cdc-wdm0 --set-radio-state=on
, it just seems to do nothing.
At this point, I'm pretty much out of ideas on what to do next.
Any help is greatly appreciated!
