Is modemmanager on VOXL1?
-
I'm struggling to understand how the modem link is managed/maintained in VOXL; so I have a few questions...
As best I can tell, modemmanager is not used, true?
I see the sierra.py script runs at startup (assuming voxl-configure-modem has been run prior) polling for /dev/ttyUSB2. That's fine for startup, but what about runtime... Is anything monitoring the link status?
What facility/service is actually using qmi_wwan0.c in VOXL?
Finally...
After voxl-build completes, I can see several different qmi_wwan0.c files
under the workspace. Which one is actually used?Thanks for your patience!

@Ed-Sutter That is correct, modemmanager is not used.
As you can see in the patch here: https://gitlab.com/voxl-public/system-image-build/meta-voxl/-/blob/master/recipes-kernel/linux-quic/files/qmi_wwan2.patch
The path to the
qmi_wwan.cfile that is being modified / used isdrivers/net/usb/qmi_wwan.c
