Quectel BG96

[Aleksander Morgado]

Hey,

> I have tested Quectel BG96 (DevKit) with libqmi 1.16.5 and it seems to work, made some additions in qmi_wwan.c and option.c, modelled it after EC21/EC25. The chipset is MDM9206. I have no RF yet, so cannot test data connection, but I will get back on that.

Yes, this is likely your setup. I assume you're running qmicli 1.18
against libqmi 1.16, or something like that, because the path where
you installed qmicli is in $PATH (e.g. /usr/local/bin) but the path
where you installed libqmi-glib isn't automatically included in the
library load paths.

If you didn't use any specifi --prefix when running configure, you
probably installed everything in /usr/local, so just try:

$ LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin qmicli ...

Will you be sending these patches to the linux kernel mailing list yourself?

Cheers!
