Sierra Wireless EM7455

[Stefan Armbruster]

Aleksander, I've just reinstalled qmi-over-mbim branches (both libmbim
and libqmi) using ./configure --prefix=/usr; make; sudo make install
and still getting the same result:

# qmicli -v -d /dev/cdc-wdm0 --dms-set-fcc-authentication

error: couldn't create client for the 'dms' service: CID allocation
failed in the CTL client: Transaction timed out

The above was run with modemmanager stopped beforehand. Running the
same command while modemmanager is running gives a slightly different
error message at the end:

[06 Mai 2016, 09:38:22] -Warning ** Error reading from istream: Die
Ressource ist zur Zeit nicht verfügbar
error: couldn't create client for the 'dms' service: CID allocation

The German part means: resource is currently not available.

Is there any kind of reset/init command that I should send before that one?

Cheers,
Stefan
