MC7455 location support

[Karoly Pados]

Hello,

I have a MC7455 form Sierra Wireless. It is working fine for data communication, but ModemManager doesn't seem to be able to recognize the locations services (GPS and A-GPS) provided by the modem. 

mmcli -m 0 --location-status

/org/freedesktop/ModemManager1/Modem/0
  ----------------------------
  Location |   capabilities: '3gpp-lac-ci'
           |        enabled: '3gpp-lac-ci'
           |        signals: 'no'

If I start ModemManager with the --debug flag and then issue AT-commands using --command by hand, I can get a GPS fix and retrieve the location using raw AT commands. (This also means that in my case there is no need to unlock location services using a password.)

I read on this list that the modem needs to be in QMI-mode for MM to support location data. I think this is already the case because when I start MM in debug mode I can see it is using QMI to communicate.

Is there anything else I can do or need to check to make location data in MM working? Or any way I can help to implement support for it?

My software:
# uname -a
Linux a13-olinuxino 4.9.21 #2 SMP Mon Apr 10 10:29:48 CEST 2017 armv7l GNU/Linux
# ModemManager --version
ModemManager 1.6.2
...
# qmicli --version
qmicli 1.16.0
...


Thank you for your help, greetings,

Károly Pados
