Hey Alex
To answer my own questions.
I have been back through the build config of ModemManager.
Checking the timestamps of the mm daemon and libraries the build order was incorrect, looks like libqmi and mbim was built after MM so it wasn’t picked up as a dependency when running the configure.
Reconfigured MM and its now picked up
Features:
udev: yes
policykit: no
mbim: yes
qmi: yes
When checking the location-status now with mmcli its reported correctly;
# mmcli -L
/org/freedesktop/ModemManager1/Modem/0 [Sierra Wireless, Incorporated] MC7430
#
# mmcli -m 0 -e
successfully enabled the modem
# mmcli -m 0 --location-status
--------------------------------
Location | capabilities: 3gpp-lac-ci, gps-raw, gps-nmea, agps-msa, agps-msb
| enabled: 3gpp-lac-ci
| signals: no
--------------------------------
GPS | refresh rate: 30 seconds
| supported assistance: xtra
| assistance servers: http://xtrapath2.izatcloud.net/xtra3grc.bin
| http://xtrapath3.izatcloud.net/xtra3grc.bin
| http://xtrapath1.izatcloud.net/xtra3grc.bin
Thank you.
