Hi Dan,
thanks for your answer.
I compiled libqmi-1.12.6-r0.1.cortexa9hf_vfp_neon.rpm (notice that it
is an older version, it was just simpler on my environment) with the
change you proposed. After that, the command seems to work:
# qmicli -d /dev/cdc-wdm0 --dms-get-operating-mode
[/dev/cdc-wdm0] Operating mode retrieved:
Mode: 'online'
HW restricted: 'no'
So is the problem in the modem firmware reporting an older DMS that
what it is really using, or is it in libqmi?
However, ModemManager still does not work because of the other message
(I recompiled it against the patched libqmi library):
ModemManager[710]: <warn> couldn't load Supported Bands: 'QMI
operation failed: Cannot send message: QMI service 'dms' version '1.3'
required, got version '1.0''
ModemManager[710]: <warn> Modem couldn't be initialized: Couldn't
check unlock status: Couldn't get SIM lock status after 6 retries
ModemManager[710]: <info> Modem: state changed (unknown -> failed)
Will this allow a similar fix?
