I'm checking whether I can get the Quectel BG95 modem to work with QMI
mode. I'm currently using ModemManager 1.18.2 and libqmi 1.30.2.
ModemManager doesn't manage to advance the state machine past the
"enabled" state. This is despite the modem actually already being
registered and attached to the network:
+CGPADDR: 1,**REDACTED IP**
I noticed a few QMI protocol errors in the log (complete log at
3046:<warn> [1637917459.156274] [modem0] couldn't load supported bands:
Couldn't parse the list of supported bands
3218:<warn> [1637917459.178727] [modem0] couldn't query SIM slots: QMI

3649:<warn> [1637917459.264097] [modem0/sim0] couldn't load list of

numbers: Couldn't get MSISDN: QMI protocol error (16): 'NotProvisioned'
3938:<warn> [1637917459.404641] [modem0] failed checking whether
autoconnect is disabled or not: QMI protocol error (94): 'NotSupported'
The last one in particular seems to be related to the problem at hand.
What exactly does "autoconnect" mean in this context? Is there a way to
deal with a modem that does indeed have autoconnect enabled?
