MBIM_CID_DEVICE_SERVICE_SUBSCRIBE_LIST support

[Jose, Shijo]

Okay thanks.

> Is the dbus-daemon running?

Yes, dbus-daemon is running with the 'system' option. ModemManager process seems to be running too.

However when I restart ModemManager from the shell per the instructions provided in - 
www.freedesktop.org/wiki/Software/ModemManager/Debugging/, I see the log message "[5337]: <info>  ModemManager is shut down)" but the process seems to be running.

I am looking to monitor -

Solicited and Unsolicited:
SIM status (MBIM_CID_SUBSCRIBER_READY_STATUS)
Connection / PDP context information (MBIM_CID_PROVISIONED_CONTEXTS?)
Registration state (MBIM_REGISTRATION_STATE_INFO)
IP configuration (MBIM_CID_IP_CONFIGURATION)

Solicited:
Packet statistics (MBIM_CID_PACKET_STATISTICS)

How do I check if ModemManager is receiving these unsolicited events? I did not find a method to do this in the Modem/Manager objects.

Hey,

Yes, or some other custom process that keeps an MBIM session open and is able to receive unsolicited messages. ModemManager works very well in this case, so I'd just suggest that.

I built ModemManager, libqmi and libmbim packages for openwrt a while ago, see:

Is the dbus-daemon running?

This is implicit in ModemManager. ModemManager registers for the indications automatically. Which indications are you wanting to monitor?
