Hi,
Im dealing with a Sierra Wireless MC7354. Im testing it on coverage limits
(removing antenna) on UTMS. In normal operation, RRC_STATE moves between
CELL_DCH, CELL_FACH and CONNECTING while ModemManager.Modem.state keeps
CONNECTED. Sometimes the modem reach DISCONNECTED state in spite of the
fact that ModemManager.Modem.state keeps CONNECTED too. In this state, Modem
doesnt reconnect anymore until I make disable/enable call.
ModemManager: 1.5.990
Libqmi: 1.14.0
