I've noticed a situation today where MM isn't periodically retrieving the signal quality. I can't be 100% sure, but I think it's when I have NetworkManager *automatically* bringing up a connection on reboot - sometimes it does start up retrieval ok, but a few times I've seen the problem. It doesn't *seem* to happen when I bring the NM connection up manually later. Note: this is with BEARER_CONNECTION_MONITOR_TIMEOUT lengthened to 30 (see other post today) - perhaps there's some state machine timings tripping over each other.
When it's ok the log shows [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (enabled -> registered) [src/mm-iface-modem.c:1357] periodic_signal_quality_check_enable(): Periodic signal quality checks enabled (interval = 3s) Searching the log for those state changes in the failing case just has [1494597460.115274] [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem: state changed (unknown -> disabled) [1494597460.175753] [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (disabled -> enabling) [1494597464.099723] [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (enabling -> enabled) [1494597467.717644] [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (enabled -> searching) [1494597474.130612] [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (searching -> connecting) [1494597474.378795] [src/mm-iface-modem.c:1433] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connecting -> connected) i.e. Nowhere is it indicating to/from registered state. (ref. line 1459: "If we go to registered state (from unregistered), setup signal quality and access technologies periodic retrieval") Any thoughts on where to dig into it next ? _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
