<div dir="auto">More info on these disconects. It seems that the better the signal and faster the speed results in faster and more frequent disconects. Around 5 to 10 min. When the speeds and signal is worse it lasts around 30 to 40 min. When no data is being transferred it stays up indefinitely. </div><div class="gmail_extra"> <div class="gmail_quote">On Feb 9, 2017 3:18 AM, "Aleksander Morgado" <<a href="mailto:aleksander@aleksander.es">aleksander@aleksander.es</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On Thu, Feb 9, 2017 at 4:52 AM, Mark Wahlert <<a href="mailto:mark.wahlert@gmail.com">mark.wahlert@gmail.com</a>> wrote: >> No. In fact it's almost the exact opposite.

Those logs don't say much I think, it's basically the modem reporting that there is a (network initiated?) disconnection. so MM reports that as well: [/dev/cdc-wdm0] Received message... >>>>>> RAW: >>>>>> length = 80 >>>>>> data = 07:00:00:80:50:00:00:00:00:00:00:00:01:00:00:00:00:00:00:00:A2:89:CC:33:BC:BB:8B:4F:B6:B0:13:3E:C2:AA:E6:DF:0C:00:00:00:24:00:00:00:00:00:00:00:03:00:00:00:00:00:00:00:00:00:00:00:7E:5E:2A:7E:4E:6F:72:72:73:6B:65:6E:7E:5E:2A:7E:00:00:00:00 [/dev/cdc-wdm0] Received message (translated)... >>>>>> Header: >>>>>> length = 80 >>>>>> type = indicate-status (0x80000007) >>>>>> transaction = 0 >>>>>> Fragment header: >>>>>> total = 1 >>>>>> current = 0 >>>>>> Contents: >>>>>> service = 'basic-connect' (a289cc33-bcbb-8b4f-b6b0-133ec2aae6df) >>>>>> cid = 'connect' (0x0000000c) <debug> [1486196931.947257] [mm-broadband-modem-mbim.c:2252] device_notification_cb(): Received notification (service 'basic-connect', command 'connect') <debug> [1486196931.947393] [mm-broadband-modem-mbim.c:2009] basic_connect_notification_connect(): Session ID '0' was deactivated. <debug> [1486196931.947476] [mm-broadband-modem-mbim.c:1972] bearer_list_report_disconnected_status(): Bearer '/org/freedesktop/ModemManager1/Bearer/0' was disconnected. <debug> [1486196931.947573] [mm-port.c:94] mm_port_set_connected(): (wwan0): port now disconnected <info> [1486196931.947749] [mm-iface-modem.c:1431] __iface_modem_update_state_internal(): Modem /org/freedesktop/ModemManager1/Modem/0: state changed (connected -> registered) Just to make sure there isn't any more info, I manually decoded all the fields in that indication: 00:00:00:00 session id --> 0 03:00:00:00 activation state -> deactivated 00:00:00:00 voice call state -> none 00:00:00:00 ip type --> default 7E:5E:2A:7E:4E:6F:72:72:73:6B:65:6E:7E:5E:2A:7E context type -> Internet 00:00:00:00 nw error -> unset Someone should add "printable" message contents to libmbim debug logs... -- Aleksander <a href="https://aleksander.es" rel="noreferrer" target="_blank">https://aleksander.es</a> </blockquote></div></div>
