[freemangordon]

( 9,38,27) tmlind: freemangordon: i could never get the notifications to trigger on qmi, they seem to be forced to uart ts27.010 only
( 9,38,53) tmlind: sure if you figure out a way to make things work with qmi that would simplify things :)
( 9,39,51) tmlind: seems to be a modem firmware specific configuration
( 9,53,37) freemangordon: I see
( 9,54,33) tmlind: who knows, maybe the modem configuration could be updated with some commands
( 9,55,02) freemangordon: well, either ways we don;t have qmi calls working (in upstream)
( 9,55,10) freemangordon: so I will spend some time on it
( 9,56,12) tmlind: ok cool. so for now we've been mostly using qmi commands, and just kick the modem on uart pdu notifications so the qmimodem sees the event
( 9,56,18) tmlind: let me find the commit for you
( 9,57,38) freemangordon: tmlind: in the meanwhile https://git.kernel.org/pub/scm/network/ofono/ofono.git/commit/?id=8af8136f61742be963b67b88f18e85c12509e0f9, https://lore.kernel.org/all/[email protected]/ and https://lore.kernel.org/all/[email protected]/ :)
( 9,57,56) freemangordon: perhaps I should have cc-ed you
( 9,57,58) freemangordon: next time
( 9,58,58) freemangordon: I guess that should work on d4 as well
(10,01,18) tmlind: ok great
(10,01,39) tmlind: so for kicking the qmimodem on uart notifications, see mot_qmi_trigger_events()
(10,02,04) tmlind: ideally we'd find a way to re-route notifications back to the qmimodem by using some at or qmi commands..
(10,02,16) tmlind: and then plain qmimodem should just work
(10,02,28) freemangordon: and it lacks voice calls suppoer :D
(10,02,34) freemangordon: but, yeah, that's the plan
(10,03,15) freemangordon: will take a while though, I want to finish what I was doing initially before jumping to qmimodem (cpl phone applet)
(10,03,25) tmlind: and i think right now if a qmimodem data connection gets disconnected, qmimodem driver won't notice that and modem consumes extra 80 mW of power until the data connection is shut down
(10,04,00) freemangordon: and then will jump to d4 driver
(10,04,04) tmlind: so at least disconnect notification using mot_qmi_trigger_events() is currently missing and causing poor power consumption when moving around and getting disconnected by the cell network
(10,04,13) tmlind: ok
(10,04,16) freemangordon: oh
(10,04,29) freemangordon: ok, lets save that somewhere
(10,04,51) tmlind: yeah we get some 0 ending uart notfication, but should call mot_qmi_trigger_events()
(10,05,03) Pali left the room (quit: Ping timeout: 256 seconds).
(10,05,08) tmlind: so uart knows data got disconnected, qmimodem driver does not
(10,05,49) tmlind: probably easy to reproduce with some tin foil over the phone :)
(10,06,28) freemangordon: already did that when I was playing with signal strength iirc :)
(10,06,39) tmlind: hehe ok :)
(10,07,00) freemangordon: I think it is some 'enable event' command that's missing
