Dylan Van Assche	ef94492b30	gnss: handle locked SIM ModemManager Location service is only available after SIM unlock and network registration. Track service separately to avoid an assert error and crashes. GNSS assistance data is uploaded when the service becomes available.	2021-08-12 11:19:45 +02:00
Dylan Van Assche	75570e45da	gpio: extend softsleep wake time 50ms is way to short for the Quectel firmware to react, increase to 200ms	2021-08-12 11:19:21 +02:00

Dylan Van Assche	10ec1119fb	at: fast/poweroff is only available in newer firmware versions Do not retry the AT command of the fast/poweroff setting as it may not be supported by the firmware	2021-08-11 12:58:06 +02:00
Dylan Van Assche	898c0dc79c	config: synchronize with modem-power We cannot assume default factory values if other drivers change them	2021-08-11 12:56:42 +02:00
Arnaud Ferraris	6b3bc5660a	Merge branch 'gps-support' into 'master' gnss: GNSS assistance support Closes mobian1/issues#253 and #2 See merge request mobian1/devices/eg25-manager!15	2021-08-10 20:58:26 +00:00
Arnaud Ferraris	128483354b	udev: remove reset quirk It seems to work just fine with MM's quick suspend/resume.	2021-08-10 22:27:07 +02:00
Dylan Van Assche	9cfe782f74	gnss: add GNSS assistance support Automatically fetch the GNSS assistance data from the Web to heavily reduce the time to acquire a GNSS lock by uploading the assistance data to the modem. This feature is optional and can be disabled in the configuration as people may prefer to not download the assistance data from the Quectel/Qualcomm servers. Also configure the GNSS engine to optimize the performance and power consumption.	2021-06-21 07:54:39 +02:00
Dylan Van Assche	5da7c88fc4	at: allow custom callbacks for AT command response processing	2021-06-21 07:53:44 +02:00
Dylan Van Assche	dac50e34eb	at: log expected result before setting it to NULL Otherwise the log contains NULL instead of the expected value, making it hard to debug	2021-06-21 07:53:39 +02:00
Dylan Van Assche	9646e0e8df	at: make next_at_command, send_at_command, process_at_result, and append_at_command public methods Allows other modules to send AT commands as well	2021-06-21 07:53:33 +02:00
Dylan Van Assche	9c4a934a51	at: g_free doesn't require NULL checking From the docs: If mem is NULL it simply returns, so there is no need to check mem against NULL before calling this function.	2021-06-21 07:53:28 +02:00
Arnaud Ferraris	f2593b62b1	Merge branch 'soft-sleep-runtime' into 'master' at: wake only when sending AT commands Closes #12 See merge request mobian1/devices/eg25-manager!21	2021-06-17 09:35:39 +00:00

Natanael Copa	63ba5e2d60	Fix parallel build issue Tell meson that the generated gdbofono headers are needed at compile time. fixes https://gitlab.com/mobian1/devices/eg25-manager/-/issues/14	2021-06-03 17:51:57 +02:00
Dylan Van Assche	e690e2a17d	at: wake only when sending AT commands Allow the modem to enter soft sleep when we don't talk to the modem using AT commands. This was already the case in suspend, but not during runtime. By only waking the modem from soft sleep when we need to send an AT command, we can save some power.	2021-05-23 20:13:16 +02:00
Arnaud Ferraris	64145acbae	Merge branch 'mm-cleanup' into 'master' mm-iface: clean out modem_iface if mm disappears See merge request mobian1/devices/eg25-manager!17	2021-04-15 15:48:02 +00:00
Bhushan Shah	705950bb39	mm-iface: clean out modem_iface if mm disappears otherwise we will be stuck in state where restarting of mm will not reset the modem_iface and it will loop through hard resetting modem	2021-04-15 11:08:06 +05:30
