2025-04-13broadband-modem-qmi: Enable Cell BroadcastGuido Günther
For QMI we have an extra QMI request so use that to make sure receiving messages is actually enabled. Closes: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1325 Signed-off-by: Guido Günther <agx@sigxcpu.org>
2025-04-13broadband-modem-qmi: Add support for loading channelsGuido Günther
This allows to retrive the list of configured Cell Broadcast channels. Closes: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1325 Signed-off-by: Guido Günther <agx@sigxcpu.org>
2025-04-13broadband-modem-qmi: Add support for setting channelsGuido Günther
This allows to receive Cell Broadcast messages in the specified channel range on SDM670 based devices (X12 modem) and SDM845 (X20 modem) without any AT ports (like the OnePlus 6/6T and Google Pixel 3a).

2025-04-13broadband-modem-qmi: Add initial interface bitsGuido Günther
This allows to receive Cell Broadcast messages. Tested with single part CBMs only as my setup currently only allows for these. Helps: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1325 Signed-off-by: Guido Günther <agx@sigxcpu.org>
2025-04-12modem-helpers: fix checking of CDMA/EVDO access technologyDan Williams
Missing ! for strncmp() meant the test was backwards and would erroneously report 1xRTT and EVDOr0 when those access technologies were not in use. Signed-off-by: Dan Williams <dan@ioncontrol.co>
2025-04-09modem-helpers-qmi: better handle no supported modesDan Williams
Dell Snapdragon X62 before FCC Unlock reports no radio interfaces from QMI and no device capabilities from MBIM. Instead of asserting in mm_filter_supported_modes() when called from mm_supported_modes_from_qmi_supported_modes_context() gracefully handle the lack of supported modes.

2025-04-01broadband-modem-mbim: consistently handle custom data classesDan Williams
Consistently interpret the modem's reported custom data class when loading current mode, supported mode, supported capabilities, setting current mode, and current access technology. Normalize the data class to include any custom data class immediately after reading it from any MBIM message. De-normalize it when sending back to the modem when setting current modes so the modem receives MBIM_DATA_CLASS_CUSTOM for the custom mode.

2025-03-28modem: Allow to set current channel listGuido Günther
This adds support for setting the channels to override the boot up modem defaults: ``` busctl --system call org.freedesktop.ModemManager1 /org/freedesktop/ModemManager1/Modem/0 org.freedesktop.ModemManager1.Modem.CellBroadcast SetChannels 'a(uu)' 1 0 9999 busctl --system get-property org.freedesktop.ModemManager1 /org/freedesktop/ModemManager1/Modem/0 org.freedesktop.ModemManager1.Modem.CellBroadcast Channels a(uu) 1 0 9999 ``` Closes: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/934 Signed-off-by: Guido Günther <agx@sigxcpu.org>
2025-03-28modem-helpers: Add helpers to parse channel listsGuido Günther
`CSCB` has the form ``` CSCB: [0|1],"<channel-list>","<data-coding-scheme>" ``` If the first parameter is `0` this specifies the accepted types if `1` it specifies rejected. So far seen in the wild were CSCB strings with accepted types only and a coding scheme of "" so this is what we handle for the moment. Signed-off-by: Guido Günther <agx@sigxcpu.org>
2025-03-27broadband-modem: detect modem modes with +CEREG and +C5GREGDan Williams
Some AT-based modems like the Quectel Unisoc-based RM500U don't support the older AT commands we used to detect modes like AT*CNTI=2 and AT+WS46. Add support for detecting 4G and 5G with generic commands too. Fixes: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/786 Signed-off-by: Dan Williams <dan@ioncontrol.co>

2025-03-27port-probe: allow per-port ID_MM_TTY_AT_PROBE_TRIES tag for custom number of ↵Dan Williams
AT probes For modems that need more time to respond to AT port probes (like some Telit devices, and Cinterion-based Telit MV31/MV32) allow a custom number of AT probe tries on a per-port basis for generic probing, or plugins that opt into this functionality.

2025-03-23broadband-modem,iface-modem: don't treat SIM unlocks as hot-swapsDan Williams
If the old IMSI was unavailable because the SIM was locked, but now is available because the SIM was unlocked, don't treat the SIM properties change as a hotswap that may trigger dropping and re-probing the modem. Signed-off-by: Dan Williams <dan@ioncontrol.co>

2025-03-09port-probe: ensure port is open for all plugin AT probesDan Williams
If multiple plugins are selected for probing a modem with AT probes, earlier plugins may only request some probes but not all. When those probes complete successfully, subsequent plugins won't re-do the probes that were already completed, but jump to ones that haven't yet been done. For example, plugin A may request only AT probes but plugin B may request AT, AT_PRODUCT, and AT_VENDOR. Plugin B will start with AT_PRODUCT probes because plugin A already completed the AT probe. The code in probe_step() only opened the serial port for the AT probe, I guess assuming that all AT-type probes would be done in sequence. But in the above scenario they are not. Instead, make sure the port is opened for all AT style probes that have not yet been executed.

2025-03-06broadband-modem,cli: slightly bump 3GPP scan timeout; add some cli dbus ↵Dan Williams
timeout slack Add some mmcli D-Bus timeout slack, making them slightly higher than the ModemManager internal timeout, to ensure the cli doesn't time out the D-Bus call when MM succeeds. For 3GPP scan, some modems appear to have internal 5 minute timeouts, so ensure MM doesn't time out right before the modem returns results: ModemManager[282578]: <dbg> [1741054422.321400] [ttyUSB2/at] --> 'AT+COPS=?<CR>' ModemManager[282578]: <wrn> [1741054722.247806] [modem1] failed scanning networks: Serial command timed out ModemManager[282578]: <dbg> [1741054724.119770] [ttyUSB2/at] <-- '<CR><LF>+COPS: (1,"T-Mobile","T-Mobile","310260",0),,(0,1,2,3,4),(0,1,2)<CR><LF><CR><LF>OK<CR><LF>' Signed-off-by: Dan Williams <dan@ioncontrol.co>

2025-03-03broadband-modem-qmi: implement UE mode get/setRobert Marko
Instead of relying on getting/setting the UE mode via AT +CEMODE command which on Quectel RM520N (And I assume other QMI based modems) only allows getting the value and not setting one it has special AT commands for CS/PS and voice/data centric values. So lets instead use the QMI Get/Set System Selection Preference TLV which offers service domain and usage domain preference info so we can use those to get/set the 3GPP TS 24.301 UE mode values.

2025-01-23broadband-modem-qmi: separate "system info" and "serving system" indications ↵Valentin Blot
registration Some modems succeed on enabling "system info" and disabling "serving system" in one transaction, even though they don't support "system info". This commit separates the two: first, try to enable "system info", and if it succeeds then disable "serving system".
2025-01-22suspend: support logind not sending PrepareForSleep(true)Arnav Singh
elogind sends PrepareForSleep(false) when resuming but doesn't necessarily send PrepareForSleep(true) when sleeping. This means we didn't necessarily drop our previous inhibitor when it's time to take a new one. So instead of asserting that we dropped our previous inhibitor, just reuse it.
