Fibocom L850-GL hangs upon connect.
I have been given a Fibocom L850-GL that seems to be stuck in NCM mode. As I have not had any luck changing the mode back to MBIM: ModemManager[25270]: [1533696762.104669] (ttyACM0): --> 'AT+GTUSBMODE?' ModemManager[25270]: [1533696762.121517] (ttyACM0): <-- '+CME ERROR: 4' ModemManager[25270]: [1533696831.512880] (ttyACM0): --> 'AT+GTUSBMODE=2' ModemManager[25270]: [1533696831.530829] (ttyACM0): <-- '+CME ERROR: 4' I figured I would try to see how it works under the latest version of ModemManager, but as soon as you try to actually connect to the internet, the serial port locks up. Now, given the state of this modem, it may have nothing to do with ModemManager. Since it may possibly or this may assist in adding support for these Intel XMM based chipsets, I have collected all the information I could think of to make it available to you guys, including debug logs and bus trees.

Also, I can create a temporary linux install on a junk USB drive and provide you with remote ssh access to the machine if someone wants to have full access and do whatever they want. The broadband plan is unlimited, so I'm not at all worried bandwidth use. I also decided to compile ModemManager from the git master branch, those results are at the end of the page.

[PATCH 1/2] broadband-modem-mbim: check if modem implements MBIM_CID_PCO
Being a part of a series that adds PCO support for MBIM modems that
implement the MBIM_CID_PCO extension, this patch issues a
MBIM_CID_DEVICE_SERVICES query during the modem initialization to check
if a modem implements MBIM_CID_PCO. If the modem does, ModemManager will
subscribe to MBIM_CID_PCO notifications to get PCO updates.

We will need to indicate whether the received PCO is partial or complete, so I'll go with something like an array of struct of (uint32 + boolean + byte array), i.e. a(ubay). I'm planning to do the following: 1. introduce the new Pco property under Modem3gpp interface 2. set it up for modems supporting MBIM_CID_PCO 3. migrate the altair-lte plugin to use the Pco property 4. migrate Chromium OS to use the Pco property instead of the SubscriptionState property 5. remove the SubscriptionState property from Modem3gpp -- this is an MM API break, so a version bump will be needed Does that sound like a plan? > Dan ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel

Yeah I'd vote for byte array eg "a(iay)" (eg array of struct of integer
+ byte array).

Once that logic is in place, we would need a new "simcom" plugin (there is none right now), which creates a new MMBroadbandModemSimcom that implements the voice interface and subclasses the specific command. The asynccommand could just be something like: gboolean (* setup_audio) ( MMIfaceModemVoice *self, GAsyncReadyCallback callback, gpointer user_data); gboolean (* setup_audio_finish) ( MMIfaceModemVoice *self, GAsyncResult *res, GError **error); It's a bit of work to set it up, but that is how we're able to support multiple different modems of very different kinds, by providing common logic (e.g. in the interface implementations) that may be subclassed differently by the different plugins. -- Aleksander https://aleksander.es ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
Adding AT commands to activate call audio over USB endpoint
Hi there,
We're using a SIMCom SIM7100 modem which has the ability to exchange
call audio data over a USB serial endpoint⁰. To enable this, the modem
needs an AT command after the call has connected, AT+CPCMREG=1, and a
command after call has disconnected, AT+CPCMREG=0.
Not knowing the internals of ModemManager too well, I'm wondering if
anyone could advise on an appropriate way to add these AT commands for
our particular modem?
Thanks,
Bob
