OsmoDevCon 2019 registration

by Harald Welte

Dear fellow Osmocom developers, I'm a bit surprised to notice that not more people have signed up for OsmoDevCon 2019. I guess it was mostly an oversight when the date was originally announced, and not a lack of interest? ;) All details about the event are available at the related wiki page at: https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019 Please enter your name at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019#Requested in case you would like to attend. Registering early allows proper planning. Thanks! Looking forward to meeting old and new Osmocom developers in April 2019.

Loading HelloWorld firmware in Motorolla C118

by haiderali91

Hello, I am trying to load helloworld firmware into my phone (Motorolla C118) using sysmocom CP2102-25 cable by executing the following command sudo ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/compal_e88/hello_world.compalram.bin But I am not getting any response on pressing power button briefly. The command keeps on executing without any message. What can be the issue and how to deal with/debug this issue. I have also attached a cu terminal by using following command. $ sudo cu -l /dev/ttyUSB0 -s 115200 The cu terminal displays this message on pressing power button. ��A@ftmtoolerror

MT6260 Datasheet available

by Craig Comstock

Hi all, Somoene shared what looks like a quite useful datasheet for MT6260 at the kosagi/fernvale forum. I have downloaded it and looked a bit and it looks very helpful. I have linked to it in the wiki at: https://osmocom.org/projects/baseband/wiki/MT6260 Original post at kosagi forum: https://www.kosagi.com/forums/viewtopic.php?pid=3313#p3313 I hope to rejoin my effort on porting layer1 firmware to fernvale in about 1 month. Cheers, Craig

Re: Voice calls over Virtual Um

by Vadim Yanitskiy

Hello Andreas, sorry for late response. > I set up a network with Virtual Um and multiple OsmocomBB > phones. They register, they can send and receive SMS > and I wanted to try voice calls. First of all, it should be noted that voice support in OsmocomBB is experimental and undocumented. I have been working on GAPK back-end integration, and it seems you've already found some branch, but I would recommend to use 'fixeria/audio' instead of 'fixeria/mncc'. > calls can be established, but GAPK is never initialized and > again, I never see voice data appearing as an MNCC message. Please check out the configuration examples [1] for mobile app. There you should find the new 'audio' section, where: io-target hardware means that audio I/O (by default) should be handled by the hardware (i.e. by Calypso phone). GAPK is not enabled by default. In order to use GAPK based back-end, use 'gapk': io-target gapk It probably makes sense to rename 'gapk' to 'alsa', because at the moment 'gapk' enables both voice playback and capture using the audio system of the host that running mobile. > I never seem to receive a GSM_TCHF_FRAME-message on > the MNCC socket. This can also be configured: io-target socket In this case GAPK is not used, and all TCH frames are being forwarded to the MNCC handler 'as-is'. See [2] commit description for details. Please also note that audio I/O target != MNCC handler, that actually implements the Call Control logic. See [3] for details. [1] https://git.osmocom.org/osmocom-bb/tree/doc/examples/mobile/default.cfg?h=f… [2] https://git.osmocom.org/osmocom-bb/commit/?h=fixeria/audio&id=bdb2854503afd… [3] https://git.osmocom.org/osmocom-bb/commit/?h=fixeria/audio&id=22edbf3f846b1… With best regards, Vadim Yanitskiy.

Voice calls over Virtual Um

by Andreas Galauner

Hi, I set up a network with Virtual Um and multiple OsmocomBB phones. They register, they can send and receive SMS and I wanted to try voice calls. I looked around and found a repository [1] with an MNCC example application which sends voice samples. Calls are established and can be picked up, but on the other end, but I never seem to receive a GSM_TCHF_FRAME-message on the MNCC socket. I then checked out the fixeria/mncc branch [2] which includes GAPK integration which can use ALSA devices for audio, because that's what I need anyway at some point for my project I'm working on. Again, calls can be established, but GAPK is never initialized and again, I never see voice data appearing as an MNCC message. The GAPK audio backend is supposed to be initialized [3] when a CHANNEL MODE MODIFY message is received from the network. I never see the network request a channel mode modify though. I don't know enough about GSM to find out if that message is always supposed to be sent when a call is established or not. Did anybody ever transport audio with two OsmocomBB instances over the Virtual Um interface? Thanks, - Andy [1]: https://github.com/GerardPinto/call-control-mncc-sap [2]: https://git.osmocom.org/osmocom-bb/log/?h=fixeria/mncc [3]: https://git.osmocom.org/osmocom-bb/tree/src/host/layer23/src/mobile/gsm48_r…
