Voice calls working on N900 (*) (was Re: N900 modem support in 3.18-rc1)
Hi!
(*) for low values of working.
Ok, so I got voice on n900 to work on 3.19-n900 tree.. Quality of incoming
voice is reasonable, quality of outgoing voice not so, I was told.
So, you need patched kernel (pali's n900 tree) ofono etc, plus I'm
using ofone python script to control the modem, plus you need
libcmtspeechdata. I have this version:
commit 7f8f3ce357513e4849e1bf6d657980a514529c1a
Author: Kai Vehmanen
Date: Tue Mar 8 13:46:48 2011 +0200
cmtspeech_msgs: fix compiler warning
Add parenthesis to make the code more readable and to kill a
compiler
warning.
Signed-off-by: Kai Vehmanen
Plus, apply the patch below. I could not get configure (etc) to work
for me, so I build it by hand. cmtspeech_ofono_test can then be used
to route the voice calls (if you feed it with audio data, see the
"run" script).
What is missing:
* right setup of mixers. (I was actually running audio data to my
desktop for some tests). What commandline tools can be used to set up
mixers? I'm using "alsamixer", but it has text ui...
* passing audio data using pipes is really a hack... and periodically
discarding audio data is certainly not a good idea.
Good luck,
Pavel

Ok, so realtime audio does not work due to some pulseaudio problems, but I was able to record a (silent) call and then replay it with pacat --rate 4000 ../../../pulseaudio2.raw on my PC. I have yet to do some testing on the microphone side. I'm using Debian 7 as a a base, and I suggest nfsroot. It seems that libcmtspeechdata + pulseaudio-module-cmtspeech-n9xx is enough to get calls to work. Now. I could not get configure on these packages to work, so I hard-coded build scripts (mkit). You'll need to symlink resulting .so to pulseaudio directory (see /my/pulseaudio-module-cmtspeech-n9xx/src/cmtspeech/mkit). I leave binaries in, since this is non-trivial to compile. Some memory allocation stuff was missing. I faked it; it seems it is not needed in the first call. untar in the root directory of n900. Reset n900, no need to log in into console, connect using ssh -X root@n900. Then go to /my/tui/ofone. Run "./run" -- that should start pulseaudio. Run "./ofone", hit "lowlevel: online", hit "contacts", enter phone number you want to call, hit the number, it should start dialing. Wait a while, hit "lowlevel: hangup". Now you should have: /my/pulseaudio2.raw you can play with pacat above, and /my/pulseaudio.log.*, which contains stuff that needs to be fixed.

Very old but still it is there, with the kernel part maintained. Userspace was based on QTopia in 2008. I don't maintain that part anymore though.

But there are two things I'd like to understand, first: a) how did Mer people solve this? Or did they just ship nokia binaries? b) do we really need those DSP algorithms? Can we just take data from microphone and send it down the GSM line, and take data from GSM line and put it to the speaker? If it will not work in the speakerphone mode, I can live with that... It should somehow work in normal-phone mode, and be definitely feasible with wired handsfree, no?

Aha, so CONFIG_CMT is the same thing as CONFIG_NOKIA_NODEM? Ok, will disable that. Speech... if you'd have version I could test, I'll happily do that.

Thanks! mh seems I actually missed to make 1 the default value. I will prepare a patch for that. I assume, that the example ofono commands work for you now? > Do you have an example client that can talk to ofonod? I have not yet played with userland stuff. You could try telepathy-ring, which integrates the ofono into the telepathy framework. > What is needed to get voice calls to work? There's still a kernel driver missing in mainline for exchanging voice data between the modem and the cpu (called cmt-speech). BTW the CMT driver should be removed from your kernel tree; its a deprecated variant of mainline's nokia-modem driver. Thus I guess the cmt-speech driver, which is available in your kernel tree, is not properly integrated into the changes I did during mainlining the other modem related drivers. -- Sebastian signature.asc Description: Digital signature
