[maemo-developers] Bluetooth Headset: first steps
Hi, I've summarized some steps I took to get my bluetooth headset working with my 770 on this wiki page: http://maemo.org/maemowiki/BluetoothHeadsetHacking Thanks to the help of Johan and Ville who provided a new bluetooth firmware blob, it is possible to record audio using a bluetooth headset. So far, I didn't manage to playback audio via the headset, but maybe somebody else succeeds. Also, there's currently no application (I know of) that uses ALSA devices on the 770, so besides the sheer joy of having something on the 770 you don't have on the 800, it doesn't add much value. regards -- jochen ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Hi, Johan Hedberg wrote: AFAIK, the procedure of changing the SCO routing on the TI chip requires a proprietary TI HCI command. I'm not sure we can publish it since it's documented in TI docs which have quite strict publication restrictions. I had a closer look at the driver for the chipset. The firmware appears to be just a sequence of TI HCI commands which is dumped to the chip. Could you please release a modified firmware image that changes the SCO routing? The additional commands wouldn't be any more public like the rest of the hci commands in the firmware file, so I guess that should be ok with legal. btw, there's a nice collection of commands used in such bluetooth-scripts available at: http://wiki.xda-developers.com/index.php?pagename=UniversalBluetooth regards -- jochen ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

I'm not sure we can publish it since it's documented in TI docs which have quite strict publication restrictions. afaik there's a bluetooth script for some embedded devices using the same chip (bfr6150) which does something with the audio routing. these scripts are available online, and openembedded has a parser for it. probably these proprietary commands are available already, and we just have to try it out :) regards -- jochen ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Martin * resulting audio is not very loud and occasionally makes a pop sound on high-volume input. 64-bit version runs without these problems. This are the problems I also noticed with libsbc from sf.net. Where can I find the 64-bit Version? I have actually been tinkering again with the 32-bit version--I think dynamic compression could mostly work around the problems. In any case I will create a separate sbc64 cvs module and announce it on the lists.

[maemo-developers] Bluetooth Headset Support - Status update?
Referring back to this thread: http://www.gossamer-threads.com/lists/maemo/developers/12526?nohighlight=1#12526 Tommi asked that this subject be brought up again after the next release (which I presume to have been OS2007) so it isn't forgotten. Is it possible to get an updated position on Bluetooth Headset support on both 770 and N800? It's crazy that after all this time with VoIP support that these devices still don't have Bluetooth Headset and A2DP support. The 770 and N800 are crying out for BT headset support! :) Neil ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

It's crazy that after all this time with VoIP support that these devices still don't have Bluetooth Headset and A2DP support. The 770 and N800 are crying out for BT headset support! :) I'm pretty sure that you could write an A2DP music player that worked on the 770 without any help from Nokia. It wouldn't be nicely integrated, but it should work. I tested an app awhile ago, and got music coming out of my headset, it was just not real time - a second of music, 5 seconds silence, etc. The reason for this is that it needed to transcode the music into a different CODEC, for which there was no integer version available. If you were to, say, just store all your music in that format, transcoding as you uploaded to the 770, then no problem. Headset / handfree support requires SCO sockets, which are a deeper, driver level thing. Many Bluetooth chipsets handle SCO connections in special ways - they do things like feed the audio out a separate interface so you can hook up a microphone and speaker directly, rather than pushing the audio through the CPU. Thus, there's often more config and poking needed to get the chipset into the right mode. Does anybody know if the N800 uses the same Bluetooth chipset as the 770?

Hi, On Sat, Jan 13, 2007, Gopi Flaherty wrote: Does anybody know if the N800 uses the same Bluetooth chipset as the 770? 770 has a TI chip while the N800 uses a CSR chip (BlueCore4). To use SCO audio using existing bluez software you need to get the chip into SCO over HCI mode (I think both devices are by default in SCO over PCM mode, i.e. try to transfer audio over a direct HW link between the bluetooth controller and the DSP). You'll probably find the procedure for manipulating the SCO routing on the CSR chip somewhere on bluez related web pages (maybe the available SW even does it automatically) since CSR dongles are quite popular. I don't know the exact procedure my self. AFAIK, the procedure of changing the SCO routing on the TI chip requires a proprietary TI HCI command. I'm not sure we can publish it since it's documented in TI docs which have quite strict publication restrictions. I.e. this still needs some internal investigation. However, even with the command, neither the chip firmware nor the driver have been tested with SCO so there is guarantee that it'd work. We are currently working on integrating SCO support (Headset Profile to be exact) nicely with the new and still experimental D-Bus based service infrastructure of bluez and the rest of the internet tablet software. The plan is to use the DSP routing instead of the HCI routing, which should improve latencies. So, you should see support for this in some SW update in the future. Unfortunately I can't give any exact schedule currently, but you can follow the progress quite well simply by looking at what's going on with bluez (i.e. CVS commits mailing list discussions). You'll probably see some preliminary support in the next release of bluez-utils (version 3.9). Oh, and it's possible that A2DP support will come along at some point too since from the bluez side the plan is to integrate it to the same audio daemon as HSP/HFP. However, from our (Nokia) perspective it hasn't been given the same priority as HSP so in the short term support for it will be very unofficial if it exists at all. Some ideas (a very early draft) for the planed architecture can be found at the bluetooth-alsa pages: http://bluetooth-alsa.sourceforge.net/future.html Johan ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Thus, there's often more config and poking needed to get the chipset into the right mode. Does anybody know if the N800 uses the same Bluetooth chipset as the 770? it's a bluecore4. you could use bccmd to route its audio to hci. if you do mess around with bccmd, i'd recommend you make all changes to ram and just don't even bother with the permanent settings. it would be so sad to brick the bluetooth adapter in a new n800. brad * resulting audio is not very loud and occasionally makes a pop sound on high-volume input. 64-bit version runs without these problems. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

I've seen some nice Nokia Bluetooth Headsets while shopping this afternoon, would be great if Nokia Headsets worked with Nokia 770 :).

Re: [maemo-developers] Bluetooth headset - not really working?
Ralph Is there a bandwidth problem, or just people being silly with the design? There is a bandwidth problem. High-quality audio is compressed on the fly before transmission. We will probably be able to build in the delay to the video player so it slips the video stream a bit. gstreamer may even have a way to specify in the codec plugin how much latency it introduces. Some of these problems could be fixed if a new audio spec was written that required the extended data rate of bluetooth 2.0 and left out compression. The a2dp spec says nothing about duplex high-quality audio, but there's no reason a headset couldn't try to connect back to the source node on an independent connection when it starts receiving audio. That's basically how the AVRCP connection works. Brad ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-developers] Bluetooth headset - not really working?
BTW, did anyone notice the following lines in the dmesg output on the 770 in the 51-13 firmware? [4.037261] Bluetooth: L2CAP ver 2.7 [4.041015] Bluetooth: L2CAP socket layer initialized [4.046356] Bluetooth: SCO (Voice Link) ver 0.4 [4.051147] Bluetooth: SCO socket layer initialized [4.056365] Bluetooth: RFCOMM ver 1.5 [4.060272] Bluetooth: RFCOMM socket layer initialized [4.065704] Bluetooth: RFCOMM TTY layer initialized [4.070861] Bluetooth: BNEP (Ethernet Emulation) ver 1.2 [4.076477] Bluetooth: HIDP (Human Interface Emulation) ver 1.1 It mentions SCO. I'm not sure if that means anything or if this was present in the older versions of the firmware, I just thought it was interesting. Also, a few lines above the Bluetooth stuff, you can find: [3.814697] Advanced Linux Sound Architecture Driver Version 1.0.9rc2 (Thu Mar 24 10:33:39 2005 UTC). [3.828033] usbcore: registered new driver snd-usb-audio [3.833709] ALSA device list: [3.836822] #0: Dummy 1 USB Audio? Anyway, I sort of get the feeling that Nokia is keeping so quiet about this mostly because this is something they want to release in the 2006 firmware and they most probably don't want anyone stealing their thunder and releasing a fully-working VoIP package for the 770 before that. With Asterisk and chan_bluetooth ported to the device, the 770 could become the ultimate VoIP phone. Any clues yet from Nokia? :).

Sorry, I didn't made that clear enough. I was refering to the following said in http://article.gmane.org/gmane.linux.bluez.devel/6729 by Marcel Holtmann: The Nokia 770 is using a TI chip and basically nobody of us has real experiences with these chips. I have seen them in an iPAQ and now the 770, but that's it. Do you think Nokia is willing to donate some of the TI development kits to BlueZ? Especially the SCO and eSCO stuff needs a lot of testing and I would prefer to do it with an i386 or x86_86 based system. And the answer to that in http://article.gmane.org/gmane.linux.bluez.devel/6748 by Ville Tervo from Nokia: I'll try to arrange something. low-latency voice-quality mono audio uses a special transport (SCO) and is delivered from the bluetooth chip either over the regular data connection to the cpu (HCI) or it is connected to dedicated audio/analog hardware (PCM). The HCI formatting and negotiation differs from chip to chip and the linux driver is only complete for CSR chipsets. Thanks for the explanation - SCO is exectly what I need then. a2dp specifies one-way high-quality, traditionally stereo, audio. It is delivered over an L2CAP socket so linux can send and receive this audio with any bluetooth chip that has even the most basic support. So that is used for bluetooth stereo earphones to listen to e.g. CD music? We know what has to be done for a2dp. The SCO stuff is what I would like to see help from Nokia on. I would hope they can help us with the HCI interaction with the SCO transport since that gives us the most generic control over the audio stream. Thanks for that details!

So the Bluetooth stack, according to this message, now supports handling of SCO traffic (kernel modules sco.ko). But this does not mean that the HCI driver for the specific Bluetooth module in use can handle it (kernel modules hci_* and friends). Those are two distinct things...

[maemo-developers] Bluetooth headset - not really working?
Hello everyone, This is a resend, I am not sure the message ever made it to the list. If it did, please disregard it. The error I received from the Postfix server at the previous send attempt is at the bottom of this email. -- I have spent the past 2 days trying to get a JABRA 250 Bluetooth headset to work with my Nokia 770.I followedthe instructions at http://maemo.org/maemowiki/BluetoothHeadset and everything went fine, up to the point described in the Wiki. I have also compiled the alsa-utils package to get the aplay utility and tried to play some sound. Nokia770-45:~# ./aplay -D plughw:Headset /media/mmc1/xp.wav Playing WAVE '/media/mmc1/xp.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Stereo This command never returns unless I press ctrl-c and kill it. There seems to be some sort of connection established, but all I hear in the headset is some hissing and popping, I have no idea how to describe it. It's definitely not silence, but it has no connection to the content of the WAV being played either. Here's what btsco says during all this: Nokia770-45:~# btsco -v 00:07:A4:03:33:33 1btsco v0.4cDevice is 1:0Voice setting: 0x0060RFCOMM channel 1 connectedNokia770-45:~# btsco -v 00:07:A4:03:33:33 1btsco v0.4cDevice is 1:0Voice setting: 0x0060 RFCOMM channel 1 connectedspeaker volume: 0 mic volume: 0i/o needed: connecting sco...connected SCO channelDone setting sco fdrecieved AT+VGS=11Sending up speaker change 11speaker volume: 11 mic volume: 1 driver is not in usedisconnected SCO channel The last 2 lines appear after I press CTRL-C to kill aplay and then CTRL-C to kill btsco. The same hissing/popping sounds are heard when using the hstest tool from bluez-utils (this one plays the sound directly over Bluetooth as far as I can tell). And also the same type of sound is heard when using chan_bluetooth ( http://www.crazygreek.co.uk/content/chan_bluetooth) with the ported version of Asterisk on the Nokia 770. This seems to have been reported before (not for the 770): http://sourceforge.net/tracker/index.php?func=detailaid=1273754group_id=116589atid=678258 . However, the solution pskey mapsco 0 only seems to work with CSR Bluetooth chips, and the 770 has a TI chip. If anyone's interested, I'm attaching the output of a hcidump during all this. Has anyone been successful in establishing SCO connections between a Nokia 770 and a Bluetooth headset? According to this: http://article.gmane.org/gmane.linux.bluez.devel/6728 , Nokia is working on Bluetooth headset support. Could anyone at Nokia give us an update?
