Bluetooth stereo headsets and wi-fi radio streaming

I've just bought a Jabra bt620s bluetooth stereo headphones and they work great with my xda exec (using the latest qtek rom)
My only problem is when i try to stream wi-fi radio station, it cuts out every other second, im wondering if this is a common thing using other headsets and if any1 has any solutions.
thanks in advance

Hi there,
I got some moto Bt sterio headphones. Really very good quality.
I am able to stream radio to the headset with out cutting out every second. It can pause now and again but its listenable through wifi. I listen to Radio ABF and this is quite a high bit rate station....
Im listening to it right now @ 192 KBps through Blue tooth streaming perfectly......but it is through Active sync.....What prog are u using to stream>?
Try a combination of TCMP and GSplayer. See which one cuts out the least, within both progs I believe you can set your own buffer settings. See if changing this helps.
If I stream a 400 + MB movie from my PC to my Uni then have the sound coming through BT I get a similar problem with constant "jucking" and stuttering every other second. Its much better when I copy the movie to my new 1 GB sd card £18 from www.ebuyer.co.uk!!!
I remember paying over £40 for my first 64mb MMC card for my original SPV. By the end of the year we will have 2 GB for £20 I recon.......

Same problem here with i-Tech BlueBAND Bluetooth Stereo Headset. It seems to be due to some interferences between BT and WiFi connection...

Jabra bt620s and HTC Wizard

HI to all,
i just received the new jabra bt620s to run a2dp (bluetooth stereo) on my wizard. I have to say i also have a motorola ht820, with which i experience severe problems with a2dp, both with the test rom and the new rom with the "upgrade". The problem which i had with the motorola was a very annoying intermittent a2dp connection, i mean a fraction of a second missing (sometimes extending up to 1-5 seconds) every 10-50 seconds. Listening music like this is - frankly - unacceptable and i decided to change headset.
I have the jabra in action since one hour. the Jabra bt620s is simply FANTASTIC. not only it works flawlessly (i also run voice command) but a2dp is PERFECT, no interruptions. The bluetooth field is about 5m and within the range i never have interruptions. Basses are louder (larger speaker than the motorola) and the comfort is superb (but i also liked the motorola comfort). The volume, a bit weak on both headsets, can be increased by increasing the intensity on media player: however, the motorola shows evident distortions at 100% while the jabra stands beautifully and delivers indeed what you' expect. The look of the jabra is more elegant than the "princess leyla" one of the motorola.
the jabra also has some other nice features: it can be used - through USB - as headset with the windows pc, and media player can be controlled from the headset buttons.
installation on the wizard is flawless in both cases. Now i am using ROM 2.17 and the patch you find on xda-developers.
I cannot guarantee anybody that the jabra works perfectly on ANY wizard. In fact, despite all attempts with my motorola, i also noticed in this forum that other motorola users were satisfied with the a2dp. It was not my case, and i really tried everything - including switching off all the radio sources i have at home (cordless, tv relay, wifi). However, even at my workplace the motorola doesn't work, so i don't feel it is an environment problem but more the specific wizard-headset coupling. The Jabra works as expected! I have the impression both are good and genuine products by professional firms, but in my case one works and the other doesn't. FYI, i bought my motorola in Singapore and my Jabra in Germany/i wonder if different distributors sells equipment with different qualities...but i doubt it. Anyway i have no doubt where they are manufactured!
I just want to propagate my experience: if you want an a2dp headset, buy two (and sell the one you like less) or try it beforehand if you have the chance of finding a store with the material on stock...;-)
Best Regards

I like them both also. My 820 works better than my 620 when it comes to voice command. Getting the Voice Command to operate via headset,620, is hit or miss moreso than the 820. I have had both for over a month. I do use the 620 when I am in the gym or when I am not really going to use the Voice Command feature. I wish TCMP was controllable via AVRCP it would really make the headsets stand out. The sound is way better thru TCMP. I am waiting for the Nextlink Spiders to come out, next month hopefully, it is supposed to put both of these to shame.
I am running Summiter's latest ROM with extra ringers and A2DP and the sort.

i agree but...
Hi,
i fully agree with all your statements but i want to raise again the point that - with my qtek 9100 - the motorola doesn't work correctly while the jabra does!

I just received my jabra BT620s too and I love it!! I didn't have another A2DP headphones before that, but I can tell that it's well built and I find them more stylish than the Motorola BT820. The music sounds great and the phone function is well incorporated. I wish there was a easier way to start the music than from the bluetooth settings (somebody should write a small app that we could map to a button) and I'll like to use something else that WMP to play the music, like TCPMP or Pocket Player.
I'm still trying to do the same functions on my WinXP machine, but I'm unable to send the music to the headphones, even after pairing... If someone know how to do it, let me now. Is there a way to control WMP or Winamp throught bluetooth stereo headphones? By the way I use the widcomm stack on my computer.

HI Survivant,
i don't have BT on the PC, but i could connect the bt620s to the pc with the USB cable. Just push both big pads after 10 secs you are connected to the PC usb, as described in the manual. You can pause/FF from the headset, for example...

Initial A2DP findings

Using the M3100 with the itech clip S35 Headset
firstly i've been using the fit4cat tweaker which has an A2DP quality improvememt tweak - unfortunately the tweak makes the quality worse so i've tuned it off and the music quality is not too bad when playing through my car stereo. However, I need to try some decent headphnes with the unit because the ones supplied sound very tinny!
Secondly, when you first pair the device, media player plays through the headset ok. If you then go out of range, when you return the headset re-pairs ok for the phone but the media player doesn't and it plays through the loudspeaker. You have to enter BT settings and recheck the stereo music option to have the sound through the headset again. Anybody getting this with the same or other headsets?
Thirdly, I have the S35 outputting through my car stereo. When people are calling me they can hear an echo (of themselves speaking as the sound comes out through the car speakers). There is some sort of delay i suppose but this is very annoying. I'm not sure why its happening because when I tried the headset using my Sony Ericsson W800i there was no such echo!
therfore, is the echo problem an A2DP thing (as the w800i does not support it and this works ok) or is it a m3100 thing? To test this I could turn off A2DP and ry the headset again - is this possible?
any suggestions appreciated

I have the Jabra BT620s headphones and I have indentical problems.
After install all works well but as soon as you disconnect media player just plays via the phone speaker

at least you guys get it to work once. WMP never plays through my iPAQ bluetooth headset. AVRCP controls work fine though. TCPMP plays fine through the bluetooth headset as long as I pair it up before I execute TCPMP. This is exactly how it worked with my 8125.
The WMP issue is very strange and is likely yet another example of the lack of QA testing in the A2DP portion of the TyTN's implementation. I would expect that these issues will all be fixed in a subsequent TyTN ROM update.

I'm getting on ok with this
quality is pretty good both using the headset with my own sony ear buds. Vast improvement over the itech supplied ear buds.
A2DP - no skipping during normal playback and it works well - quality is not an issue through the car stereo either - not bad at all . I've even been listening to music over A2DP and running sat nav using a GPS BT receiver. A slight pause in music when GPS connects but then all runs well.
My only 2 gripes are:-
1. When you disconnect or go out of range of the headset, it reconnect perfectly with the phone application. This isn't the case with the wireless stereo. I have to enter BT settings, uncheck the wireless stereo setting, save then recheck the setting before it reconnects. Slightly annoying but accesptable (for now)
2. the echo using the headset through my car stereo. People calling me can hear themselves again (about a 0.5 second delay) through the car speakers! Just to repeat my earlier post, this does not happen with my W800i. not sure if its an A2DP problem or something else.

Similarly here, I don't seem to be able to make A2DP (and the handsfree profile, for that matter) work.
Using HTC and an Itech clip, I am able to pair the "wireless stereo" and then play music for some 10 seconds on the GS Player, after which the Wireless Stereo symbol disappears from the top bar and the connection is interrupted. I actually believe that the Itech clip is 'shut off', as I have to turn it on again.
When I try to reconnect the headset, it just won't work and the whole machine is slowed down. Only a soft reset helps.
I hope this is a ROM problem (and not mine) and it'll be fixed soon...

WMP and the Itech clip work fine for me, with the current German ROM.

a2dp issues w/th Hermes
With the CHT9000 WWE rom I had the wireless stereo drop off after about 1 minute, then I would have to reconnect. I flashed to the other dopod WWE ROM (latest) and the problem is gone....sound is comparable to my prophet. Reg tweaks suggested in other forums definetely make the sound quality worse for either ROM version. I think further updated ROM's will improve A2DP reliability (or someone may find a reg hack)...as with the prophet A2DP it just takes time.

Hi guys, I've got the vario ii and the Sony Ericsson HBH-610.
I can add the headset fine and make calls through it, but I don't know how to get the music in wmp to play through it.
If anyone has a few mins spare and could explain it for me I would be really grateful

Headsets..HBH 610...
With my CHT 9000 I use an OMIZ 5660...works great for calls and wireless stereo. I don't have any other headset to compare it to (since I only have used this brand)....I believe that if your "options" do not list wireless stereo then you can't use the A2DP function on your device, at least as it is designed to be used.
I'm not aware of a one-piece headset that supports A2DP that is available (all should have either 2 headphones or two wired ear plugs)..

THE ONLY WAY, I FIND :
I have a 590A Plantronics Bluetooth HeadSet
You must refresh Services of your iTech or your Plantronics !
Go Parameters, Bluetooth, Select your Headset, Refresh.
Then reselect services and Save !
Each time you lost the link (Bluetooth turn off or ...) you will have to Refresh,reselect and Save !
I am searching for a Solve but not find another !

I forget something else !
It is the same thing with my Bluetooth GPS (GNS).

I have a spv m3100 and jabra bt620. They both work like a dream most of the time apart from having to go into bluetooth settings each time I want to connect to the stereo headset option.
I have noticed that when in my garden or at home (a quiet environment probably) that I have excellent streaming but when I am walking around, particularly in built up areas like shopping centres, high streets, tube trains, that there is some loss in the streaming which would seem to point towards some kind of interference.
Why the wireless stereo is set as mono as standard I can't understand. I'm sure its to do with improving the streaming quality, but they are supposed to be STEREO!!! Also I set the quality to 58 instead of 48 and there was a definite loss in streaming quality so I switched back to 48.
The AVRCP also works brilliantly in WMP.
The wireless connection also plays havoc with the bluetooth stereo connection with the buffering of stereo constantly dropping. Also noticed that AVRCP wont work with TCPMP, but as there seems to be some major issues with TCPMP and the Tytn I have uninstalled it for the time being until the guys at CorePacket come up with a fix

So far A2DP has worked fine for me with my Nokia HS-12W. I have applied some registry settings and optimised my SD card and so far it has played with hardly a skip. Definitely better than my previous BA with WM5.

This is the biggest problem for me with my M3100 at the moment. I'm guessing it will only be fixed by an updated\alternative ROM(?!), any ROM's out there I could try that might get round this problem??
Thanks

This is probably headset dependent because with my Nokia HS-12W if i need to reconnect i just press the Audio button and it re-establishes the A2DP connection. No going to BT settings at all.

Interesting, can you just confirm what you mean by the Audio button. Is that just hitting 'Play' in WMP?
Thanks

No, the Nokia has a Music key (not Audio, my mistake) which switches from A2DP to the built-in radio. So if i have lost the BT connection pushing the Music key to select the Audio player will re-establish the connection and music is streamed to the headset. You will see the A2DP icon on the today screen when it has connected and get the chime in the headset.

Ok, thanks for that.
Just one last point, if the connection is lost while music is streaming, does the audio switch to the phone speaker instead??
My problem is I'll be listening to music on the subway then or some reason I'll loose the connection (interferance, low battery...whatever) and immediately music starts coming out the speaker, much to my embarrassment!
Thanks again!

Stutter Probs Streaming audio over network and playing over A2DP

First Post, Hi to all.
Hardware:
I have just purchased an SPV M3100 (HTC TyTn) and I think it's great I want to use it to play music from my MP3 collection which is shared over the LAN and output the music to my new bluetooth A2DP speakers (Accoustic Energy)
Software:
The PDA is running WM5. I have installed V-mobile Software Network Browser which adds a network folder to the system and allows me to map my Computers MP3 shared folder as a network drive on the phone (This works a treat).
I am using CorePlayer as my media player as this is the best one I've found, it plays all my music and also my divx/xvid movies.
Problem:
I can play music straight over the network using coreplayer fine from the phone (WIFI & BT both turned on), but when I connect the BT speakers I get stuttering. Occasionally it seems to work fine, but most of the time the music is really broken up.
I can play music straight off the phone and send to the BT speakers and it works great, but only if WIFI is turned off.
It seems that the phone is maybe struggling to run WIFI & A2DP simultaneously, which is a little bit annoying.
Plea For Help:
Is there ANYONE who has tried to do this on ANY PDA? If there is, was it successful or are you having similar stuttering probs?
PS. I have tried the A2DP bitpool reg hacks with no luck, and even tried the 802.11g wifi hack in case it was a wifi bandwidth problem.
If Anyone can offer any suggestions or advice I would be most greatful.
//not sure if I posted this in the correct thread, it might be better suited to accessories?

Old laptop = a2dp reciever for PPC stereo?

This may be off topic for the forum, but I'm wondering if I could throw some ideas around in the hopes that perhaps someone from here has done something similar and could offer suggestions.
I've got this old IBM thinkpad attached to my stereo system which I use as a streaming media computer for my music (obsolete laptop, but good for playing internet streams or media files on my home network over the stereo).
I very often attach my pocket pc (HTC Titan) as my music player to the stereo as well, usually using a portable a2dp receiver with a 3.5" port (i.tech r35, to be exact) to stream music wirelessly.
Problem with this is that I constantly need to charge the r35 adapter because it won't charge the battery while playing music (poor design choice).
The obvious solution, since my laptop is always hooked up anyway, would be to add a bluetooth dongle to the laptop and use it at a receiver.
I tried this, but sadly WinXP does not support the A2DP profile in its native stack, and I don't have a valid license for any of the third party ones (broadcomm, Bluesoleil, etc).
Is there a simple way to support a2dp stream receiving from this laptop? An open-source bluetooth stack perhaps?
The truth is, I don't really need *windows* on there for what I use it for, I would be open to installing a linux distro if it had a2dp support built in (and wasn't too complicated to install and use... I've got very limited linux experience).
What do you guys think?

nobody has any pointers?

Wouldnt it be easier to do via wifi? Better range and higher quality than A2DP too?

i've used my wizard to stream to my laptop before with just the native bluetooth stack on the laptop
i'm sure you could just buy a bluetooth dongle and sync it via A2DP that way

Download bluesoleil, it has an A2DP server you can use to send audio from PPC to the laptop.

Um... I'm not sure that you understood the concept here. First of all, when properly configured, a2dp is virtually indistinguishable to wired speakers when dealing with mp3 files (you lose a slight amount since it IS compressing the data, but not any more than a well encoded mp3). Second, range isn't an issue since I plan to control the music from the room I'm in (why would u want to play the music in a room far enough away that u can't hear it?).
Third, unless I haven't heard of a new Wifi audio protocol, I think what you're talking about is TOTALLY different. I stream music to my stereo from networked computers all the time, but thats not what I'm talking about here.
I use my ppc as my personal music player, and sometimes I want my playlist on the ppc to come out of the stereo system in my house. A2dp lets u do that by simply BEING IN THE SAME ROOM AS IT. I frankly don't see how WiFi would be an acceptable alternative to this since there is no audio transport support built in- its designed mostly for just networking.
I'd love to be proved wrong, so please share with me if I'm missing something here, but how would Wifi be better?
thenext1, I actually have bluesoleil, but its not registered to my device so its stuck on a 5mb trial version (5mb of info and it stops). I was thinking of something free / open source, which is why I thought about a linux option. if there is a free windows stack for A2dp, I'd love to try it...

This looks intersting I am about to try this bluesolei
What I'm looking to do is actually route calls to my laptop mic and speakers when my phone is docked in the cradle...
I'm thinking since this is the same principle that it can be accomplished?
Let me know if anyone has done this before...
it is kind of "off-topic" but i think it was relavent to post here because it deals with the same principles

It's not the same principle, A2DP is for hi-quality audio, you are trying to make the handsfree profile work.... It should work, since bluesoleil can also do that

Wow. You have got some aggression issues.
First of all, read through the entire post above and replace A2DP with WiFi and see what comes out. There is no advantage of using A2DP over Wifi if you have wifi on your phone. Set up a simple streaming server on your mobile then stream it over Wifi to your laptop. After the first configuration you run one application on your phone and press play in whichever media player you have on your laptop to start the music. Dead easy. Full quality, no reencoding or anything. Control the music from your PDA etc etc.
Not entirely sure what you are on about with the range? Wifi works perfectly if you're in the same room, what's A2DPs advantage? You dont have to stand 100 m from your stereo just because you're using wifi
Oh, and reencoded A2DP is _not_ indistinguishable from MP3s on normal speakers. Unless you mean laptop speakers. A2DP is a lossy encoding that is limited by the connection speed (and thus signal strength) which means that you have to be right next to the bluetooth receiver to get maximum quality. As you move away from the receiver the signal will drop, thus the speed will drop along with sound quality. Same thing happens with Wifi but the lowest connection speed over Wifi is still way beyond what you need to stream music at decent quality.
And.. ehm.. Both wifi and bluetooth are ways to transfer data, A2DP is just a protocol like FTP or HTTP. No magic there, Bluetooth and Wifi are basically the same thing but with different bandwidth and range capacities. In this case you'd use HTTP to transfer the music over Wifi instead of A2DP over Bluetooth, result is the same.

why isn't it the same principle?
my motorols HT820 headphones are A2DP and it has a microphone on them and i use it as a headset and to play music
...
BTW if you're looking for something free and linuxy why not use VLC over wifi
i'm almost positive they have a mobile client and it would def. be better than a2dp

I have to say I share the thread starter's frustration on this. Perhaps a little clarification is in order.
A2DP is far better suited to the purpose than a stream server on wifi in this case, because was simply designed to do exactly what Dishe is trying to do - connect an audio source to an audio sink without wires. Given the right software stack, all this should involve is a quick pairing procedure.
Streaming audio on the other hand, especially from a mobile device, is somewhat tedious - hacky at best, but certainly not "dead simple". You'd have to set up a stream server, probably third party and definitely not part of standard wifi installs. A audio streaming server on a mobile device could prove to be quite a resource hog as well. Attempting to this so in a time where bluetooth dongles (especially the made in china ones) that come with Bluesoleil go for next to nothing sounds like unnecessary fuss to me.
About a solution, I think picking up a cheap bluetooth dongle with Bluesoleil installed would be the most painless way to go. Linux and bluetooth don't exactly play nice from experience, but I've never actually tried to run an A2DP sink on it. You could do some reading on BlueZ, which is linux's standard stack and see if anyone else has had any luck.
Right now, A2DP sources are more common on PC stacks than A2DP sinks - people usually want to send audio out to a wireless headset or something instead of recieve audio - so google doesn't seem to be of much help. I'm currently trying to get it to work as well, and will test BlueSoleil within the week or so on a Windows computer and post back here if it works. Don't hold your breath, though.
