I've got a problem that I'd like to know if anyone else is experiencing.
I am running TomTom using a bluetooth gps receiver (instructions found on this site to get the damn thing to work in the first place, much appreciated). When this is all I am doing, everything is great, really fast, smooth. As I do a lot of long journeys, I notice that the position update starts slowing down the further I go, but this is still fine.
When I turn on my headset, I start to get a serious lag between my true position and where TomTom is reporting I am (I know which one to trust though, so I don't turn off the motorway a mile too late :wink: ). The starts slight, but then gets really stupid really quickly, resulting in the map being a mile or more out after a minute or two.
I have scoured this and other sites to see if anyone else is getting this problem and have so far found nothing. I have reverted to using a wire until I can get this solved.
The sound ports through to the headset fine, I can make calls, voice command works (most of the time). The headset is a BlueTrek G2, the GPS receiver I am not sure of as it came with no make or model number from eBay.
Could it be a memory issue? I generally have about 15MB program memory free. TT does drop out every once in a while but not in any pattern, whereas the lag issue always happens as soon as I connect the headset. Could it be the BT devices are operating on the same frequency (I have no idea if this is a rubbish suggestion, just something I thought of)
Does anyone know about this? Any suggestions greatly appreciated. In the meantime, I will be tied to my phone while driving.
TIA!

Even though it looksl ike no one is looking at this I found another topic for this question.

Cheers anyway!
Hi I'm new to the site, i had read a lot post about upgrading roms from different companys, i read people describe how good the a2dp quilty is, but the problems comes, i first upgraded the rom to T-Mobile , then i found there are a high pitch nosie, at first, i though it was just my earphone, after i changed it, it still the same, then i upgrade to the QTEK rom, the nosie still comes, the nosie comes as the singer start to sing!!! it makes my so dizzy, i had try to link my BT to my PC, but they sound much different! no nosie plus clearer sound!
the second problem is that when a phone call-in, the ringtone goes via BT rather than built-in speaker???
the third problem is if you set ur BT as both hands free/set and wireless stero, during a connected phone call, if you press any button on the dial pad, all the sound will gone, but the phone is still connected, i found this problem when i using my voice mail?!
also after i update to the non-O2 rom, my phone is no longer accept any MMS, i already config all the setting from O2, is just that i don't have my MMS acount appear on my mail box. i also try the .cab setting file too!
My A2DP BT is i-Tech S35
ROM Version: 1.30.77WWE (QTEK)
Radio Version: 1.09.00 (QTEK)
ExtROM Version: 1.13.188 WWE (O2)
Many Thanks!!!
Was it just me than having this problem???
- I've not the first problem.
- I've the second problem
- I never experienced third problem

Click on the above link , download the file and run it on your phone, do not alter any of the options, just click next on everything it will fix your MMS problem
thx a ur advice coff... but it still doesn't work, plus i starting to think that the nosie might cause by my s35, due to the campasility.. (sorry can't spell)
Hi MicmiC901,
Yes, it probably is something "locally" with your phone/headset/area/etc, since I also have same experience as asci, meaning;
1. NO, don't have that problem
2. YES, I have same issue (to me this is actually OK, since when headset is connected, I WANT it to only ring in the headset)
3. NO, never experienced this problem
I use the latest Qtek ROM with AKU2 and A2DP, but have never experienced that high-frequent-noise-issue you mention with any other of the A2DP ROMs on my JasJar (TMobile Germany ROM, a custom-ROM from the forums).
so RonnyGydar, which bt headset u using @ the moment? i just try with my friends logitech bt headphone, it get worse than my i.tech, sound get Stuttering , so i think i better change a new bt, would u recommand moto ht-820?
Hi MicmiC901,
Sorry the veeery slow response...but now I have even one more BT Stereo headset...so then you get the "bonus" of even more info in my reply!
I have 3 BT Stereo Headsets, and here is a short summary of experience of them all.
HP BT Stereo Headphones (same HW as the Logitech ones as I understand).
Sound is good, clear, OK bass. Nothing exceptional, but I was very pleased with them. Sound could be a bit higher at the highest volume...if you plan to use then in noisy environments...but not really an issue...since they are quite loud.
Motorola HS820
Soundwise (clarity and bass) very simmilar to the HP ones...can't point my finger on any differences. But they seem actually a little less loud than the HP ones...so with these I struggeled to hear Podcasts when I sat on a bus going through tunnels. The HP headphones are slightly louder, I think.
Bonus of these are the excellent batterylife and miniUSB plug...plus the HP ones do not have a microphone, so the HP ones are only for music. So I would easily chose the Motorola's before the HP headphones.
One minus for me with the Motorola's are that they hurt my ears after a couple of hours of use. ...that at lack of "powerfull" bass, got me to look at the i-Tech BluePRO's...
i-Tech BluePRO
These have very good bass (and they sure look like they should have it too...pretty big earmufflers...with these, you look like you are working at a construction site or something, but the clarity of the sound is actually worse than HP and Motorola...they sound a bit fuzzy.
...but I still use these all the time...mainly for two reasons. One is the excellent bass (I like to listen to techno and trance...and then bass is important, the other is that they isolate outside sounds (due to the enormous padding), so I can have the sound as low as I prefer...and STILL hear all my music without disturbance from other sounds in the environment (like sitting on the bus in a tunnel, or at a noise Gym).
It also seems that there is quite a bit difference in how the different manufacturers implement BT profiles.
My Motorola and i-Tech BluePRO have problems with "Pause/Resume"-button on headset when used with my JasJar (Pause works, but not resume...or opposite...not sure which it was, dont have the headsets with me today)...but the HP ones does not (I tested them a couple of times, and the HP headphones worked all the time)!?
Re-connection after a time without use seems also to vary a bit. The Motorola I can turn off/on the headset, and they reconnect automatically to my JasJar. The i-Tech BluePRO's I must choose re-connect in "Bluetooth settings" on my JasJar every time I want to use them.
The "famous" "lag-issue" everybody experiences I experience with all my headphones in some situations...and it does not seem any better or worse among the headsets. It seems to also be affected by general radio disturbance, since I have a lot of problems with lag at work, but no problems at all at the Gym (which is good for me...since that is the place I am most happy with having my wireless headphones), and some issues at home.
Hope this was of any help!
actually i have the problem micmic is talking about.. it happened when i upgraded my wiz to a newer rom to get the a2dp function. eventually i do not have a bt.stereo -headset yet.. (coming in about 2 weeks) but i have the issues with the sound. it's almost like a bad bitrate or something? ..wierd it is since i remains even if i downgrade my rom. =/
Hi epluribus and MicmiC901,
Is the "stuttering" you both mentioning the same as I call "occational lag"?
IF it is...it you should certainly not have it when you do the following test;
1. Reset your JasJar/Universal (to clean memmory completely)
2. Started listening to music over headset with...
3. The Universal lying on the desk in front of you completely still 50cm from your face
4. You sitting completely still
5. No WiFi on close to you.
...this test is completely overkill...but if it STILL stutters in that "controlled scenario"...well then it must be something different with your Universal or headset HW. Cause I can walk around with my JasJar (also in areas I know there are 5-6 WiFi connections active...like my appartment), and even put the JasJar on the table and walk 5-10 meters away from it...and have no or at least nothing more than an "occational stutter"/"lag".
It seems to be two major factors affecting this "stuttering"/"lag" (from my experiences at least...I have used A2DP a lot with my Universal...couple of hours every day);
1. Universal struggling outputting(RAM/CPU...or both!?)
One help here is to apply the registry "A2DP priority" fix (found it in the forums here).
Another is to close all programs before using it (I usually do not do this...I usually only do it in hindsight when I get the problem).
2. Signal between Universal and headset struggling (obstructions between Universal and headset, WiFi nearby, so forth)
I for example get this problem if I put my Universal in my trouser pocket (I know, I must have big pockets, and walk around, I get stuttering/lag occationally. If I then take it out, and hold it in my hand farily still when I walk...no stuttering. I have found, that when I walk, it is OK to have it in my backpack/rugsack...then for some reason it very rearly stutters...so I usually do that.
But when I walk of the bus at work, and walk into the "campus" of my workplace, which is cramped with radiotransmitters (is norways largest Telecom company)...I get a lot of stuttering, and need to take it out of backpack, and hold it in my hand, at it gets a lot better.
In short: A2DP with the Universal works, but is sensitive to disturbance/obstructions/moving around...and to make it worse, it is also sometimes dependant of the Universal itself struggling with CPU/RAM.
I have BTW had the exact same problems before with Qtek2020 and Qtek9090 (which I got hold of some "A2DP patches", when I had those devices). ...but I really had a LOT more stuttering with those two...so much so, that I never used A2DP with them on a daily basis.
...so it can seem that HTC is getting slightly better on each new device...?
Hope this info can be of some use!
...but it might not...if my assumption at the beginning here is wrong, and your "stuttering"-issue is something completely different than the "lag"-issue I talk about!?
iam currently using latest rom from dopod and motorola 820, although the two earpiece have sounds it is only mono, can someone help to make it stereo? o recomend what rom to use, thanks
In order to have stereo audio on a Bluetooth device, you need a profile called A2DP, which is currently only supported by the latest Qtek Universal ROM at the moment:
ftp://xda:[email protected]_Updates/UNI_QTEK_13077_176_10900_WWE.exe
Dopod has not released a ROM supporting A2DP yet.
thanks for the help, God bless
No problem. Do let us know whether it works well or not.
it works, i have stereo sound, but need improvements, in a song the bluetoth stops 3 to 4 times when playing, the player dont stop its the motorola 820 that stops several times.
I did come across a post with a patch for the A2DP flaw the other day. It's somewhere on this site - do a search and see if you're lucky.
Found it: http://forum.xda-developers.com/viewtopic.php?t=46811&highlight=universal+a2dp
It worked for me for a little while so try it.
Hi,
I have used A2DP a lot with my JasJar the last 4-5 months, and had written a summary of my experiences with this "lag/stuttering"-issue in another thread here...I have copied the most essential of that text below...might be usefull info for you;
-----------------------------------------------------------------------------------

So you can not totally get rid of the problem...but you can do a lot to minimize it...I almost never experience it now...except in the campus-area at work that is.
I have BTW had the exact same problems before with Qtek 2020 and Qtek9090 (which I got hold of some "A2DP patches", when I had those devices). ...but I really had a LOT more stuttering with those two...so much so, that I never used A2DP with them on a daily basis.
-----------------------------------------------------------------------------------
I also wrote a short post on my experiences with the different stereo headsets I have...yes, they actually act a little bit different it seems (regarding resume/pause button, and how easy/automatic they "reconnect"). You can see it here; http://forum.xda-developers.com/viewtopic.php?t=47977
Hope this is of some help for you!
RonnyGydar: I came across your little summary a little while ago and have done the registry fix, but the problem still exists! Do you think altering the value in some way would help?
richardlai,
I added the registry value manually...found a reg-file (or was it a CAB-file!?) that supposedly should add it...but when I checked later the key was still not added in the registry?
So I added it manually.
BUT, I do still have the problem...but that seems to be radio interference/distance so forth...since when I hold JasJar in my hand and don't move it around, I NEVER have an problem. ...and actually fairly rearly when I have it in my rugsack/backpack.
With 1 or 2 exceptions...where it lagged "all the time"...but then a soft-reset cured it.
So if you have this problem with your phone lying in front of you on the table...then it really sounds like it is the JasJar/Universal that IS the cause (and not interference)...and yes then the registry hack should help.
BUT I have not done any real testing of the effect of it...I am not sure how much effect it really has...all I know is that I had a "lot of problems" with lag before...and now I almost never have it.
...I hate those "diffuse" problems...when it is impossible to measure in a "scientific" way that "this cures it", and "this do not"! :-(
Sorry about the "little help" I give here...but this issue is a bit "fuzzy"...I have gotten it enough under control to that it isn't a problem any more (during a 1 hour workout, I will typically get this gap/lag 0-2 times...and that is not a problem for me...at least compared to what I experienced 6 months ago, where I was lucky if I could hear 10 seconds without any problems).
The stuttering problem seems to be permanent now... Luckily I have a HP hx4700 (which has a Broadcom bluetooth module) and works perfectly with my Jabra HT620s. Anyone using an A2DP ROM other than Qtek? I'd like to try a different ROM to see if it would make a difference.
only a second of sound
i use the qstarz bt stereo headset (http://www.qstarz.com/products/bh-q392s.aspx) and it works fine for phonecalls, but when i set it for wireless stereo and start a media player (TCPMP, WMP, Pocket Player...) i mostly only get sound for one second and then it shuts up. the players keep playing, the buttons on the headset can pause, resume and change tracks but there is no sound at all.
i get full wireless stereo playback occasionally, but i can't figure out what differs from time to time.
i applied the above patch with no success. anyone has a thought on the matter?
Ariel.

I use the BT620s with my Qtek 9000 without much trouble. Here's the trick:
Assuming you have paired with succes. Set headset and BT OFF before starting.
Turn bluetooth ON
wait a second or two
Turn headset ON
wait another two seconds
Now go to BT settings, and connect the headset.
Wait for the little pling sound (the activesync sound ).
Now start Windows Media Player and play an MP3.
Using this sequence has never failed me
edit:
I use the latest OFFICIAL Qtek 9000 WWE ROM. (Without the ExtROM though ) And i did not use any patches regarding A2DP or Bluetooth.
this is what i tried, many times. i get the activesync sound, sometimes from the speakers, sometimes in the headset, but almost always only one second of sound afterwards.
i found that by pairing the headset to the universal by pressing and holding the green button on the headset untill the universal recognises (doesn't take long) gives better results.
pairing it by the instructions of the headset (putting it in discover mode, and then searching for a device with the universal) will give me the one second sound almost every time.

Well, this has ALWAYS been the sequence I use (and I don't think you can do it in any other way). The real problem here is either the buffer memory or processor load.

Then there is no A2DP problem, the only solution is to lower the overal systemload. Stop all programs you have running, disable every today plugin that need frequent updating (memory, battery meters etc.) Free up as much RAM as you possibly can. I have AT LEAST 16 mb RAM free when playing music via BT.
Hello,
I did run into a problem with the bluetooth-stack on my TyTN with Schap's 3.54b german ROM. Everytime I use my bluetooth-headset (HAMA BT210)
it looks like the BT-stack uses almost all cpu-power. Switching programs or even open menues are VERY slow. Even UMTS-connections are slowed so much that MP3-streams start buffering. With Mortplayer and GSplayer. With the (now broken) usb-headset that came with the phone all works nice and smooth.
WHat can cause the prob? Maybe the headset using only SBC and not the
MP3-codec?
greetings!
P.S.: what does that bitpool and maxbitpool-setting stand for? around 50 the sound is okay to listen to and it only keeps stuttering every 30-60 secs.
Is there any chance to replace the usbheadset over the garantuee? Where is a cheap source for those headsets? Slowly I get angry that I can't use the headset working normally with the phone..

I don't think it's your headset. I would upgrade your rom to a newer one and try that. If that is going to be an issue, then try another BT A2DT. I think that is right, I may be dyslexic on A2DT. Anyhow that may fix it.
Bitrate is the stream quality. The higher the number the more processor is tasked. You should be able to lower from 50 to 40 or even less and not notice much quality drop this may help also. Try lowering and see what happens. I assume you are using stereo headsets too.
When I use the stereo headsets on my laptop, I too have the same issues you have. I believe it's the BT driver in my case. Good luck and let us know what fixes your issues.
Chris
Hey,
what do you mean to try a "new A2DT"? Different headset? The same prob appears. And yes, I wait for the new german Schap's ROM
And I still don't know what Bitpool and Maxbitpool really means I know that it has to do with the encoding- and transferingbitrate... but I can't find a info that describes both in detail...
Yesterdaty I updated to WM6.5 and now try to get everything working again. Somehow my TP2 won't pair with my bluetooth carkit anymore. With WM6.1 this was no problem. The phone still pairs perfectly with my computer (also bluetooth connection) so I think the bluetooth connection is ok.
When parining to my carkit it finds the device, then I have to enter a password on the TP2, and after that it just sais "pairing connection failed", and it will not work. I am sure the password is not changed since yesterday. I tried it several times. I do not know what to do anymore. Could this be a setting somewhere? I get the feeling my password is not send properly but have no idea.
Meanwhile I tried pairing my carkit with another phone and no problems there. So my conclusion is: something has changed with bluetooth, updating to WM6.5 which makes it now impossible to pair my TP2 with my carkit.
Is there maybe a programm for the TP2 which give me more controll over bluetooth (like maybe go to an older standard)?
I have exactly the same problem as you
good to hear I am not the only one. Hope someone will come up with a solution for this.
I did nor observed any issues when pairing my TP2 after reflashing to WM6.5
There is another issue however - I can not hear any voice until it is charging.
Unplugging of the charger fixes this issue immediately. Horrible...
Seems, HTC guys are saving money on testing by using us as Beta Customers.
Would a custom ROM be a solution for us?
I updated to the "energy 6.5.1 rom" and guess what..............
The same problem. The rom is very nice, but my TP2 still won't pair with my BT carkit which is very big problem for me.
Is there maybe a way to downgrade just the BT part of a rom to WM6.1. I read on different forums there is something that is called a BT stack. Could this be the problem?
I have a ton of problems with bluetooth pairing now. However, I don't know whether it's the fault of 6.5 or the Tilt 2. Here is what I am experiencing...
- On car deck or headphones, the skip buttons don't do anything
- on car deck or headphones, I have to disconnect Stereo Audio and then reconnect to actually get sound. It NEVER works when it auto connects.
- Music will do a brief skip when you shut the screen off
- Stupid message about volume control every time it connects (resolved by switching to custom rom)
- SMS or any kind of alert tone now turns music way down so that the tone is the only thing you hear. Which is super awesome when I'm driving my drunk friends around and they are singing along to a song when suddenly it mutes so everyone can hear my incoming text message.
Not a single one of these issues existed when I had my Fuze.
Same here
My bt headset (sony hbh ds970) and simply does not find the pairing...
I asume is a problem related to energy´s ROM

No I do not think so, because I used the official WM6.5 with the same problem. Does someone know a way around this issue. I strongly believe that if only I could pair I have some options to work with it (in 6.1 it worked like a charm). If I only could pair without having to send the passkey it would be great step forward. I presume with sending the passkey, the bluetooth of the TP2 sends out other "rubbish" that confuses my carkit.
My problem is solved and guess what, it had nothing to do with my TP2. The problem was my carkit. It has a maximum number of bluetooth devices (5) it can pair to and the last one (the WM6.1 version of my phone) had been reached. So a hard reset on the bluetooth carkit and the problem was solved.
Well, at least I now know how to flash a rom to my phone and I think I learned more about the phone reading through all the forums. Thanks all for thinking with me on this problem!
Does anyone else still have this problem?? I have removed all the devices from my car and continue to have the same pairing error just after entering the passcode. Stock Spint ROM worked great, but multiple 6.5 upgrades don"t pair..............suggestions/ideas??????
bluetooth settings, advanced, enable beam data exchange,check the box
Interesting.....I actually found a fix. Instead of pairing the phone with the car, I paired the car with the phone. I didn't even know that this was possible, but it did the trick!
