bluetooth LAG - Touch Pro2, Tilt 2 Windows Mobile General

I found some registry changes to resolve a lot of the bluetooth issues as far as the connection disconnecting after 1 ring, the hangup issue, etc.. HOWEVER.. now I have an issue with LAG where when connected to bluetooth, after a while the phone will lag and you can see everything moving in slow motion.. if I disconnect the bluetooth then the phone speeds back up.. ANY IDEAS? the only device I see this NOT happening with is my STEREO BLUETOOTH HEADPHONES MOTOROLA S9... Here is what I changed:
1. Modify the HandsFree plug-in:
HKLM\Software\WIDCOMM\Plugin\HandsFree
i. Change SupportedFeatures to 45 (default is 1135)
ii. Add value HFBDA binary, set to same value as LastConnectedBda
iii. Add value HFDeviceType decimal 2
2. Modify the WIDCOMM bluetooth general settings:
HKLM\Software\WIDCOMM\BtConfig\General
i. Change bdaddr to (no value)
ii. Change DisableReopenAudio to 0 (default is 1)
If anyone can figure out how to resolve the bluetooth LAG I would appreciate it....

anyone have a fix? also now the last received, last called and missed do not grab info from the phone.. it only shows the calls I have made using the bluetooth device...

I have noticed a similar lag, and, on my end it's not so much after a phone call, but after anything associated with BT (I use a Moto HX-1).
Does not do it all the time....If I am in the middle of doing something with the phone, and I get a notification through the ear piece (voice command), everything starts to stutter. Side note, at times, the silly phone heats up, and battery starts to drop.
I reran an OLDER rom for a couple days, and didn't have ONE issue.
Sounds like something in the later rom builds has changed something in the BT?

I've also noticed this recently. Whenever the phone is hooked up to my in-car bluetooth (Audi), it runs like an absolute dog. As soon as it disconnects, it runs fine again. This is most frustrating as it can make the phone unusable when connected to the car kit.
Anyone gotten to the bottom of this yet - is it an issue with a newer bluetooth stack or something?

SX66 Issues

I have had my SX66 since Wednesday. Here are the issues I have found, and if anyone has any suggestions, PLEASE let me know!
1. Bluetooth is really bad. Scratchy, drop connections, says signal is low even when headset (Jabra 250) is right next to the unit. (I have the O2 3500 stack installed)
2. Bluetooth response time for headset answer button is SLOW, as is sending the data to the headset when a call comes in and is answered by headset.
3. When Bluetooth is ON, the phone will turn the display ON at random intervals, killing the battery if the backlight is left in the on mode.
4. WiFi is horrible, drops connections constantly, even in same room with router (Linksys w/5db antennas atached). Also, it will NOT work with a network unless the SSID s broadcast - so much for security!
5. The phone features are SO vastly different than regular phones, it makes you wonder if it is working. My unit will NOT echo the DTMF into the headset (which every phone I have ever owned did) to confirm pressing (for VM retirval, etc.). Very confusing.
6. Answer after x rings is a joke. I have it set to 2 rings, and it will never answer automatically headset or not...what's the point?
I hope someone out there can help, otherwise, I may have to put this baby on eBay...because it really sucks at this point!

Update
Well, I downloaded the O2 update, and that seems to have made a difference in the STABILITY of the BT connection; the unit did not drop my headset at all during the day; further the "response" of the SX66 to a command from the headset seems faster.
Also, since I installed this update, I have NOT seen the screen turn on...perhaps this helped that problem...?
:evil: The BT is STILL scratchy/noisy, but not as bad...perhaps the next round will help...?
I will keep you posted!
I have/had the same issues you are describing. The bluetooth patch 3500-124 fixed almost all my BT issues except the extremely low signal. I tried the HS810, HS820 and the Jabra 250. All were horrible. I even went as far as installing the latest i-mate pda2k ROM 1.22.00 wwe on my sx66. I finally took the advice of a poster on another forum (thanks mswlogo) and purchased a sony hbh-300. So far it has been great. It handles the low signal like a champ and doesnt offer any static or popping.
Need a friggin repeater!
Someone should make a BT repeater...or maybe I should try one of those internal antennas..."as seen on tv!"

stereo bt but mono sound

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;
-----------------------------------------------------------------------------------
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...and so did richardlai).
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. 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.

Bluetooth visibility automatically switched off

Hi. I've playing for several days with my new trinity and have installed AX3L 2.0.7.0. So far i'm pretty happy with it, apart from a couple of problems:
I cannot get wireless stereo to work. I can connect the pda to my car's stereo, it identifies the HTC as a bluetooth audio device but after a few seconds, it disconnects. If I start playing something while in Wireless Stereo connection, it plays it through the pda's internal speaker.
I can't figure out how to leave Bluetooth's "Make this device visible to other devices" on. I have switched it on a dozen times and a dozen times it has been disabled. I'm not sure if it is disabled whenever I turn bluetooth off or after a certain amount of time. The fact is that it becomes disabled.
I think my last problem has already been covered here, MMS. I've seen a couple of notifications about a MMS being downloaded but there's no MMS in the inbox, i guess there's something blocking it, but that's what worries me least.
Great job, AX3L!

First, try to install my new rom (2.0.8)....i have cleaned the registry and added some tweaks....maybe bluetooth become working (for you!)...
If not, try to edit the setting using "TweakUI"'s AD2P tab (Settings -> System)
I'll give it a shot this weekend, when i can backup my data so nothing gets lost. (BTW, where is the backup device I used to have with activesync with my old ipaq3970?)
I have searched around to find documentation to understand TweakUI AD2P settings, but i didn't see it around. Any clue whether Joint Stereo Should be enabled, meaning of Bitpool, Audio Gateway numbers?
Try to:
REMOVE the following values from the registry at HKLM\Software\Microsoft\Bluetooth\A2DP\Settings if they are present:
- BitPool
- MaxSupportedBitPool
ADD the following value to the registry at HKLM\Software\Microsoft\Bluetooth\A2DP\Settings:
Name: SampleRate
Value (DWORD): 48000 (decimal)
SoftReset the device and try again
ONLY IN CASE not working....
install the Sleuth255's Patch http://forum.xda-developers.com/attachment.php?attachmentid=31755&d=1165092579
(after install, softreset your device)
Thanks, that did the trick of bluetooth visibility not auto-turning off. Anyhow, it seems there is some kind of incompatibility between Pioneer DEH-P75BT (my car receiver) and the HTC. As a hands free, I have to manually set it from the pda as Hands free so they pair each other, and BT Audio function connects as before, but sound is still played through pda's speaker.
Thanks for the tip, AX3L

Froyo Bluetooth issues - Mostly Solved

Hopefully someone else might find this useful.
I updated to retail froyo (first Telstra AU 3.4.2_145 then Nor 3.4.2_177). both times full sbf flash and wiping data/cache/dalvaik to try and solve my issues so it seems common amongst all Retail 2.2 builds.
Issue 1.
Bluetooth Headset would pair fine and make calls and stay paired. But once headset was turned off and turned on again it would disconnect AFTER hanging up on a phone call. Pressing headset button would then pair it again.
RESOLUTION: edit /etc/bluetooth/audio.conf file from
---------------
# Do not require master role for incoming connections
Master=false
------------------
to
----------------
# Do not require master role for incoming connections
Master=true
----------------
Seems the first time it was paired the handset was the master, but subsequent times the headset became the master, thus dropping the connection once the phone call was finished.
Issue 2.
CPU usage at 100% when handset paired with Car Stereo (JVC KD-BT1). Pretty much no other app would work as the cpu was pinging. I used Catlog to take a dump while this was happening and noticed text messages from over a year ago being transmitted. Turns out 2.2 update enabled Text messaging transfer to my phone and since I had 1600+ texts this was capping the CPU.
PARTIAL RESOLUTION: delete the text messages. I havent worked out if the issues is with the Car stereo not liking that many texts, or if the text db is being refreshed every time the phone pairs. IF anyone has any ideas or even how to stop the text message syncing (i did try stopping the process bluetoothMAP but that didnt help).

Bluetooth audio routing

This has been driving me crazy since last Wednesday. My Bluetooth devices (car and headsets) routing changes by itself. The Bluetooth doesn't disconnect, but the audio routing goes back to the phones speaker. It seems to be related to wifi as the issue happens when I move out of range bit this is not the only time it happens. When I leave home, the car routing will change at almost the same distance but once changed back will not change again. My headset OTH will change routing again and again while I'm working around my yard. This never occurred before a week ago Wednesday. I have turned off the 'home' feature in settings, dissociated and reassociated the devices and reboot the phone. I'm stumped. Any insight will be greatly appreciated.
