Permanent connection to a bluetooth headset - General Questions and Answers

Hi all,
I have HP iPAQ 514 with TomTom 7 installed on it, my goal is to hear all the TT's voice instructions through my bluetooth headset.
I've experimented with several settings as my headset is A2DP enabled, the result is that my phone is not fast enough to run TomTom and encode A2DP at the same time, so in the bluetooth settings of the phone I've unchecked Wireless Stereo and left only Hands Free checked for my headset.
Through standard hands-free profile it works, but with lags, i.e. I hear about 1-2 seconds sound from the phone speaker, then it's switched to my headset. Sometimes, if an instruction is too short, it switches even after playing it, so I don't hear anything. After a few seconds of inactivity, it switches back to "standby" mode.
I've found out I need to keep the connection between phone and headset "alive" to get rid of those lags - e.g. by playing music in the background, then there are no lags as the connection is active. But playing some sound (even playing "silence" just to force permanent connection) means extra load for the processor and the memory, and is very unpleasant. Is there any other way to keep my phone permanently connected with my bluetooth headset, not in just lag causing "on-demand" mode?
Thanks a lot.

stereo bluetooth problem

I've search for over two hours but it seems ive learned alot but i still cant find my problem the problem is that every time i connect to my car kit windows media starts working but then after i turn off my car and then turn it back on the music comes out of phone. So how can i make it play again on my stereo without reconnecting. i have elite rc3 rom and it has a2dp included.
I don't have the same exact problem you do, but I have a stereo bluetooth headset (Jabra BT8010 [awesome headset btw]) and if you don't wait for your bt to connect to your phone first before you fire up WMP OR connect while WMP is playing, it will freak out and do wierd stuff. For me it would either ignore my connection and play out the phone's speaker or play in my headset in mono mode in horrifyingly bad quality.
I hope that helps

Fuze - connect A2DP to car stereo for music, and HFP to Jawbone at same time?

Hi,
I searched the forum, wiki, etc., but didn't find an answer.
I have an AT&T Fuze with the stock ROM (WM 6.1). I know the Fuze is supposed to support multiple simultaneous bt connections. What I would like to do is connect A2DP to my Pioneer stereo for music playback, and also connect handsfree to my Jawbone 2 headset for phone calls while in the car.
I can successfully connect A2DP to my stereo for music by itself.
I can successfully connect HFP to my Jawbone 2 by itself.
I *have* managed to connect to both at the same time, by staying on an active phone call with my Jawbone, then telling my Fuze to connect to the car stereo. However, no music could be heard (from either Mortplayer or WMP). The phone call stayed up just fine though.
Anyone know if there's a way to get both working at the same time?
(And before you ask, I would just use the hands-free capability of my Pioneer stereo for phone calls too, but I've found my car is too noisy for anyone to hear me with the Pioneer's microphone unless I hold it right in front of my mouth, which defeats the "hands free" goal...)
Thanks for any help you can offer.
Best,
Chris
In your case I do not think that is possible since the concept of being able to juggle 2 devices at the same time requires 1 to relinquish control while the other goes active. It turns off the music so you do not get distracted while talking and reconects the music after the call is over.
It seems to be a software protocol if anything. Yes both can be connected at the same time, but both cannot be "active" as in doing both music playback and voice calls.
I have a bt headset that handles 2 profiles at once and according to the protocol, if a call comes in, it pauses my ipod and then picks up the call and then resets back to normal after the call.. Either you have to mess with the coding itself or someone has to come up with a workaround, but I do not think that is possible.
Thanks for the reply. I had hoped it might be possible for the Fuze to route stereo audio to one BT profile (A2DP), while non-stereo audio (e.g., phone call, system tones, etc.) to the HFP profile, almost as though the profiles acted as addressable "service ports" (ala HTTP, SMTP, etc.).
But, unlike with TCP/IP, I admit to knowing next to nothing about how the BT stack works and how profiles are applied to certain types of data (or, how data is routed to a given BT association based on profile).
Thanks again,
Chris
well the thing is.. the fuze can connect to multiple devices simultaneously, but based on the music and voice call order, it is prohibited from doing both at the same time. so therefore when there is no call, the music plays, but when a call comes it, the music is paused and resumed after the call is done. (obviously the call has higher priority here).
My only suggestion is to leave it as it is since it is done so that you do not get distracted while talking and probably while you're driving.
Multitasking is difficult when you're listening to 2 things, responding to 1, and driving at the same time. The more you multitask the less you are able to devote to your main activity (in your case, driving).
but yeah. if you can find someone who can mess with that and allow for both to be active at the same time, then congrats. Otherwise just think of it as a safety measure.
Except that, when I had both the headset and the stereo connected to the Fuze, the music *didn't* pause. It just didn't output (as though the volume was muted). In fact, in both Mortplayer and WMP, it appeared as though it was playing at ~2X the normal rate (just watching the track playback time counter).
I know what you're talking about re: listen to music, call comes in, music pauses, call ends, music resumes. That's the behavior I get when I use the car stereo for both handsfree and A2DP.
The behavior when connected to two different devices seemed to be different, though, so I hoped that might mean it was in fact possible.

yeah I know what you mean, but maybe the fact that it tried to do both tripped it up and so it took the call as a higher priority and focused the data towards the call.
atleast that is what I think.
I have almost the exact same configuration, except I am using a Sony car stereo but have a jawbone. What I have to do every time I get in the car is the following.
1. Let my stereo connect to both hands free and wireless headphone services.
2. Open bluetooth settings
3. Manually connect to my Jawbone.
It works great.
ATT Fuze
Energy Rom 072209
Old jawbone
Sony XPLOD Car Stereo
I'll also add it's pretty neat to be able to push the jawbone to activate MS Voice Commander and choose what music I want to play over my car stereo.

Thanks for the reply. I'll give that a shot. I'm not sure that my Pioneer stereo will automatically connect both handsfree and A2DP. I know it will do handsfree automatically. We'll see...

Problem with Bluetooh and Headphones

Hi, I own Asus P535.
After upgrading from WM6.0 to WM6.1 I have not been able to use my BT stereo headsets.
If I'll connect headphones like "High definition audio" and then i wannt play music from audio manager or WMP will start but then it will become choppy as if the connection is going on and off every second (like "sporadically data transfer").
Didn't have this issue with WM 6.0. I also noticed the elapsed time of the song in progress is also erratic.
When the BT stereo headsets are connected like "Handsfree" then they become disconnected in 2-10 second.
and next what i noticed:
Bt manager have something what control range of BT... (signal strength) this function doesn't work.. still show just proper even if i walk away..
and sometimes its possible to find the point when the music is playing normaly.. but every move with mobile or headphones interrupted playing.
(BT-PPC/PE 1.7.1 build 9807)
PS: with any other deviece this BT stereo headphones work correctly.

Bluetooth audio skipping issues when also paired with phone

So I use bluetooth for both phone and music in my car but my phone pairs to two separate devices. For the phone it pairs to my Audi MMI system and does so correctly every time. For the audio I have it pair with my Blackberry Stereo gateway which is hard wired into my aux input.
The issue I'm having is that if I'm connected in both Headset (Audi) and a2dp (Blackberry gateway) modes, the music will start to skip after a minute or two. It works completely fine for a few minutes, then I believe the phone is going into some sort of sleep state as it'll begin skipping fairly often. If I turn the screen back on, the skipping goes away. The strange part is that if I disconnect the pairing with the phone, the skipping never happens. It's almost as if there is enough juice in awake mode to correctly power both bluetooth connections, but if it's in some form of low power sleep mode, it's not able to handle both connections so the bluetooth audio skips.
I've also found that if I'm paired to both, the call quality over bluetooth is slightly lower with a bit of crackling/garbling, but not nearly as bad as what I get with the audio. I can deal with the phone side of the issue, but I can't listen to music that skips every 5 seconds.
Anyone else have this issue? I wish I could set it so the phone wouldn't sleep when paired to both devices! I don't mind a bit more battery drain while in the car if my phone is actually usable for what I want to do with it.

Random Bluetooth Connects/Disconnects?

Does anyone have Bluetooth issues on their OnePlus 7 pro? It keeps randomly thinking its connected when its not and will start music that was paused or start my Trigger tasks that turn off wifi, turn up the brightness, and max out media volume for when I'm connected to my car. Sometimes while in the car it will randomly think it disconnected and do the opposite functions it is very annoying. Is there some sort of Bluetooth fix for this?
I should probably mention that it does this when none of my paired devices are even on or in range
Yes, On Tmobile and it happens when I am on a phone call. It will switch from BT to the phone speaker without a warning. It is affecting my job as well now. No solutions I have seen.
