Multiple bluetooth connections?

I wonder if anybody knows if it is possible to have two (or more) divices connected at onceon a Blue Angel?
eg. Tom Tom 6 plus a hands free connection.
I have tried every configuration I can think of, different ports ect, but to now avail.
With the gps connection up and running, as soon as you turn on the hands free , the gps connection link is lost, turn off hands free and it will resume connection.
I am using BA WM5 AKU3.5 R4 - xplode's excellent rom
In GPS settings
Program is using COM 5
Hardware is using COM 0
Manage GPS settings set to Auto
In Device settings,
BTGPS unit is on COM 0 (Serial box ticked)
Hands free is unassigned
Any help will be much appreciated.

any idea's anyone?

On Last Baniaczek's ROM I made an experiment just a moment ago: BlueAngel, Navigation system (Polish one, Automapa), plus GPS on Bluetooth and A2DP headset - first connected headphones, then added GPS (using automatic GPS connection - it's M$ Stack) - Everything seems to be working fine. I thought it was a bit unstable at first, but AD2P stops sending data, when there is no sound from the device.
GPS Settings are default: COM6 for applications and GPS has COM7 assigned on Hardware tab and in Bluetooth outgoing port. Quite seamless.
then I made the 2nd one: same headset connected in Handsfree mode: indeed turning on navigation made it connect and disconnect every few seconds.
For me it seems to be fault of M$ BT stack: it cannot hold 2 similar streams on BT (COM and Handsfree/Headset are both typical serial connections of highest priority in BT stream). At the same time it can cope easily with two different streams (A2DP is lower priority, high-bandwidth BT connection).
I'm not sure, but I think when I used old Helmi 1.3.2 with Widcomm stack it could cope with GPS and Handsfree at the same time, but it needs more testing.

jakubd is right it is limitation in MS BT Stack

Don't give up and it should start to work. I have similar problem with BT GPS and BT headset. GPS goes on and off while headset is on. And than I try to switch headset off and on, BT off and on, GPS off and on and after some time it start to work together with no problem. It takes first 10-15 minutes of my voyage but then it works for the remaining few hours.
Sorry, but I still didn't find out what combination make it work. If I do, I will post it here as workaround.
And I'm almost sure that I had no such problem with Helmi 1.4 ROM.

Thanks guys,
have tried every configuration I can think of, but its always the GPS connection that is dropped, not the hands free, this would not be a problem if it was just when you are answering a call.The GPS reconnects only when you disconnect the hands free connection. ?
Has anyone Successfully used the Widcomm stack with this type of setup?
I am sure alot of members would find this usefull if it can be made to work!

This is my experience:
ROM : Helmi_BA_WM2k5_AKU3.5_v1.4.CF2.R2 (baniaczek)
Tom Tom 6
GPS : Bluetooth
Headset : Nokia BH-300
When the headset is on and connected, the GPS doesn't work (TT say no GPS found). When I turn off the headset, the GPS is working.
With ActiveSync I have the same problem: when the headset is turned on, I can't establish a connection with the PC via bluetooth.
BUT!
If I use a different headset, a Logitech HS03, all is working fine. I can leave the headset on and the GPS is working. I can receive incoming calls with no problem (using the headset) while I'm driving without loosing GPS signal.
With ActiveSync is the same: I can connect my PC with the headset on.
I have no idea why there is this difference with these two headsets, but one is working and the other no. I don't know if the problem is the MS BT stack, but my test demonstrates that under some circumstances this stack could manage more than one connection at time.

Bigmike, my point exactly. As I wrote in my post I keep turning on and off until finally it works. So there are some circumstances under coexistence is possible.
It seems that devices try to use same port which means that first device does not reserve port for itself. I am not an expert but it seems if we could somehow force devices to use different ports problem would be gone.

If this works with one set and doesn't work with another, it might be connected to list of profiles supported by the headset:
1. Headset - HSP - more common, typical profile for use with cell phones (supports AT commands)
2. Handsfree - HFP - audio-centric, used mostly in cars, less common
http://en.wikipedia.org/wiki/Bluetooth_profile
My SonyEricsson HBH-600 has both profiles (checked with services list on SonyEricsson phone), but I don't know how to select which profile is used by headset.
Just a thought...

I hope you haven't misunderstand my previous post. I haven't in mind to minimize the value of your post (very useful is someone will try to investigate about this problem).
I was thinking that somebody, reading your contribute, could wrongly think: “you're are a lucky guy and turning on-off the headset repeatedly you crash some library and the two devices are working together”.
My intention was to remark the fact that under some circumstances the headset and the gps can connect together every time and always at first try: it's not lucky, crash or random events.

I have a similar thought.
It seems to me that some times ago I have read that it should be possible to change some profile's parameters “playing” with the registry.... but I could be wrong...

No I have not, bigmike, just the opposite. I was delighted that somebody confirmed my point.

Couldn't agree more. And I think it's worth trying to resolve it.

Multiple BT connections - solution?
I think I find a solution for this, or maybe we can call it workaround. At least it works for me.
As I wrote in my previous posts, I could make it work every time just didn't know how. Now I established repetable procedure which worked every time for reasonable number of experiments.
Secret was to turn on BT headset (in my case Plantronics) and BT GPS device (Haicom 406-BT) and GPS program (iGo) first, and then go to Comm Manager and turn bluetooth on.
So my procedure is:
1. make sure that BT is off in Comm Manager
2. turn on BT headset
3. turn on GPS device
4. open iGo program
5. minimize iGo
6. turn on BT in Comm manager
7. open iGo and make sure it's connected
8. go to phone and call myself just to make sure it works
9. back to iGO and make sure it works
If 8 or 9 fails for the first time, just turn BT off and on again in Comm manager and check it again. I never need to do this more than twice.
Try this, guys, and good luck.
P.S. I don't know if it matters, but make sure that in Settings/Connections/GPS "GPS program port" and "GPS hardware port" is set to (None) and "Manage GPS automatically" unticked.

Very good! Many thanks Sassa!
I have tried for two times your procedure and both tries worked very well (with TomTom6 and Nokia BH-300)
I use a slightly different procedure:
1. BT off in Comm Manager
2. turn on BT headset
3. turn on GPS device
4. turn on BT in Comm manager
5. open TomTom 6 (wait some seconds and make sure it's connected)
6. go to phone and call myself (on the first call the headset is disconnected)
7. back to TomTom and make sure it works
I have noticed a different behavior of the BT headset having the BT always on (in Comm Manager) and using this procedure... but I need to make some tests before writing more.

Bluetooth Stack problem on Kaiser - automatically re-establishing pair

Hi all,
I have posted this question also over a 4winmobile as I cant access xda-dev from work. Hopefully someone here can help.
I've been having difficulty with my Kaiser and a Parrot MK6000 car kit. I have tested the carkit with a Nokia as well, and have some results to report to aid in troubleshooting.
The Nokia was paired with the Parrot MK6000 kit, answers and makes calls and streams audio no problem. When the car is turned off, the pairing ends, when the car is started again the pairing starts back up ... auto, no probs. In addition, if you make a call with the phone, at the end of the call the pairing is ended, but within a few seconds is re-established.
On my Kaiser, I can pair the phone and car kit, but if the connection is lost (ie the car is turned off or bluetooth is stopped on the phone) and then I turn the car back on, it will not automatically pair. It attempts to, the car kit mutes the car radio and plays a tone, but the pairing is not established by the phone. It continues to do this every 30 seconds or so, but does not establish a connection.
Also, if I make a call with the phone when it has been sucessfully paired, on ending the call, the phone will not re-establish the pairing.
My conclusion is that all of my troubles relate to the fact that the pairing will not re-establish once lost.
Is anyone able to assist? I have upgraded the Kaiser radio to 1.27.12.32 (yes ... just tonite, see http://forum.xda-developers.com/showthread.php?t=349528&page=2) but have also tried radio roms 1.27.12.11 and 1.27.12.17 with no success. The ROM version is 1.81.861.0. Ive also tried installing some of the BT stacks that were developed up for the Hermes with no success. I've also installed Jetware with no sucess.
Getting very frustrated!

Have you tried these registry tweaks? http://msdn2.microsoft.com/en-us/library/aa915920.aspx

There is a know problem with the Parrot kit and you will find a thread in this forum where a member has contacted Parrrot who replied that they are addressing the issue.

Hi, thanks for that pointer ... most of what is described in that MSDN library isn't in my registry.
Im going to manually insert them all and see what happens.

Still no luck
I tried updating the Reg with the tweeks as suggest ... but still no luck. All i get is still the initial pair, but on disconnection, no automatic re-pairing of the device to the car kit.
Im doomed at this stage.

You're not alone. I have the same problem with my Motorola S9 headphones and Microsoft SYNC in my 2008 Ford Edge. Sometimes I have to turn BT on and off a couple of times for it to connect.

agreed
Turning the BT on and off a few times has also be part of my "solution" package.
This really isn't acceptable though. This device should automatically pair up, just like every other BT device does. BT is a protocol that should be adhered to and just work.
I have also tried this on my other WM device. It pairs a little better, but is not great. I've tried compairing the registry values of that device to my Kaiser, but I just dont understand the functionality of the reg settings enough to work out what to change.
Is there some developer out there who can help? This type of problem was experienced by us all back in the early days of the Hermes and this community sorted it out.
Can any developer out there help, like working out a port of the Widcomm BT stack for Kaiser?
a

Interesting. I have a Nokia CK-7W bluetooth car kit and the Tyn II has re-connected/connected to the kit every time. Actually more reliable than my SE K800i. Sorry that it doesn't help you.

Hey Juzzman,
nah, that doesnt help ... but does increase the frustration level!
Seems like you need to have a Nokia component in there somewhere for it to work ;-)
Anyhow, Im still convinced it is a bluetooth stack problem in the Kaiser. I'm going to try flashing one of the AT&T based roms and the other radio version and see what happens.
Cheers

I've had BT issues with all of my HTC devices, it's very frustrating.
Currently I've got a Kaiser (Orange), E650 (Orange) and a new S730, none of which work on my Pioneer headunit without Jetware.
The Kaiser with Jetware pairs up ok, but the sound is really tinny.
The E650 with Jetware sounds fine, but I can only send 150 contacts to the headunit.
The S730 doesn't pair, haven't put Jetware on it yet.
In the past I've had BT issues with M3100, C600, C500 etc etc.
Why the hell doesn't MS sort out their bloody BT stack!!!

Bluetooth problems
I am having the same problem with my JVC bluetooth unit BT1000. It will pair ok first time, allows me to make 2 calls. Will not the reestablish a connection/pairing. JVC worked fine with my sony erricson and nokia phones. Anyone found a cure to this?

Same problem with the stock AT&T rom (1.27.12.11) with the H700 headset.
Turn bluetooth on it normally sees the headset. If not turn it off and on again to get it to work. Once working it normal looses the connection after an hour or so.

Could it be a BT 2.0 Compliant issue?
I have posted this same problem earlier in xda-deveopers, on htc wiki and aximsite. Many people have viewed and are experiencing this same problem, but no one has posted any solution specific to my problem either. I hope a developer can solve this one for us. Is it a BT stack problem, or a BT 2.0 compliant problem, or a need for an updated ATT ROM to solve this issue? (I currently am using the stock ATT ROM 1.57.. that shipped with my Tilt.)
When I use my Motorola H700 with the Tilt the BT works fine, UNTIL, I use the voice speed dialing from the Tilt. Once I use the voice speed dialing directly on the Tilt, the Motorola H700 will no longer connect. I have to do a soft reset or go through the pairing process again. Once I re-establish pairing again, the H700 will continue to work fine, UNTIL, I use the voice speed dialing on the Tilt. Then we're back to having to do a soft reset to again establish H700 connection with the Tilt.
NOW, I just received a call back from an HTC tech who told me the problem is likely due to the Motorola H700 being only BT 1.2 compliant. He recommended that I try the Motorola H12, which is BT 2.0 compliant, but he could not absolutely guarantee this would solve my problem.
Does anyone know for SURE that the Motorola H12, being BT 2.0 compliant, will solve my problem? Or is there another solution?
Note: I have tried MS Voice Command 1.6 (full version), but the above problem still occurs. I have also tried Jetware, but again, no go. I am not sure that there is going to be an updated AT&T ROM to solve this issue either.
Additional Note: I have also tried other BT devices, such as the Jawbone, and the Plantronics Voyager. All do exactly the same thing as above.
Anyone have any solution? If the Motorola H12 is the solution, that would be great...
Thanks in advance.

I'm having the same problem with my new carkit. Did anyone ever find a solution to this??

Kaiser and A2DP carkit

Hi all,
I'm having some troubles with my carkit in combination with my Kaiser. I'll try to explain;
I connect my Kaiser to a JVC KDBT1 headunit. This unit supports a2dp streaming (thus the wireless stereo profile), and phone calling (the handsfree profile). It works flawlessly, stereo streaming and calling apart from each other that is. If I'm listening to music on the bluetooth audio source, the wireless stereo profile, and I get a call, the headunit switches to the bluetooth phone source, and I get perfect handsfree calling. But the troubles start when hanging up the phone. The headunit then switches back to the bluetooth audio source, but by then the Kaiser has disconnected the wireless stereo profile. After reconnecting, everything works again. But reconnecting while driving a car is something I don't wanna do to often
So my question is, why does the Kaiser disconnect this profile? It looks like a timeout or something, so I tried changing registry settings by using this link as a guide:
http://msdn2.microsoft.com/en-us/library/aa916863.aspx
Unfortunately this didn't solve my problems.
Someone who can tell me what's wrong?

The same problem in my car. any solution?

try this
try disconnecting from the call using your remote control from the steroe, instead of pressing end on your phone or waiting for the call to end. also install on your phone the btfix.cab. i had the same problem and i tried both of those solutions. as well as set the sync b/t your car and phone to happen automatic.

You might be best off by giving everyone a little bit more information -
What ROM are you running?
What radio?
What version of everything - AT&T - Orange - TMobile?
I have a Stereo headset BT and it switches back and forth easily from phone call to steroe and back easily - no problems - This is the same as your scenario EXCEPT that it is a headset and not a CAR but same technology. So I suspect that it is your configuration that is hosing you up.

Just a word of caution on this application...it really burns through your battery if you have it on your Today screen.

Just tried the same version as whk (the official ATT rom downloaded from HTC USA) but the same problem still exist. Once a phone call is longer than 30sec. The A2DP will drop after the phone call.

I have a Parrott wireless in my Lincoln. When I get in it recognizes the Tilt with no issues. I travel from Dallas to Houston and talk on the phone all the time. I can answer using the Parrott or the phone - it does not matter.
I never have an issue with phone calls.
When I use my Motorola headset I have no issues switching back and forth between phone calls and music. It works flawlessly.
There are a couple of issues that I do have -
1. when you use either the HT820 or HS820 you are SUPPOSED tob e able to press the button on the headset ONCE and it is SUPPOSED to re-dial the last number - both of mine simply beep once and do not dial anything.
2. I have Microsoft Voice Command - (love it by the way) and I have it set to read incoming message headers only when BlueTooth is enabled. This means that while in the car it reads me the incoming detritus so that I know if I need to read my emails right away or not. PERIODICALLY - it will read me the messages on the Tilt speaker (this means that it recognized that there was Bluetooth available but did not make the jump to light speed for what ever reason. USUALLY it rectifies itself after a couple of messages.
Sorry that I was not of more help.

I thought that a2dp toggle program was just a software switch of sorts..wonder why it drains the battery?
I was going to load that program in hopes of using my Motorola H700 BT to listen to music and Slingbox..mono of course.

Hi Bill,
Thanks for your info anyway. Today, I just tried my good old Eten M600 on the same carkit but I couldn't reproduce the problem. It automatically switch back to a2dp after an > 30sec phone call. So, I think it's Kaiser's problem.
For BT redial, some headset (e.g. my sony Ds220) 1 press for voice command, and 2 press for redial.

I wrote a mortscript to automatically reconnect A2DP after a phone call ends. It has solved my problem. You can find a copy of it at http://forum.xda-developers.com/showpost.php?p=2267998&postcount=516

Disable today screen, and use cmdline switches. It's the today screen which drains battery!

JVC carkit problems
Hi
I was reading your postings, and noticed that some of you are also the jvc BT-1 car radio.
Does anyone have the same problems as me ?
When I make a phone call using my carkit and afterwards hang up the call, my connection with the radio is somehow troubled.
When I directly make another call, my audio isn't routed through my radio.
When I wait making a new call, after several seconds my radio gets disconnected and a few seconds later it will connect again. At that point I can make a normal call again.
The worst problem however is, when I leave my car. When the radio turns of, my Kaiser doesn't return sound to the normal speaker. I have te reset the phone.
I am using hyperdragon III Rom 25-09-08 with radio 1.65.24.36.
Any idee ?
Thanks Maikel

Diamond Bluetooth HeadSet Bug

Ok, not sure if anyone got the same problem as mine, but here is my problem:
I have a Diamond using AZTOR v7 Rom, radio vBS14 if that matters and Sony Ericsson DS205 as my headset. I start my bluetooth on my diamond and can pair up with the DS205 without any problem. I can also listen to music without lag and sound is also crystal and solid.
When there is a call kicks in, I can answer the call by pressing a button on my DS205..... However, the problem comes when I end my call, the headset will be disconnected afterward and I have to manually press a button on the DS205 to make it reconnect. Each time when I make a call or when I receive a call the headset will be disconnected.
Luckily (or not), I found a workaround: Whenever I pair up my headset, I need to go to Setting -> Bluetooth -> and "Refresh" the services that I want to enable on the DS205 headset. That involves un-checking the services enabled (including "Wireless Stereo" and "Hands Free") and re-checking the services again. After I have done this "resetting", the disconnection problem I described above will be gone.....
Each time I restart the phone or have the bluetooh disabled on the phone, I need to go through that manual procedure again to make my headset work perfectly.
As you can imagine, that is quite annoying.......does anyone have the same problem as me?

I don't have this problem, but i have another problem, when i use the orignal rom, i can use my headset(jabra bt3030) in my diamond and it will automatically connect to use hands free and wireless stereo mode when i turn on bluetooth, so when i change to use swift 7.5 full rom, i have to resetting the bluetooth in diamond everytime when i close bluetooth

I can only get wireless stereo for my Plantronics Bluetooth Stereo headset. Any ideas why I can't get hands-free. Radio issue?
It was possible with some earlier ROM, but I can't remember which... (yes, I'm a flashing addict).

I'm having the same exact problem & it's annoying as hell. At this point, I can't get the bluetooth function on the phone to activate at all. I use the same bluetooth on another phone with no problems whatsoever, so I know it's the phone. I'm running the original rom.....not a flasher.

Have you tried Jetware?

Sorry, just installing this doesn't change anything. Still no hands-free.
Is there a specific option you want us to set?

Luckily (or not), I found a workaround: Whenever I pair up my headset, I need to go to Setting -> Bluetooth -> and "Refresh" the services that I want to enable on the DS205 headset. That involves un-checking the services enabled (including "Wireless Stereo" and "Hands Free") and re-checking the services again.

Yes - I have a very similar problem with my jabra SP700. The Diamond 'forgets' the wireless bluetooth mode every time I disconnect the two devices (although the Stereo Bluetooth icon is still showing in the status bar).
For a short while I was having to re-pair the devices every time I got in the car - until I found the same workaround as you.
There must be a proper solution???

Hello, I had that problem in my HTC Diamond with Pioneer DEH-700bt and my jabra 3030 and she solves when changing in the registry the key to it that identifies the device in pocketpc HKLM/Software/Microsoft/Bluetooth/Sys the key "COD" and I introduced the value decimal 5898764 that identifies the device in smartphone
luck

I have this value in COD key but I have the problem anyway.
Any solution to this annoying problem?

i use my diamond with my bluetooth handsfree kit in the car, it is classed on the phone as a headset though. the sound is ok, a bit echoey but ok. but the microphone doesnt seem to pick up my voice, i have to really shout for people to hear me, on my old Xda Orbit it worked fine. any ideas?

Autoconnect A2DP when in range?

Hey Guys!
Is there a way to tell WM6 to automatically route Audio through A2DP as soon as a paired device supporting the profile is connected?
Clarification:
When using a Hands-Free-Headsetfor telephony you can pair it once, then turn it off, after that it is automatically connected to the phone as soon as you turn it on again.
In contrast to that a Bluetooth Stereo headset is not automatically connected, you have to manually activate it in Bluetooth Settings first before you can listen to music through it.
Especially with my car stereo used as "A2DP Headset" (which loses power every time the ignition is turned off) this can get highly annoying.
Is there a way to tell Windows to automatically "use" A2DP-Peripherals when available?

Try A2DP Toggle: http://www.teksoftco.com/index.php?section=freeware
The Today-plugin migt reconnect automatically, but it has a memory-leak...
To easily manually reconnect, you can create a shortcut to the exe:
\Program Files\Teksoft\A2DPToggle\A2DP.exe
Then you can put that program on your today screen easily.
And if you want a nice icon with that shortcut, you can change the shortcut file to:
53#"\Program Files\Teksoft\A2DPToggle\A2DP.exe" "-a2dp:1"?\Program Files\Teksoft\A2DPToggle\settings.exe,-0

Yep. The WM bluetooth stack sucks. It works better with some stereos though. I tried it out in the store with I believe a Pioneer (with bluetooth 2.0) and it was perfect. Turned it on and a2dp connects. Switch to another input and a2dp disconnects. Switch back to bluetooth audio and it connects. It was flawless. I ended up ordering the kenwood built in bluetooth unit (bluetooth v1.2) and it is terrible. I must manually toggle the bluetooth connection (I use a program that I wrote to do so, kinda similar to the above the above poster posted). Also, sometimes after a call comes in it wont reconnect. Sometimes i must power off then on the headunit a few times. Wasnt this thing supposed to make things easier?! A real shame because I love everyting else about the kenwood head unit. It works better with some ROMs on my phone (this is with a tilt; xperia on the way ).

Yeah, A2DP Toggle works for me as well, It's just dumb that this phone cant just do that itself. My old W880i could! I'm using a Sony DR-BT21G headset

A story to learn before you you buy the head-unit I spent almost an hour at Fry's to try many units w/ my Tilt as well (Sony, Pioneer, Kenwood, JVC ...etc) and ordered online w/ the JVC unit. Excellent sound (compare to other model) but disconnect after phone call issue exist. I believe it's HTC fault since my Eten M600 (MS BT stack) and Asus P525 (Widcomm) doesn't have this issue (but others....). But I got to admitted HTC one do have the best sound quality.
BTW, my JVC BT-1 will auto connect my X1/Tilt when I start my car and I think it serve my purpose.

I have created an application wich runs the commandline setting automaticly, so you never have to do anything again it connects automaticly. You can find it here: http://forum.xda-developers.com/showthread.php?t=502549
