How many Bluetooth devices concurrently?

Hi,
I have an O2 Blue Angel, and I'm keen to use it with:
- a BT headset for phone calls
- a BT GPS mouse for satnav
- a BT link to another mobile for GPRS intenet access (not available on the sim I need to use in the XDA)
Is it possible and realistic to have all three BT links working at the same time?
Cheers
Peter

Hi Peter,
I have used multiple bluetooth connections with no problems (after initial problems on 1st release of XDA II). You could however have a problem with trying to connect to gprs and using your headset to make a call, BT GPS & Jabra BT200 work fine simultaneously (when XDA II & TomTom are in the mood to play together!) but mine always disconnects gprs when I receive or make a call.

Thanks, Chop. That's good news.
I may not have a problem with the GPRS disconnecting as I'll mainly be using it for small and infrequent GPS tracking and traffic updates. It might be a pain to have to reconnect though, if my GPS solution (currently CoPilot) doesn't automatically do so...
Cheers

I can not dial up using a bluetooth phone. Does any one esle have that same problem?

Different Bluetooth Stack?

I've been struggling for several months now to get my MDAC III working with my built-in car Bluetooth hands-free. The full details are below, but in short, I'm told that the system seems to work OK with Wizard, and I'm wondering what about the Wizard could be different to the Artemis (Bluetooth stack perhaps?), and if there is a difference, is there anything I can do about it?
The full issue: The system I'm trying to connect with is in a Land Rover Freelander 2 (LR2 in the US) Initial pairing was a bit hit and miss, but now I've got the the phone paired with the PTI, that's not a problem and they automatically pair whenever I start the car.
I can succesfully initiate or answer a call from the car, but the call itself isn't routed through the car's speakers/mic, it just goes through the phone as normal. However, once in a call if I select the "privacy" option on the PTI (which would normally have the effect I've already got of passing the call to the phone), and then select the "hands free" option, it does what it should and routes the call through the car. Effectively, it's as if the system starts in "privacy" mode rather than "hands free". Once I've done this once, subsequent calls work fine, routing straight through the car, but only until the ignition's turned off. The next time I start the car up I'm still paired, but calls go through the phone again.
If anyone's got any suggestions, I'd really appreciate them.
Thanks!

Try this
Had similar in a BMW...
Try www.jetwaremobile.com

Thanks, did try that but didn't seem to help, it seemed to be more geared towards additional functions like phonebook syncing rather than just getting a working connection in the first place. Maybe I'll give it another go.

Thanks TangerineTractor!
I fixed the problem I have with car kit of OPEL ANTARA using the software you said. It works disable sending Phonebooks.

I am having a similar problem with Wizard Mobile 6 cooked ROM. Before with the official O2 ROM on my Xda Mini S, it worked fine. The car would automatically recognise the phone whenever in proximity, and all calls would go through the speaker.
Now, I have to press the car kit's button (Nokia Bluetooth) each time I get in the car, to tell it to search for devices - i.e. the phone doesn't automatically announce its presence.
So, is there a different Bluetooth Stack we can try?

My Orbit works fine with my Nokia CK-7W using a B&B ROM.

Thanks, and yep that's the same car kit I have.
When you get in the car, do you have to do anything, or does the car kit automatically detect the phone? Mine doesn't since getting the Wizard Mobile 6 cooked ROM.
Do you know what Bluetooth Stack you use, and if I can download it anywhere for the Wizard?

No, just switch on the ignition key and away it goes. Also if the car kit is set as the default hands free if the phone rings it should try to connect to the car kit.
The radio I am using is 2.95.90 I have no idea what bluetooth stack it is, Tom Codin cooked the ROM, he will know.

Okay thanks. Does anyone know if the BT Stack is part of the Radio ROM? If so I'll just try a different Radio ROM.

Simultaneous Bluetooth connections on 8525

For the short time that I had the 8525 with the Windows Mobile 5 it came with, I was able to have my bluetooth headset ON (either during a voice call or just on standby) and to use ActiveSync via bluetooth simultaneously. Now, after flashing to the official AT&T Windows Mobile 6 ROM, only one bluetooth device can connect at a time. It's very frustrating to have to
switch one device off to use the other. I know that the phone supports multiple simultaneous bluetooth connections, but it doesn't seem to work on WM6 now. Any ideas?

Same problem here.
I can get my headset and GPS to be recognized simultaneously but as soon as the headset is initiated for a call, in or out, I notice my GPS apps start reporting there is no GPS device.
I've tried many things in an attempt to make it work but nothing helps.
The only thing I have not tried is a hard reset just on the chance it is a piece of loaded software causing the problem.

[APP] Auto A2DP ( Auto connects the a2dp on car radio )

I wrote this application because when I get into my car it only connects the bluetooth handsfree and doesn't connect the a2dp automaticly. There is an application that connects the a2dp by pressing a button, it's called a2dp toggle. You can find it here:
http://forum.xda-developers.com/showthread.php?t=437726
My application runs the a2dp toggle command line options to connect the audio to a car radio when the mobile gets connected to the radio for handsfree.
Before you install my application make sure you have installed a2dp toggle. Just install the cab file. After the installation you can start the service with the "Auto A2DP Manager" found in programs, you can also stop the service here. It also starts the service at startup of the device after the installation.
The CPU usage is 0.1% on average and memory usage around 300k.
Let me know if you have some extra idea's.
I like to thank te people that made A2DP Toggle and Pavel Bánský for his windows mobile managed service, his blog can be found here.
[UPDATE 4/14/2009]
I just found out that I have put the location of a2dp toggle hardcoded, so this version only worked when you have installed a2dp toggle on a dutch windows mobile on the device.
This is fixed in the new version v1.0.1.
[UPDATE 4/14/2009]
There was another bug in the application, it seems that there was a little problem with the application link. This is fixed now. New version v1.0.2.
[UPDATE 4/27/2009]
The application has some problems in windows mobile 6.5. It seems that the service runs correctly, but the manager doesn't work.
So in windows mobile 6.5 install the application and soft reset the device. It should then work. Don't use the manager in windows mobile 6.5, it creates new instances of the services and cannot stop them. After a reset they are stopped.

sweet! thanks man - i'll give it a try later 2nite. Wonder if it will work with MSVC, hmmmm

Hello
Cool idea, but it will not work for me.
I want to use this App with my XPERIA and my Car Handsfree "Funkwerk EGO Look". I start the Car Handsfree and then I switch on BT on my XPERIA after a longe Time ago (because the XPERIA BT is very Bugy the Bluetooth connects but the A2DP connection does not appear. If I start it with the A2DP Toggle tool manualy then it works.
Does this app only work on Blackstone Phone?
Bye

bug
no it should work on windows mobile 6 but I looked in to it and found the problem I will fix it and upload the new version v1.0.2, I will do it now.
[UPDATE]
You can download v1.0.2. now

Hello wian007
Now it works, thank you very much.
This Workaround is what i'm looking for a long time, now I can simply switch on BT and play Music in my car and a other affirmative effect is that Bluetooth connects much quicker.
And over again, thanks for you great Work.
Bye

Hello wian
I am again
I am searching a solution to execute a command to pause my MP3 player if A2DP is lost for 2-5sec. I want to do this with a Mortscript, do you know how is it possible to read the state of A2DP (established or not)?
Is there a Registry entry?
Bye

checking the a2dp state
to check the state me the a2dp I used the window mobile state class that comes with the framework. so I think you could find it in the registry but I'm not sure.

I was just wondering about this...
Great work so far.
- Anthony

Quick Question:-
Are you looping to check the connected devices, or are you using RequestBluetoothNotifications from coredll.dll?
-Anthony

no I'm not looping. it is based on events that get fired when a status in the status class of windows mobile sdk changes. I used managed code to write this application.
But maybe I should rewrite it in unmanaged code and intergrate the functionality to connect the a2dp, instead of using the external application a2dp toggle.

quick question-must my car radio have Blutooth?

Is your app able to transmit music/navigations commands to my bluetooth car kit? In stock my ROM is not able to do so.
My old symbian devices where all able to to that. But with windows mobile all is different.

I'm with HD with v3.0 duttys rom and cannot get this thing to work.
Any solution??

Yes, to make this application work, you have to be able to mannualy connect your mobile with your car radio to have your sound on your car speakers.
Also your car radio must connect as an handsfree control device. This triggers the making of a connection.
If you cannot make a connection with your carradio by running the a2dp toggle executable my application will also not work because my application runs also the executable.

My application doesn't provide that functionality. My application runs a2dp toggle when a handsfree connection is made.

Can you post the last lines of the log file "a2dp.log" that has been created in the root of your device?
And does your mobile connect when you run ad2p toggle?

Hope this isn't off topic.
Has anyone seen text messaging work through a Windows CE device to a head unit?
I had a Sony Erricson W810 and the HFP/A2DP worked as did the messaging push to the car stereo. (I have a Kenwood DNX7120 with BT). Could read and respond through the Head Unit...I know a bit dangerous..but the technology worked well.
My symbian (N95) devices worked fine with HFP and A2DP, but not message push either.
My current device (Sony Experia) works great with the HFP and with A2DP profile but again not with messaging.
Just currious...cwh

It has a more lines, but they are all the same as these two lines
If my mobile connect when I run ad2p toggle?? My device when I plug the key into my car, automatically connects to the car kit bluetooth. No need for any intervention.

Yes ok, your handsfree is connected but does your mobile connect with bluetooth stereo if you run a2dp toggle. It seems that this doesn't work.
So the only solution that I can think of is that you need to set your radio as stereo output in the bleutooth connections. Then test if a2dp toggle connects your phone to the radio. If so restart the device and it should work.

Handsfree
I use Plantronix handsfree when I'm away from the car and a Parrot handsfree in the car. I want the Parrot handsfree to take over automatic when use the car.
Do anyone have the solution ????

Can't pair my BA with GPS Navigator

Hello!
I have a car GPS Navigator which has a feature to pair with a mobile phone or PDA via bluetooth to use it as handsfree, view contacts, make calls from GPS screen ans so on. Both devices can see each other via bluetooth but the problem is that they can't pair. My BA has WM6.1 installed, I haven't any problems with bluetooth yet. May be BA does't support this functionality or it does'n have appropriate Bluetooth Profile ?

May be it would be useful to someone with similar issue. My bluetooth problem has been resolved just by installing WM6.5 ROM ! I've tried almost all versions of WM6.5 located on xda-developers and every one has the bt stack much better than WM6.1 has.
