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...

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.
hrm this isnt good - it would appear bluetooth stops working when wifi is enabled - was listening to an mp3 on bt stereo headphones and enabled wifi and it killed the conn - not only that it seems i cant use any form of bt device if wifi is enabled (not even connected) on the device - wtf?
is anyone else experiencing this?
No, I use Jawbone BT headset with all sounds out BT using BTaudio.exe then start WiFi on home LAN and watch streaming video from Slingbox.
this was the case with the titan...
eric b
do i have a faulty unit?
i don't think so. in the titan, the bluetooth and wifi antennae were the same actual unit.
eric b
you sure? remE says both work at the same time just fine for him :s
to me it seems as thought ewifi signal is overpowering the bluetooth or smt - does the bluetooth freq lie in the wifi freq range or smt? is there any way they could overlap?
both work if i have only one on at a time - can anyone confirm either way if both work at the same time for them and what equipment youre using?
I'm doing it as a type this. I'm watching 30fps video streaming at 300k over WiFi and listening to it thru a Jawbone BT headset. For sure this works fine.
I have a Hermes and it would not do this well at all, it would allow BT and 3G video streaming but not WiFi. Kaiser can handle it.
maybe you could try a differet BT headset, maybe yours suffers from inteference ( i don't know the frequencies of BT and WiFi but WiFI could be killing the connection because your headset jamms)
BT and WiFi are both spread specktrum radios operating at 2.4ghz. They are designed to co-exist and do so on Kaiser. Maybe there is a difference with Stereo vs Mono headsets, they do use different BT profiles. If I get a chance I'll try a stereo set and report back.
thanks guys - i need to make sure my unit is duff before i ssend it back for a replacement ;(
looks like my unit is gonna go back - i called htc and they said they havent heard of this issue before and are 'escalating it' - it seems that superetrader wont give me an RMA for my unit until htc have given me a reference number - is this normal procedure? seems a bit odd to me
i tested my unit some more at work today with a whole host of different bluetooth and wifi gadgets and the problem is consistently reproducable

Hi,
do you tried also a buttom to call with voice command application or a phone call ?
I've a HTC S100 and the sound is well but it's very difficult to start a voice commande or to recall last call because seem that the function "hand free" sometime is lose.

I have the same problem with my handsfree headsets an Tytn II (kaiser):
i have a motorola H700 and a Scalarider headset for helmets.
They are bot NON-ADP and thyey support handsfree.
Sometimes the button on them stop working and I can't do voice dialing with Voice command neither repeat last call.
They appear as connected and If I manually call a number they work.
To get the button works again I have to restart the phone.
Maybe a fault in the microsoft bluetooth stack?
Also: my Motorola H700 has a flip and when you open it the headset turn on and get connected.
You should be able to answer phone calls by opening the flip.
Sometimes it works, but most of the time it doesn't connect if I open it while the phone is ringing and in that case I have to restart bluetooth connection to make it work again.
Microsoft or HTC should check end improve bluetooth stack!
Any hack around?
Can't we put the broadcom instead of microsoft stack on kaiser?
I wrote to HTC Support about this problem and they answered :
"Customer email address:XXXXXXXXXX
Good Afternoon,
The multi function button is the one small button with the led light in, not the big play/pause button.

Astonished!
Amazing answer!
Are they idiot?
I'll write them too,
I hope someone cleverer will read the my mail
and suggest the bug to the technical stuff.
I have a motorola H350 and have been experiencing the same problems. It's driving me mad. The problem makes the use of the hands free totally useless as it seems to stop working at the drop of a hat.
What I've found so far.
To get it working you need to turn on the ear piece.
Then turn on the bluetooth on the phone.
If you do this any other way it doesn't work. Once it's working you may or may not be able to hang up with the button. If that's the case it won't answer with the button either.
Once it's working it seems to work ok till either the headset or the phone's bluetooth is turned off.
Voice dial will not fire up until the main procedure if followed and sometimes it takes several tries.
I was wondering if this was something to do with the motorola but seemingly it's to do with the stack so getting another device isn't going to help I guess.
The bluetooth worked perfectly on the Hermes but immediately I got the Kaiser one thing alerted me to the fact that something was different.
With the Hermes, as soon as I turned on the bluetooth and the earpiece the phone would alert me to the fact that the motorola wanted to connect.
With the Kaiser nothing, even when I searched for a device. I had to find out how to put the earpiece into search mode before it would find it.
Very flakey and very disappointing. I hope someone finds a fix for this.
Anyone else experiencing these problems?
I've got an H700 and Jawbone. I do notice more crackle type sounds and lower volume on both using Kaiser compared to my 8525. The H700 connects within 1-2 seconds when opening it's flip and I have noticed that on occasion, if I walk away from the phone (eg. phone on desk) the headset may not reconnect when I return. The Jawbone has been fairly good at connecting and staying functional at all times but the volume is lower as noted by many people.
I would say that the stack overall is better than the 8525's for all the devices I've tried (3 headsets, 2 Laptops, 1 Garmin Streetpilot with BT Phone interface)
I am also losing the Voice speed dial & redial button from time to time. It also worked that way with my hermes, so I kinda get used to it...
I am now wondering if it is related to my BT earpiece (nokia bh-200 or something like this) of if it is the BT stack which has never been really working on all the device I could test (hermes, trinity, kaiser).
I allmost never had issue recieving call (I don't recieve much call while using the BT earpiece) but it is sometime impossible to initiate a call through the BT earpiece.
The simplest way for me to lose the voice recognition is to:
-Start BT on the phone
-Start BT earpiece
Phone recognize the earpiece, everything is fine
-Restart the phone
Phone & BT reconnect, but voice recognition & redial are gone
I would really appreciate of some of you could test my little procedure and report if it works of not. If it is working for some other BT earpiece I may change mine and get rid of this eternal annoying issue.
Thanks
Jabra BT500
I have the Jabra BT500 and same problem with the TyTn II.
The earpiece can't initiate a voice call...
Looks like HTC (or Windows), starts to deliver ROMs like Mr. Bill Gates does with his M$ crap...
If someone find a solution for this Bluetooth problem, please post it!!!!
Thanks a lot,
Kaiser and Moto H700 just do not work together
I also have a problem with the Kaiser and a Moto H700. The M700 button stops working randomly, the BT connection sometimes disconnect during the call at will.
I can still use H700 successfully with my old Nokia 6680, so the problem clearly is in the Kaisers BT stack.
I’ve made the BT update that HTC posted just recently for TyTN II, but it had no effect.
Fortunately, I have my old Moto H500. This one is working OK with the Kaiser, but. Like it was pointed here before me, the only way to get it working you need to turn on the ear piece. Then turn on the Bluetooth on the phone.
In case if the Bluetooth connection was disrupted for some reason, the only way to make it work is again swath Kaiser BT off then turn on the ear piece and switch on the TyTNs BT.
The Kaiser’s BT stack is not good also connecting with a PC, the connection is just not stable.
Just wanted to chime in and say I've had the exact same problems with my Tilt and Motorola H700 as various people have described here. I posted about it on the AT&T forum too, and no one there has any working solution either, AFAIK. I too tried the "fix" from HTC, and to no avail.
This is a pretty big disappointment for me; I love my Tilt, but Bluetooth is not new technology, and it's really inconvenient that it works so poorly on this phone.
Motorola headsets seem to have a problem with this device. I had trouble getting my H500 to connect and the voice button to work. Once I reset the phone when the headset was on and it wouldn't connect. I tried deleting and re-pairing. It took another reset to get it back. Fortunately I don't use that headset anymore.

The same problem.
But this time with the Sony Ericsson BT HBH - DS980.
I also put the "fix" from HTC, I gave them back and they change them with another brand new Sony Ericsson BT HBH - DS980, but the problem exists.

I just bought the same headset... cant get it work with the TyTN II - Kaiser but pairs without any problem with my TyTN I - Hermes... clearly it is the BT Stack
Way beyond my abilities, but cant the BT stack on Hermes be cooked into a rom for the Kaiser ?
I have a Motorola HT820 and a Motorola S9 both devices are working flawless with the kaiser.
Now i own a motorola S705 too , with this device my kaiser suddenly turn the bluetooth off (

Hi all, I have had this bug in varying flavours with both the Wizard and now the Kaiser.
If I make a call via Bluetooth (certain devices only e.g. JVC in car stereo), after the call, all audio is lost on the device when using the speaker, e.g. no ringtones, no TomTom voice guidance. (Oddly the touchtone sounds on the phone dialler continue to work.)
Making another call via Bluetooth works fine and all audio is heard, but not if calling via the earpiece of the phone - all phone audio is still muted. A reboot is required. (Even after a reboot, sometimes all audio is muted, and 2 or 3 reboots are required.)
It is like Bluetooth is 'stealing' the audio from the phone's speaker (which is should), but not giving it back at the end, however turning off Bluetooth doesn't return it.
It happens with WM6.x on the TyTN II.
If you can fix it either via a workaround (reboot the audio service after every call?) or a direct fix (HTC are useless and have not emailed me back), I will pledge you $100 via PayPal. I am sure others will join me in pledging an amount also.
Yes. I've seen the same thing with the last stock Tilt ROM, too.
Same here. But is not happening very often.
The other issue for me is if I have A2DP enable and listening to music, then making a phone call will drop the A2DP connection and I have to reconnect A2DP again. It happens to both my JVC car unit and Sony HBH DS220.
I tried that w/ Dutty's WM6.0 and the latest 6.1 rom
I have the same issue, with bluetooth disconnects.
Just staying on-topic here (you can solve A2DP issues with A2DPToggle a great free app), has anyone found a solution to this Bluetooth loss of speaker audio issue, or a workaround to avoid it happening?
Rebooting the phone after every Bluetooth phone call is hardly what I consider a high-end smartphone to require.
Same here
What Radio's are you guys running? (Ignore my signature for the moment, been phoneless and away from here for a while and just getting back up to date )
Haz
My current radio is 1.64.08.21.
I have also tried 1.64.06.04.
Could we be closer to finding the problem? Does the Radio contain the Bluetooth stack?
Here are all available Radios:
http://wiki.xda-developers.com/index.php?pagename=Kaiser_Radio
I'm going to try 1.58.26.20 now. I suggest others try the other 1.5x variants and report back if any of them solve the bug.
Update: I am now offering $100 to anyone who can fix this - see 1st thread.
I have used Windows Mobile since the first ever SPV phone. This one issue is making me look seriously at abandoning that loyalty and getting a Blackberry. If I can fix this for $100 I could be tempted to stay however.
Have you tried BT Audio Toggle ? (found at http://pdaphonehome.com/forums/sams...luetooth-headset.html?perpage=20&pagenumber=1)
Maybe if this helps with your problem then a mortscript could be written to automatically run the utility after a phone call.
What bluetooth headset do you have? Have you tried other headsets or just the one you have? What version of 6.1 are you using?
Thanks, I'll give the audio toggle a go. Might need some help with Mortscript though
I am using the JVC KD-BT1 car stereo with Bluetooth in-car kit. However I can also lose audio on a clean boot even when not in the car, although that is very rare. When using it with the car stereo, it happens after almost every call.
I am running Sleuth's WM6.1 but the other people in this thread are using a variety of BT devices, ROMs, and HTC models.
Can anyone help with how to create a MortScript to run BTAudioOff.exe after each phone call?
Flash a NIKI radio. I had a similar issue with my JVC in-dash CD player and I just got all the radios and tried them all. All the NIKI radios seem to work a lot of the time, while some work and others don't.

Okay I tried this and before I even got in the car, chose to turn Bluetooth Audio off using the toggle. Since then I cannot recreate the issue! I am not having to toggle after every call, I only did it once and the problem won't come back!
Fingers crossed...
NP. 1 more thing. What do you mean all audio is lost? Do you mean that the auido goes through the bt device? Or just that there is no audio coming from either at all. If that's the case, then all you might have to do is go to Comm Manager>Settings>Bluetooth>JVC (or whatever you named it) and uncheck the Stereo sound and viola it should work unless you are not using A2DP >.> . I think it's either directing all sound to your bt device or trying to send sound to it but failing.

The issue is there is no audio coming from either the phone or the Bluetooth device. I hear the Bluetooth device disconnect, and its display shows that it has also.
I see no 'Stereo' option to untick for the JVC in its Bluetooth settings, only Hands-free and Wireless Stereo (already unticked).
No progress
Okay, this is seriously getting me down now It all sounded so promising. I have tried the following:
Flashed Niki Radio 1.58.21.23
Tried using Bluetooth Toggle - it seemed to work once when I turned BT off before connecting, but after a reboot the problem is back
Tried a HFP extension PM'd to me (thanks anyway - didn't help)
Made sure Bluetooth Stereo is unticked in the JVC's settings on the phone
I am not sure if the problem is worse when taking a call as TomTom is running.
Here is an interesting development which might help someone narrow down the cause:
I make a few calls, and as always audio is lost, even for phone calls sometimes.
Touchtones on the keypad are the only sound that the phone continues to emit itself. Everything else (TomTom, ringtones, etc.) is dead.
I then go into the JVC's A2DP mode and 'Connect'. The icon appears on the mobile's title bar, and I can hear phone audio through the car stereo.
I 'Disconnect' and the phone's audio is still lost.
What this tells us is that the phone is putting out sound, just not through the speaker.
If someone can write something that will reset the speaker driver after a call, my offer for $100 still stands.
Just to update this, the issue still exists with a clean install of HTC's new 2-May-08 WM6.1 ROM from their website. To***rs!
CJSnet,
Since we got the similar setup w/ exact the same issue (Att Tilt w/ JVC BT-1), I think the problem is basically Kaiser does not switch back to A2DP profile properly after headset profile from phone call. The same issue happens to my Sony HBH DS-220 stereo headset too.
I tried my Eten M600 w/ JVC BT-1 and does not see this problem
I found a problem with my kaiser phone last night. The problem is that if I listening to music with my bluetooth headset I am not able to connect to my WiFi at the same time. This problem is specific to A2DP because my headset can be connected to my phone and I can not browse the web with WiFi. Has anyone seen this problem before? Has there ever been a resolution for it?

I've seen this too -- when using A2DP, the WiFi connection goes down & won't re-establish itself until I turn off A2DP. I haven't found a resolution yet -- not that I'm looking for one as I almost never use A2DP, and when I do, I'm in the car, where WiFi isn't too useful.
See my post here which may be a related problem. I assume you have the same new HTC ROM: http://forum.xda-developers.com/showthread.php?t=396409
I have a similar issue. If I am streaming music, from my HP media server, over wifi and using my Plantronics 590A bluetooh headphones, after each song I am asked to log back onto the network and as each song comes to an end my device starts to search for a network connection. I don't have this issue when I use wired headphones. Clearly there is an issue when both bluetooth and wifi are used at the same time. I don't know if it's hardware or software but I'm not happy about it.

HTC TyTN II (Kaiser/P4550)
Rom ver: 1.82.707.0 WWE

It's normal. Without going too technical, WiFi and Bluetooth operate on the same frequencies. They will live together if they're not using too much bandwidth, but if the usage is heavy there will be problems.
A BT stereo headset represents a lot of data to send and thus bandwidth usage, which means the BT will use the spectrum heavily, stepping over the Wifi. Due to the many packet losses the Wifi connection cuts.
Other way around, if Wifi is under heavy load, Bluetooth might drop.
Nothing we can do, that's what happens when you pack 2 radios operating in the same frequency band so close to each other, or even maybe sharing the same antenna which might be the case in today's phones.
It is absolutely NOT normal. The reason I know this is that VoIP over WiFi has been running almost perfectly on my TyTN II for a year, until I installed the latest ROM by HTC which broke it.
I used to get no crackle on Bluetooth calls with WiFi turned on. Now I do.
I used to get great quality VoIP. Now it is beyond unusable.
Simply, their new ROM broke it. BT and WiFi used to live in harmony, until their buggy ROM came out the other day. I think there are many users who know this, and who expect a hotfix soon.
You're talking about calls, I assume using the BT headset profile, while the other people in the thread are using A2DP wireless stereo. They're very different in terms of bandwidth.
On mine the headset with WiFi is also fine, but not A2DP. You're apparently not having the same issue than what is mentione in this thread. Yours might be due to the ROM, but the A2DP thing is more likely to be related to what I explained. I could myself experience it with several ROMS (all WM6, never tried a 6.1).

Nothing we can do, that's what happens when you pack 2 radios operating in the same frequency band so close to each other, or even maybe sharing the same antenna which might be the case in today's phones.

My old TyTn II worked fine with BT and WiFi on at same time - never a problem. I always had WiFi on at home for emails etc... and always have my BT headset (Plantronics 8XX mono) working as I hate holding phone to my ear and get a lot of calls.
I recently bought another TyTn II and then unlocked it using advice form this forum (many thanks to all BTW!) and installed latest HTC rom and WM6.1 etc... Now I love many aspect of the new ROM but I can't use BT and WiFi at same time.
So from my experience it MUST be the new HTC ROM software issue.
Okay, chalk me up as another victim of this Wireless + A2DP = Crap Reception. I've tried three other Radios and the effect is the same.
I was using a rom I got in about April, and I could stream music from the internet over wireless listening to it on my Pantronics 590A's over bluetooth no issues (other than battery lol). Now with a rom I got this month, I can listen to music over bluetooth no problem, surf using wireless no issue but as soon as you mix them both it's all bad. Also, I need to re-pair my headphones whenever I want A2DP, where previously I could just turn on the headphones and have them connect. Also, no headset icon in the taskbar.
It's not a CPU issue as there's no excess usage when you both have them enabled. Personally I'm going to point the finger at the bluetooth stack here.
As far as I remembered when I first purchased the ATT Tilt with my Plantronic Voyager 855 I WAS able to stream via Wifi (Winamp Remote) and use my bluetooth without a problem. It's when I started to put cooked roms in the Tilt that it stopped working correctly...
Besides, I use a Macbook Pro via Wifi only and I listen to my Itune via my Plantronic Voyager 855 everyday. If it's true about WiFi overloading Bluetooth on the frequency. Why does it work fine on the MBP?
And Finally.... to make my point...
I also have an AT&T Fuze. Works fine there. Matter affact. I'm currently connected via bluetooth to my Fuze with my Voyager 855... turned off 3G/HSPDA on the Fuze. WiFi on the Fuze using Winamp Remote to connect to my PC streaming from there. Explain that....
Has anyone fixed this problem?
I'm experiencing the same problem on my kaiser aka xda stellar. When Wifi is turned on bluetooth A2DP stereo connection is dropped.
