If i have paired with f.e. my carkit, and after that i UNcheck my bluetooth to
"visible for other devices": does it then still work with my (already) paired carkit?
also, is there any way to save battery-power while still having bluetooth enabled for my (paired) carkit?
This is the only bluetooth-device i use.....
The diamond has a very low battery-performace, thats why i ask......
Thank you group!
The visibility should make no difference if the device is already paired and set as authorised. Its this was on every SE and Nokia I have used. Even for connecting to my Mac.
As long as its already set up it should still connect.
thank you for your answer.
visible = pairing mode, i.e. setting up new pairings. No effect on existing ones. (And wont change the battery life, since its not sending a signal but waiting for the other device to say hello first.)

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.
I have 3 stereo bluetooth devices and 2 headset only devices.
The problem comes from auto re-connecting to the stereo devices.
The only way it seems to work at all is if I pair all the stereo devices first.
If I reset, then I usually have to click and hold on the device in BT Settings and select "set as wireless stereo" to get the stereo connection to kick in.
In my tests I have made sure only one device is on at a time.
It certainly is not as easy as it should be.
It seems to be worse after a Tilt reset.
So my questions are : Has anyone else seen this behavior and is there a fix or work-around for it?
If not, does anyone no how to make a direct link to the BT Settings Window so at least it would only be a couple clicks to fix it?
You need at least one of each device (headset and stereo headset) to see this problem.
I've seen this with my Wizard as well as the Tytn II, so I suspect it's a "feature" of the MS BT stack. I think it's somehow related to the "set as wireless stereo" feature -- apparently only one device at a time can have that setting, and MS turns the setting off if it can't connect to that device. Note that there's no such setting for handsfree, and connections on that profile work flawlessly between multiple devices.
Its a little better
What I found out is that if you pair all your stereo devices first and then all the non-stereo, things seem to work a bit better and Dutty's BT-Link plugin will reconnect the stereo part most of the time, so its only a click away and sometimes you don't need to turn the device to discover mode.
However, if anyone from MS reads this, there is no reason not to automatically connect into full stereo, IF the device is the only one in the list that can be found at any point in time. And if they wanted to be really cool, if not, then present the user with a list so he can click to choose.
Similar problem
Hi BSW11,
Im having a similar problem with the pairing of my carkit.
http://forum.xda-developers.com/showthread.php?p=1717330#post1717330
I believe it can be traced to the the MS BT stack not handling the automatic re-pairing correctly. I am surprised that not many other people have notice or complained in this forum about it.

No BT Wireless Stereo device will auto-connect to any WM device, you have to tell your phone to connect to it via the BT setting unless a 3rd party app has that function built in to it. This is a 'feature' of MS WM OS system.
Any BT 'headset' (ie mono earpiece) will auto connect if it has been selected for 'use as headset'
Hope this helps.
Hi, I'm pleased to say that setting up my TyTN II to sync via Bluetooth with my laptop running Vista's Windows Mobile Device Centre was a doddle. None of the nonsense I had before on WM5 and my Wizard.
However, it appears Bluetooth sync needs to be invoked manually each time from the TyTN. This makes this lovely feature next to useless.
With Nokia PC Sync for example, Bluetooth sync to a Nokia phone can happen whenever the phone comes back into range, or every 15 minutes if you so choose.
So, is there any way to specify this with Windows?
I don't think so at the moment. It's a problem within the Microsoft WM OS.
I too used to love my old Nokia 9100's capability to do this but with having so many connection variants on this unit (GPRS, WiFi and BT) Microsoft have probably opted for a safe solution.
At least with manual select, you wont have it running down your battery with lots of data traffic while its in your pocket/purse at home/work without you knowing!
Maybe we could pass this on to the Kaiser Tweak guys to see if it could be made selectable?
Worth a try!
Sure, can you do it?
Will have a go but my 'Street cred' is a little low here at the moment....
I hope one of the other patient dev guys may look at this and take it up???
your not alone
Check out these other threads. All describe different problems people are having (including mine - not being able to automatically re-pair with my car kit).
All seem to stem from the auto re-pair problem.
If a developer could help, that would be great.

Many thanks.. I've looked at those and they are mostly concerned with BT connection to audio devices.. What we are looking for is an automatic polling of your device by Activesync over BT as PCsync used to do for the Nokia. The connection has to be initiated by the SW for it to work. Cheers anyway!
Sure, they are mainly about audio, however (at least in my case) the audio is perfect when its paired.
My main concern is exactly the auto polling. I can pair my device the first time to the car kit, but every time i get back into the car I have delete the pairing and pair it manually again. This is not how bluetooth should work.
I think this is very similar to the problem the author of this thread describes.

Yep, my BT audio is good and you never know, if we start looking at auto-polling of data/stereo devices we may cure a lot of problems on here..
Thing is we may have to go around the Activesync overide (which is the slowest block on this setup!) and use a priority connect to BT similar to WM5torage on usb!
What ya think XDA???
Yeah its one of the few things I miss about my Nokia 7710 was that i walked into my house and it would sync with my computer automatically. sigh
Its definately a WM/Activesync 'Non-feature' as when you first pair your device to an Activesync capable BT PC or laptop you get a pop-up message on the WM device reminding you to disconnect your BT Activesync link to avoid draining your battery!
Hi guys,
I have an X1 and a new Nokia6600 slide.
I have them both paired to my laptop and car (which have both bluetooth built-in) Both of the phones have bluetooth enabled and are always visible, all options to disable bluetooth or to stop being visible are disabled.
The biggest difference is this....
When I turn on my laptop or step into my car, my Nokia says, look I found your laptop/car, you're now connected! (without me doing a single thing)
My X1 is like ".........................." nothing... I have to manually enable the connection via for example ActiveSync, and chose to connect via bluetooth and then everything works fine.
I checked every setting concerning bluetooth or security and everything but I just can't find an option to make my X1 act the same as my 6600. It also doesn't matter if I just turn off the 6600 and have only the X1 turned on.
Maybe it is a setting, maybe it needs some tool or something.. I hope somebody here can help me or point me into the right direction.
Thanks!
Hello!
I bought an SBH20, paired with my XZ via NFC, listened to music, then disconnected the headset, using the NFC.
After a while, i tred to connect again via NFC but all i get is a 'connecting' message, BT turning on -white BT icon- but no real connection, therefore the BT turns off.
After several tries it finally connects, but it's not reliable this way.
I noticed, if i enter to settings(not turning anytihng on/off) and trying to connect (still using NFC), everything works fine: connects, disconnects perfectly, and handles the BT as it should.
I've reseted the headset, tried single and multi point modes aswell. Deleted the BT devices, then repaired, still got the problem.
Am i doing sth wrong? I want to connect and disconnect the headset with a simple touch, and not toggling the BT manually (NFC yeah...) Is this something, SBH20 is not compatible with?
(btw sony support says: "For subsequent connections between devices that have already been paired once, make sure that Bluetooth™ is turned on so that the devices can connect automatically." If it's a "must" , then what is the [email protected] use of the NFC??? Just to pair once???)
Please share your experiences! Any advice would be greatly appreciated!
Thanks for reading ( and sorry for my english)
I actually have the same problem using the SBH50. For me sometimes it connects perfectly fine, other times it doesn't and I have to go into bluetooth settings after which it seems to connect properly.
I have noticed that it also depends on how I disconnect it; if I remember to touch the headset to disconnect then next time when I try to connect I have more chance of it being successful. Also, when I try to connect I hold the headset aganist the phone even after the ‘connecting’ popup until I get the 'connected' popup.
These are just work-arounds which aren’t always 100% successful though so would be good to find out what the proper method is.

It is a real shame... In my case it's the opposite, if i touch the headset to disconnect, the next nfc-connect tends to be less successful.
(and i noticed that it also matters if i turn off the headset after disconnected, or not)
And what is really odd, that i don't have to do anything in the settings menu ( or bluetooth settings) just open it, and everything works like a charm...( all connect or disconnect tries are succesfull, no exception, even if i push the headset repeatedly to the pohone's back)
I'm not affraid to mod some system files, apps, maybe build.prop tweaks, but i don't know where to start. In bulild.prop there are only a few nfc related lines (tried to enable/disble those)
So i'm not alone...maybe even more people are in the same boat, trying to solve this.
Again; any related info is welcome
I also have a sbh50 but i normally disconnect by turning off the headset. I have set it in smartconnect to turn off bluetooth automatically when the connection shuts off but it doesnt always do that.
It reconnects with no issues when bluetooth is on and i turn the headset on again. I use the nfc tap only for the initial pairing.
The only issues I have is the google music skipping issue that i posted the other day and the gmail smart connect not working on the sbh50

Well, then we don't have the same issue. I tought i could use the nfc for connect/disconnect (i actually still think it is capable of that, just sony messed up sth)
Could you try to connect/disconnect and connect again with your devices, please :angel:
I'm really curious about this whole nfc story ( why does the headset have the chip/tag if it only works for initial pairing -its not a big deal to pair manually, especially that it has to be done just once-, and on the other hand: if i put nfc in the device, why not put in this functoin too- not a big deal: a proper working BT toggle, but it brings a tad more functionality-
