Bluetooth GPS want to re-pair all the time

Hi folks,
I upgraded my Hermes with Schap's Windows Mobile 6 ROM. Works fine so far. But when I try to use my Bluetooth GPS it acts strange.
I paired the Bluetooth device and set up a COM-port for the applications. The first time it works. The next time, when I switch on Bluetooth and start for example TomTom, the Hermes tells me there is a new Bluetooth device that wants to connect. I checked and found out the GPS is still in the list of known Bluetooth devices and the COM-port is set. But the assistant is still bugging until I add the "new" device. After that of course my "old" device is gone.
How can I avoid this? Anyone experiencing the same problem?

I have the same issue, really annoying so would love to know the answer

On your Hermes:
Have you tried to checked off: "Make this device visible to other devices"?
Under: Start\Settings\Connections\Bluetooth\Mode (2nd tab on the bottom)
Option #1 (Hermes)
~If, "Make this device visible to other devices is not enabled, delete the pairing for your GPS.
~Check off "Make this device visible to other devices"
~Pair your GPS again (ensure that "Make this device visible to other devices" is still enabled)
Option #2 (GPS)
Don't know what kind of settings for bluetooth you may have on your GPS. I found for my car stereo, that I needed to leave it, in the "waiting/open for connection mode.
Now when I turn the car on it automatically connects the phone and stereo off my Hermes.
What I'm basically saying here is there may be a setting to leave your GPS automatically open for bluetooth connections?
I think option #1 may do the trick....
Hope this helps! Good Luck!

If your concerned about Security you can always change the Pairing codes.
and or turn off bluetooth when not needed.
I'm unaware of any cases where one can connect unless there paired, so in most cases access needs to be allowed on both ends, usually needing pairing codes. Even if it is one way, an approval code will still be needed.
What I found is this, if you want automatic connecting with one way pairing codes i.e. (Car Stereo to PDA or GPS to PDA) You'll need to allow "make device visible" checked off. The usual cause is a memory storing issue with the GPS or Car Stereo. I know that on high end Stereo's and GPS's they have on board memory which will save connection settings, where you'd put pairing codes on both ends and it will save the settings, thus negating the need to leave visible.
Don't know if I answered your question?
Hope I was able to shed some light on the subject....
Good Luck!

Sony BT-2500 and Touch

I have a Sony BT2500 bluetooth headunit in my car and I paired my Touch to it without any problems. The only issue I am having is that when I get back into the car it automatically re-connects the phone BT function but will not automatically reconnect the BT Stereo/AD2P function. Is there are way I can set it so that it will auto connect both?

I saw this on another forum, the op stated that if you press the number 6 on the head unit it will cause your bt-2500 to activate the bt audio connection with your touch. I haven't tried it yet, but will when I get home. I've always had to go into BT settings on the touch and hit refresh so I hope this works.

I made the same mistake. For six months I though it was not compatible according to some of the reviews. Then one day, out of boredom, I read the manual. Yes, I supposed to press number 6 when I get in the car. There is the saying "Read the f* manual". Amazingly how many time I found this true.

Bluetooth bug.

When I connect to the car stereo, I set it to phone only, not media and it works fine, ouputting the sat nav voice via the phone. When I reconnect, it again connects both phone and media. It's driving me mad, any ideas?

I connect to my Parrot MKI9200 car kit and have no issues like this, it always connects for phone and voice from CoPilot comes out of the phone. I haven't changed any settings

That's interesting - does the parrot support music streaming? Could you check the settings of the connection please? If you tap and hold where it says Parrot, it shows which services are connected.

Just checked... The only part that is ticked is phone. Media is not ticked. As I don't stream media from my phone to my car kit, I don't want this ticked. If I tick the box, CoPilot alerts actually come out of the car speakers.

Yours works the way I want mine to. For some reason though, even if I turn off media, the next time it connects it will connect both media and phone. Weird.
Again, thanks for your help. I'd really like to find a solution to this, it's really annoying.
One thought - is yours a sim free one, T-Mobile or Orange? Mine is T-Mobile.

Mines sim free. What Car Kit do you have? Might be something to do with that?

It's an Alpine 400bt, which is an add-on unit for Alpine stereo's, in my case a 9887r. The bluetooth unit is actually made by Parrot I believe.
It could be something to do with it, however it used to be OK using Windows Mobile.

another bluetooth question
I see you guys mentioning some bluetooth settings in the posts above - where are they found?
I have a problem that once connected to my car phone system by BT, the keypad in the car stops working which means I can't respond to voicemail etc. My other phone is a Touch HD which works fine.
Are there settings to select different profiles like you can with Win Mo?
I'm new to Android and all I can find are the HTC settings under Settings\Wireless Controls\Bluetooth Settings but these don't help
Thanks in advance
Edit: just reread and see I need to tap and hold the connection, so I'll try this later...

[Q] Bluetooth Pairing Every Time I Use it

Not sure if anyone else has this issue, but every time I turn on my bluetooth headset, I need to pair it. Have never had this issue with any of my other phones. Any ideas? My phone is stock, rooted with tethering hacked. I have disabled some bloatware, but nothing related to bluetooth or connectivity. Is it possible bluetooth is somehow connected to some stock LG Bloatware I am not aware of? thanks all!

I too experiened the same problem a while back till I installed "bluetooth auto connect" (free from google play store).
Hope this info is helpful to you.

Help paring will not connect to audio just phone works.
My LG G2 will not stream music to my car. The phone Bluetooth works just fine. When I move to connect to the media streaming the car say no Bluetooth audio device connected. The car is a Mercedes E 350 2010. I had a nexus 4 also an LG phone and I had no issues streaming. I am aware of the menu that you can get to check the boxes for phone audio and media audio. I have tried every option I can think of with no luck yet. So far I unpaired the device, I factory rest the phone all to no avail. When I attempt to pair just the Bluetooth media to the car the car asks me to up in the pass code and I do then the phone asks for the same code. This lets me know that the 2 devices are communicating. Once I have entered the pass code the car says connecting….. then is says connection to Bluetooth media device unsuccessful called LG T-Mobile and Mercedes and not one of them has any idea that was helpful or I had not tried yet. . I am rooted but running stock. Have 2 headsets that both work fine streaming music. Any ideas would help.

Tried resetting the car radio? My alpine will only store info for 3 devices then it will ask for that code and won't connect until at least one spot is cleared.

Not a bad idea. It is a stock system so I will look up how to reset if that's an option.

If you can't figure out how to reset radio, disconnect your car battery for a minute then hook it back up, should clear its memory

Problem solved. Both my Ipad and LG G2 needed the set up to be requested from the car. You must use the cars external authorization set up process not the normal way you sync your phone to make calls.

[Q] Help with Bluetooth

Hi Guys,
i recently upgraded my S4 to a S5
My S4 connected to my car stereo as phone and as multimedia device, but my new s5 just wont connect as multimedia device.
It functions fine as telephone, but i cant get the multimedia option checked.
Is there some hidden option somewhere i'm missing ?.
I didn't have to do anything special for my S4 to connect as multimedia device.

Unfortunately you didn't give us any details of how you tried to pair your stereo to your phone. So we have nothing to work with, no way to point out a missed step or error.
Did you choose the appropriate pairing mode in your stereo menu? If you have continued difficulties, you should tell us what model your stereo is, your S5 firmware version and a detailed description of the steps you tried.

Unless your car stereo is A2DP compliant your phone wont use it for multimedia. Check that out.

This is driving me crazy.
I've spend a couple of hours now in the car trying everything i can think of.
A google search learned that I'm not the only one with this problem.
Clearing the Bluetooth cache didn't help, i installed this app but that didn't work also.
I popped my sim back into my old s4 and it connects perfectly as both phone and multimedia device, allowing me to play music from my phone on the car stereo system.
The car is a Toyota Prius 2012.
I've attached the specs of my new S5.
The S5 only connects as phone and not as multimedia device.

I also experienced BT trouble with S5 in my wife's Prius 2012. My iPhone connects with no problems, phone, multimedia, internet.
I tried to share S5's Internet but after asking/reading here found out that a vital file is missing, /system/bin/pand.
The reason why you don't get MM connection could be similar.

I copied a pand file (and the libbluetoothd.so) from a cyanogenmod image. it didn't help.
doing a logcat |grep bluetooth i noticed the following:
whenever i try to activate a mm connection from the phone to the car i get this line twice in the log file:
V/BluetoothEventManager(12390): Recieved android.bluetooth.a2dp.profile.action.CONNECTION_STATE_CHANGED
Since it's always twice, i think that it activates and immediately deactivates the a2dp connection to the car. looks like a programming error where you cant have 2 active bluetooth connections at the same time.
Hope they fix this really soon.

Not much help to you but I can get my UK S5 to connect fine to my factory car kit. I can connect for hands free, mp3 playback and as a modem for Internet all at once.

You were able to share Internet via Bluetooth?

Yep. You have to enable tethering to get it to work with Command Online through.

Can you explain how in more detail?

Turn on the tethering option (search tethering in settings). Your car will connect to the phone for online access. This is how the 2013 model works.

I have the same problem with my S5 Duos. My Car is a Skoda Yeti. My Android Version is 5.0 Lollipop.
I also spent a couple of hours. Has anyone solved the problem.
