Windows Phone 7 Bluetooth handsfree problem

I have a Samsung Focus. When using handsfree in my 2009 Mazda6, the bluetooth connection frequently drops. I can pair the devices very quickly and easily. I can play music over the car speakers perfectly. The BT connection drops during phone calls. I have icons on my dash that show when phone and music are connected to BT. I see the BT phone connection drop frequently. After some time, it will come back. However, when this condition occurs, if I go into settings -> bluetooth, the connection comes back immediately. I have tested this many times. It's almost like opening that bluetooth window forces it to connect again. This happens so frequently and is so embarrassing when I'm on calls, it is unusable. Also, even when it is connected, the sound quality is horrible. The music, however, sounds fantastic. Anyone else having this issue? Any thoughts?

I'm using a HTC Trophy 7 in combination with a Volvo V70.

Can you check whether the phone is rebooting at the time of the break of connection?

Mine sometimes reboots, reconnects to the car but on the phone itself it's waiting for the pin to continue and thus I'm unreachable until I enter the pin.

Hi Dieter,

No, I am not having the same issue. The phone is not rebooting. The phone is fully functional while this is happening. In fact, what I have to do is switch to speaker so I can continue the conversation. Also, like I said, if I go into the bluetooth applet, it immediately reconnects.

I'm having a bluetooth problem with my hands-free as well.  I'm using a Pioneer Premier FH-P800BT receiver, which uses the HFP, A2DP, and AVRCP bluetooth profiles.  Audio streams to the receiver without problems, but when a phone call is received, the audio is routed through the phone's speaker rather than through the receiver, even though the receiver notices that a phone call is incoming (even displays the contact name).

@goyasin, are you sure bluetooth is dropping, or is the sound coming through the phone's speaker like it does for me?

Woops, I missed the part where you mention that you actually get sound through your bluetooth connection, until it drops.  Different problem, I suppose.  Mine maintains the bluetooth connection, but doesn't route the audio through the preferred device.

Have a brand new Volvo V70 with their Bluetooth kit.

When connecting my phone (HTC Mozart) the phone will randomly restart when connecting or soon after connection when I use the phone for almost anything.

Anyone experienced anything like that? It's like a BSD on the phone ;-)

I have a Samsung Focus running Win 7, and a '07 Mini Cooper S.  My focus also syncs up just fine with the car, but calls are difficult to hear due to poor sound qaulity.  It "works", but very staticky.

All functions work but when I sync the phonebook the phone just reboots.

 

Well, you're one step closer to a resolution than I am.  I have a Pioneer Premier FH-P800BT head unit installed in my truck, and it does detect incoming calls (and displays the associated contact), but doesn't output the audio through bluetooth to my receiver.  Instead, the audio is piped through the earpiece of my phone (Samsung Focus).
