I have paired my car (BMW 330) with my HTC Desire and it all was working well. Last night though, after putting the 'bluetooth file transfer' widget on my home screen and turning bluetooth and visibility on, the phone kept connecting to the car and after a short while was losing the connection. I am not sure if it was the widget causing the problem, but I removed it from my home screen, restarted the phone and went shopping. When I got back I noticed that the phone was connecting to the car and the two stayed happy with one another until I got home, some 45 minutes later. I also noticed that on the 'bluetooth file transfer' widget one button was for 'making the phone visible for 300 seconds' while if I go through settings the visibility time is 119 seconds. Could this have something to do with my problem? Has anyone had this sort of problem? Do you know if froyo will help with bluetooth connectivity issues?
