Earlier this year I made a bluetooth controlled car using a bluetooth module and a small java app for my k750i to control the car with. (Details here.) The java app uses a serial port profile to communicate with the BT module and works excellently on my k750i. When testing it with some other phones it wouldn't work however, and now that I've got myself a N85 I thought I would look at the problem again.
When searching for bluetooth services provided by my phone, using my PC, I noticed that the serial port profile wasn't in the list. This explains why the app doesn't work, but is there really no serial port profile in the N85, or other newer phone models for that matter?
