There is a huge amount of debate on the forums as to what Bluetooth profiles Windows Mobile devices support. Below is the list that we support natively in the Microsoft Stack in AKU 1.1 of Windows Mobile 5.0 and beyond:
Generic Access Profile (GAP)Generic Object Exchange Profile (GEOP)Serial Port Profile (SPP)Dial-up Networking (DUN) ProfileHands-Free Profile (HFP)Headset Profile (HSP)Human Interface Device (HID) ProfileObject Push Profile (OPP)ActiveSync-Over-BluetoothAdvanced Audio Distribution Profile (A2DP)Audio/Video Remote Control Profile (AVRCP)
The confusion typically starts because it is up to to the OEM to choose which ones they implement or to add additional support for other profiles.
