Reveal incoming BT port on WM5/WM6 devices
This tipp is from one of my fellows and it seems to be hard to find any resources on this.
If you need an incoming Bluetooth port on your WM5/6 device and you only got the option for outgoing ports, this tipp might help you.
It is a simple registry hack and needs a warmboot after change:
REGEDIT4 [HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Serial\Ports\Incoming] "Port"="COM0" "Server"=dword:00000001 "Authentication"=dword:00000001 "Encryption"=dword:00000001 "RemoteDCB"=dword:00000000 "KeepDCD"=dword:00000000
