I am trying to talk from my iPAQ 5450 to another Bluetooth-enabled device programmatically, using VB.NET. I have a program which works fine between my PDA and my PC, using the serial port (COM 1). I have modified the program to use ports 5 and 8, which the BLuetooth Manager says are the ports for serial comms in Bluetooth. When I open the outbound port on 1 iPAQ, it correctly discovers the other one, which asks me to authorise the connection, and vice versa when I run the prog on the 2nd iPAQ - but that's it! I can't seem to send or receive anything. The program works fine with my iPAQ and PC via a serial link.
Can anyone help, please?
