I recently got an Arduino Bluetooth, but i have some difficulties setting it up.
In the Bluetooth Devices settings in Winxp i can see the ARDUINOBT and it has 2 COM ports. It says COM2 is an incoming connection and COM4 is an outgoing connection. In the Arduino program i can see COM2 but i cannot upload a sketch to it. I get a "com2 does not exist or your board is not connected" error. This kinda makes sens because its an incoming connection, but the thing is that COM4 only appears in the tools menu if i first reset the Arduino. Then it works, i can upload programs to the arduino and i can also get some values back if i look at the serial monitor (listening to COM4). I also use a C# .NET application to read from the serial ports, but its the same thing here, i first have to press the reset button on the arduino to be able to open the serial port in the program. Else i just get a time-out error.
It's really inconvenient to have to reset it before i can make a connection, so i hope someone has an idea about what i could be. Could it perhaps be the Bluetooth adapter i use? I am now using a really standard (nameless) bluetooth adapter ...
And does anyone know what's the deal with the 2 different serial connections?
