I've been trying to test a bluetooth transceiver(BT0417C) I bought, and I have a few problems. First of all, my computer (with a bluetooth adapter) uses two COM ports to communicate with the transceiver, one each for input and output, understandably. But for some reason, the output COM port, the one that transmits to the transceiver, is missing. When I open up the properties for the transceiver in my computer, I see that it uses COM6; however, arduino and processing only detect COM7(recieving port). I've been using the code from Arduino playground (http://arduino.cc/playground/Learning/Tutorial01
) to test it out, and I'm pretty sure there are no hardware problems that would affect it (I have a deuemilanove, in case that helps). When I was running the processing code (back when I had two COM ports for the transciever) I configured it to use the COM port that transmits to the module, naturally, but I kept getting an error message. (I don't have access/can't find the port anymore, and I forgot to copy the error codes, so I don't have it, sadly.)
Also, some questions. I've connected the bluetooth rx and tx pins to arduino rx and tx, respectively. Do I need to declare the pins as output/input or is there some native protocol that allows the bluetooth module to access the serial already? Do I always need to use rx and tx for signal transmission? Or are any of the digital pins applicable?
Well, that's basically it. Sorry, kinda new to this, lol.
