I also have the Tinyos bluetooth sheild.
I seem to be able to pair the bluetooth device with my laptop. It creates two ports com4 and com5. I've tried sending text to it via putty. I can see some activity on one of the LEDs on the shield, but neither the rx or tx LEDs on the arduino get activated and my sketch does not receive the text.
I have the switch set to UART (pins 0 and 1) not pins 2+3.
I don't need to use the AT command to change the baud, because it defaults to 9600 buad for normal use. I thought i'd try it anyway, but that also does not work. It seems like the bluetooth bee is not communicating with the Arduino.
Does anyone have one of these working?
