Hey there,
I try to get the Arduino BT running again.
Bluetooth died on me.
I used to upload sketches from Windows, and it worked well ( for about a week or so)
Now, Bluetooth isn't "available" anymore.
The device gets recognized after pressing reset and disappears when the sketch starts.
The sketch was reading a parallax - reader and writing the output to serial.
So what could I possibly have done wrong?
How can I fix it?
LED connected to PIN13 blinks 3 times on reset,
3v3 LED is constantly on
Arduino BT is connected to an 4*1,2V Battery-Pack
Help! Please
