I got Bluetooth working on the previous version of Raspbian, but I’m upgrading.. so I need it working in this version as well.

Needed to install the required tools..

apt-get install bluez python-gobject python-dbus

Then scan for the bluetooth device (hcitool scan) and then pair with it (bluez-simple-agent.) The rfcomm bind command creates the device. When you’re done, you can use rfcomm release 0 to drop it.

Then, I installed minicom and was able to change the serial port to /dev/rfcomm0 and set the baud rate. From there, I could take with the Arduino on the other end.

Just a note - I found that powering my Pi from a USB port on a computer, the bluetooth woudl fail. When powered from a stand alone USB battery (rated for 1amp) it worked.

This might come in handy.. seems to to the same as minicom when you start it..
