Bluetooth nonfunctional

[Benjamin]

When mine starts to play stupid, I find that it sometimes helps to 1.
forget the pairing 2. reset the pc 3. pair with the petrel and then to try
and download again. Sometimes it almost seems that the bluetooth on the pc
side is the bit which is causing the problems.

Just my 2 cents.
