The actual error is missing. :-( A look at the code reveals that there are two 
Bluetooth connect errors which aren't being logged. This, although I don't 
remember at the moment, is presumably because they can be very common and would 
just clutter up a user's regular log. I've now added to the code that these 
errors should also be logged if the log level is debug. Please update and give 
it another try.

One thing I notice from the two logs quoted above is that, right down to the 
millisecond, the timestamps are teh same. This implies that the error, whatever 
it is, is immediate. Since Bluetooth operations involving the device wouldn't 
likely be that fast, I'm suspecting that the erorr is occurring within the host 
before it even attempts to contact the device. The most probable cause for this 
would be that the Bluetooth service on the host isn't running (which, 
interestingly, is one of the errors which wasn't being logged).
