Logging stops

[mark-prins]

Fixes #212

The blue maestro sensors are not reporting connection status correctly:

• deviceIsConnected? { deviceIsConnected: true }
• try disconnecting [BleError: Device D7:D6:67:E0:02:34 is not connected]
• trying to connect: [BleError: Device ? is already connected]

to work around this - am now disconnecting blue maestro while catching and ignoring errors, then connecting.

Another issue is that the uuid generation is throwing an error uuid.v1(): Can\'t create more than 10M uuids/sec when being called within a map loop if there are a lot of logs. Am pausing for a millisecond if this happens to allow the uuid generation to continue.
