Daly error 147 - Bluetooth seems to work, but then fails

[wimg]

The Daly device is detected over Bluetooth, but then Daly error 147 occurs.

Any idea what might be wrong ? I've tried the various Bluetooth troubleshooting steps, but they seem to have no effect.

Paste log output between BEGIN and END:

The above exception was the direct cause of the following exception:
