How Can I Catch Error "serial port /dev/rfcomm0 closed unexpectedly"

[marcpouliot]

The error has a red vertical bar attached to it and does not refer to a node.
When the temporary bluetooth device is disconnected, the error occurs and repeats itself every 14-20 seconds. Once this error occurs, the status node changes from connected to not connected although it is not connected.
If I could catch this error message in a flow, I could then release the device. This would have the effect of stopping the invalid toggling of the status by giving only one error message (file not found).
I hope this is a bit clearer.
