Description
Hi,
For beginning thank you for this node module :).
I have an electron program that open a bluetooth connection and listening the event "data".
How can I know if the connection is always open ?
Before write data I check if the connection is open with connection.isOpen() but this method return true if the connection has been open and lost.
I have try to listen the events "closed", "close", "failure" without any success.
If the connection has been open and lost, when I write data I have an uncatched exception:
Error : Error reading from connection.
The calls to the write method is in try/catch block
Node version : v8.12.0
node-bluetooth: v1.2.5
Thank you for your help.

Research direction
No files or tests are named. Start by tracing connection.isOpen(), the connection-loss handling, and the write path in node-bluetooth, then reproduce the failure with the stated Node v8.12.0 and node-bluetooth v1.2.5 versions. Done means a lost connection can be detected reliably before writing and does not produce an uncaught error.
