devices: close connection when throwing protocol exception on 'open' #149

Closed daescalona closed 4 years ago

daescalona commented 4 years ago

If there was a protocol missmatch when opening the XBee object connection, an exception was thrown but port remained open. This commit fixes this scenario and closes the connection before throwing the exception.
