There should no delay in response after trying to connect. If an error, then the result to be messaged to the user. Appreciated, Rob Zitieren Link zu diesem Kommentar Share on other sites More sharing options...

With the connected IPConnection object create an object for the Bricklet and call its getIdentity method. If the method fails with a timeout then the Bricklet is not connected. The default timeout is 2.5 seconds. If that's too long you can make it shorter. How short it can be and still work reliable depends on the TCP/IP connection speed. You'll have to experiment.
