  • 1.  Maintaining a TCP connection to a device

    Posted 08-12-2025 03:50

    Is it possible to maintain a tcp connection with a device?  I have a device that allows subscriptions to certain notifications, but I have found no way to keep the connection open. Dashboard closes the connection after each command sent.  Am I missing a trick?

    I think I have found a post with the solution:

    Hi Richard

    It depends on exactly how persistent you need the connection to be.  rosstalk.sendMessageWithResponse will hold the connection open long enough to read a single response from the server but will still ultimately close it.  If you truly need a persistent connection, this is done via the <listener/> tag where you can tell it to connect as a client - this will open a TCP/IP connection that will stay open for the entire life of your panel (and can also be closed/opened as needed by ogScript).
