Re: Possible pauses with xPLHAL

[Tom Van den Panhuyzen <tomvdp@xxxxxxxxx>]

The hub is only needed to distribute xpl messages on a pc to the different
xpl apps. A device sends a msg (e.g. a hbeat.basic) to the hub. The hub
then
distributes this message to all its client xpl applications.
The device should listen on port 3865 for broadcasted UDP packages and
handle those - it does not depend on a hub.
Cheers
Tom
