Re: Re: W800

[Mal Lansell <mal@xxxxxxxxxxx>]

That doesn't happen with the latest version - the hub sends messages
directly to the port and ip listed in the heatbeat message.
However, you say that it should send to the loopback address, and that
apps should bind to the loopback address.  This is different from what
Tom has been saying, which is that they should bind to a real local IP
(might explain some of the problems with xPLHal's hub and V3 apps!)

Anyway, I'll try changing the code to use the loopback address, and see
what happens.

Thanks
