Re: Communicatiing with xplHal

[Mal Lansell <mlansell@xxxxxxxxxxxxxx>]

Actually I sorted it last night - hooray :-)

I just had to bind the receiving socket to ADDR_ANY rather than the
local IP - I'm guessing this is something to do with the hub
broadcasting messages rather than sending them to my specific address?

Anyway, all the config communication is now working.  There was just one
received message that I wasn't expecting - my own config.app heartbeat!
I suppose since the target is * that makes sense...

I was thinking of storing the device config in the registry - is there
any good reason not to do this?  Is there a defined structure for
placing keys under HKEY_LOCAL_MACHINE/SOFTWARE/xPl?  By Vendor/Device
perhaps?

And finally - I mentioned needing a vendor ID, and suggested MAL -
anyone know if this is OK?
