If you need guaranteed, ordered delivery from one machine to another
then you should use TCP sockets instead of UDP sockets. Since you seem
to be sending directly between two machines this is ideal. In Pd it is
trivial to set up a TCP connection with [netsend] and [netreceive]. TCP
has slightly larger overhead than UDP because of the ACKs but I think
over WiFi you will not notice the difference.
One issue with using a TCP socket is negotiating the initial connection.
Pd requires you to enter the exact IP address which is a bit cumbersome,
especially during set up for live performance with Pd. UDP packets on
the other hand allow you to send in "broadcast" mode. If [netreceive]
allowed you to obtain the source IP address of incoming broadcast
packets then it would be possible to use that to negotiate a TCP
connection back to the source address after doing a "discovery"
broadcast & reply exchate - kind of like zeroconf/bonjour. I'll have a
think about a patch to submit to Miller for accomplishing this - should
be small and simple.
Cheers,
Chris.
