Thanks for the reply!
Seems (curiously) similar in T2...I think? I have a few different
send/receive going on now. My question about accessing AMSenderC.Packet
(which is likely a T2 thing that I've picked up from one of the
example/tutorial programs) still remains though:
I've used the same AMSenderC for both my SenderN.send interfaces when
forming the Packet and it seems to work. Is there a higher level in T2 from
which to access the packet interface that I //should// use instead? :-)
components new AMSenderC(TYPE_ONE) as Sender1;
components new AMSenderC(TYPE_TWO) as Sender2;
...
App.Sender1 -> Sender1;
App.Sender2 -> Sender2;
...
App.Packet -> Sender1;
...
(and)
...
(inside Sender1.send func)
packet1 = (Packet1struct*)(call Packet.getPayload(&pkt, NULL));
...
(inside Sender2.send func)
packet2 = (Packet2struct*)(call Packet.getPayload(&pkt, NULL)); <--call
to [Sender1.]Packet??
Cheers,
Ben
