Hi again,
Having gotten serial communication working, I now have a problem with
execution of a command being deferred. As a small example for this email, I
have the following code:
event TOS_MsgPtr msgIn.receive(TOS_MsgPtr m) {
struct testSendMsg *r;
TOS_MsgPtr tmp;
tmp = pBuffer;
pBuffer = m;
r = (struct testSendMsg*)tmp->data;
cmd = r->cmd;
if (cmd == 1)
call Leds.redToggle();
return tmp;
}
'cmd' is part of the message data field, and is set by the Delphi program
sending the message to a mote. Hence, on sending a message, the red led
should toggle. However, it doesn't the first time a packet is sent; instead
it waits until the second packet. Why would this be?
I have checked that the packet is being sent by analysing serial traffic -
also, if I remove the condition statement then the red led does toggle, so I
am a little confused...
Cheers,
