1)So the correct configuration for this example is:
FRED: PAN ID:3128, MY=8001, DL=4382
SUE: PAN ID: 3128, MY=4382, DL= 8001?
And a little more on that since in the future I would like to expand it with ore:
I have FRED, SUE, NICK. I want Fred to send to everyone, and Sue and Nick to send back only to Fred.
2) I read somewhere that if you want the sending data to be received from all the XBee's with the same PAN ID, then DL and MY must be set to 0. So I left them to 0, and then whatever I send from from Fred can be read from every XBee, and whatever I send from Sue is not read by anyone? So what I did is something like:
send("s"); or send("n");
if read=="s" then code for sue
else if read="n" code for nick.
And in the code for sue I have send("result"). But this is not send.
What configuration do I need?
