xbee receives but not send back data

PaulS:

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?

Yes. Or any values, as long as PAN ID is the same on both and MY on one is DL on the other.

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.

The FRED needs a MY value that SUE and NICK use as the DL value. SUE's and NICK's MY address doesn't matter. FRED's DL address will be 0xFFFF - the broadcast address.

I don't think that using 0 as MY or DL on any of the XBees is a good idea.

it does not seem to work. Do I set all of the three to be end-devices or FRED must be co-ordinator? Does it make any difference?
