Basically I have an Xbee connected to my computer and I want it to be able to talk to 3 xbee radios. I understand it requires AT commands to configure it.
what are the specific changes that I need to make for each Xbee radios?
set each xbee with the same ID address
Provide destination address same on all the modules.
That is dependent upon which XBee modules you are referring to. In most cases, it is nothing more than setting the DL and DH of the transmitting module to the SL and SH of the receiving module.
Example:
+++
ok
ATDL0013A200
ok
ATDH48314635
ok
ATCN
