If you use an nRF24L01+ 2.4GHz transceiver to send a message all of the other nRF24s in range and listening on the same address will receive the message. You would need to turn off acknowledgments to prevent utter confusion.
I got my nRF24s working with this Tutorial
I suggest you use the TMRh20 version of the RF24 library - it solves some problems from the ManiacBug version
The pair of programs in this link may be useful.
...R PS. If this does not deal with your problem it is because you did not explain your requirement sufficiently.
