i'm sorry if this is the wrong topic :/
I want to send the data of a potentio-meter and a button to another reciever with one transmitter, but i don't know how to read both of those sent data's on the reciever. Do I need different pipes for each assignment?
Can someone help me?
You can do everything with one pipe. Have a look at the examples in this Simple nRF24L01+ Tutorial (http://forum.arduino.cc/index.php?topic=421081)
If you just need one-way communication the first example should be suitable.
