you need to setup up to 6 devices on the same network (same high bytes on address) all as PRX, when any device want to send data, just set the TXaddress to the device you want to send, load the tx payload and change to PTX, once it finished to send data, change to PRX...
remember you can't use Enhanced Shockburst because you don't know which device will send data to you, so you need to implement your own handshake and retransmit protocols..
for basic nRF code, look for kehribar's code, it worked for me, but for your exact application, sorry no code...
