Add Hoc communication between NRF24L01+ devices

[orbitcoms]

I notice in the datasheet for the NRF24L01+ that the receive address needs to be programmed into the Receiver.

Our application receives data from another channel and supplies the address of the destination of the current packet. However, the unit receiving this packet cannot determine which device sent the packet until it has been received, we cannot program the receiver in advance.

Does this mean the receiver cannot receive add-hoc packets from unknown transmitters, or does it mean they can receive and deliver the payload but cannot send back the ack? (We were looking at using enhanced Shock Burst)

You have to know the address that the transmitter will send on. There's no promiscuous mode that enable you to read out bit by bit on the nRF24L01+. So if you program all the transmitter to initially use one know address, you can use this to set up the connection and then generate a random address to use from there on out.

As long as it's just one pair with the same addresses available at the same time, then yes, the scenario you describe would work.
