nRF24L01 Product Specification
The PRX, using multiceiver and Enhanced ShockBurst™, receives packets from more than one PTX. To
ensure that the ACK packet from the PRX is transmitted to the correct PTX, the PRX takes the data pipe
address where it received the packet and uses it as the TX address when transmitting the ACK packet.
Figure 12.
RX_ADDR_Pn, defined as the pipe address, must be unique. On the PTX the TX_ADDR must be the same
as the RX_ADDR_P0 and as the pipe address for the designated pipe.
No other data pipe can receive data until a complete packet is received by a data pipe that has detected its
address. When multiple PTXs are transmitting to a PRX, the ARD can be used to skew the auto retrans-
mission so that they only block each other once.
Revision 2.0
is an example of how address configuration could be for the PRX and PTX. On the PRX the
