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 14. is an example of an address configuration for the PRX and PTX. On the PRX the 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.

Figure 14. Example of data pipe addressing in MultiCeiver™

Only when a data pipe receives a complete packet can other data pipes begin to receive data. When mul-

tiple PTXs are transmitting to a PRX, the ARD can be used to skew the auto retransmission so that they

only block each other once.
