nRF24L01+ Product Specification

7.6

MultiCeiver™

MultiCeiver™ is a feature used in RX mode that contains a set of six parallel data pipes with unique add-

resses. A data pipe is a logical channel in the physical RF channel. Each data pipe has its own physical

address (data pipe address) decoding in the nRF24L01+.

Figure 12. PRX using MultiCeiver™

nRF24L01+ configured as PRX (primary receiver) can receive data addressed to six different data pipes in

one frequency channel as shown in Figure 12. Each data pipe has its own unique address and can be con-

figured for individual behavior.

Up to six nRF24L01+s configured as PTX can communicate with one nRF24L01+ configured as a PRX. All

data pipe addresses are searched for simultaneously. Only one data pipe can receive a packet at a time.

All data pipes can perform Enhanced ShockBurst™ functionality.

The following settings are common to all data pipes:

•

CRC enabled/disabled (CRC always enabled when Enhanced ShockBurst™ is enabled)

•

CRC encoding scheme

•

RX address width

•

Frequency channel

•

Air data rate

•LNA gain

The data pipes are enabled with the bits in the EN_RXADDR register. By default only data pipe 0 and 1 are

enabled. Each data pipe address is configured in the RX_ADDR_PX registers.

Note: Always ensure that none of the data pipes have the same address.
