nRF24L01 Product Specification
7.7 Multiceiver
Multiceiver is a feature used in RX mode that contains a set of 6 parallel data pipes with unique addresses.
A data pipe is a logical channel in the physical RF channel. Each data pipe has its own physical address
decoding in the nRF24L01.
Figure 10. 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 10.
Each data pipe has its own unique address and can be con-
figured for individual behavior.
Up to six nRF24L01s configured as PTX can communicate with one nRF24L01 configured as 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.
