6.4.8 MultiCeiver™
MultiCeiver™ is a feature used in RX mode that contains a set of six 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 (data pipe address) decoding in the RF Transceiver.
The RF Transceiver configured as PRX (primary receiver) can receive data addressed to six different data
pipes in one frequency channel as shown in Figure 13. Each data pipe has its own unique address and can
be configured for individual behavior.
Up to six RF Transceivers configured as PTX can communicate with one RF Transceiver 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.
Note: Always ensure that none of the data pipes have the same address.
Each pipe can have up to a 5 byte configurable address. Data pipe 0 has a unique 5 byte address. Data
pipes 1-5 share the four most significant address bytes. The LSByte must be unique for all six pipes.
