Figure 7: Addressing data pipes 0-5

When a packet has been received at one of the data pipes and the data pipe is setup to

generate acknowledgement, nRF24L01 will generate an acknowledgement with an

address that equals the data pipe address where the packet was received.

Some configuration settings are common to all data pipes and some are individual.

The following settings are common to all data pipes:

• CRC enabled/disabled (CRC always enabled when ESB is enabled)

• CRC encoding scheme

• RX address width

• Frequency channel

• RF data rate

• LNA gain

• RF output power
