Configuration for compatibility with nRF24XX
How to setup nRF24L01 to receive from an nRF2401/nRF2402/nRF24E1/nRF24E2:
 Use same CRC configuration as the nRF2401/nRF2402/nRF24E1/nRF24E2
uses

Set the PRIM_RX bit to 1
 Disable auto acknowledgement on the data pipe that will be addressed

Use the same address width as the PTX device
 Use the same frequency channel as the PTX device

Select data rate 1Mbit/s on both nRF24L01 and
nRF2401/nRF2402/nRF24E1/nRF24E2
 Set correct payload width on the data pipe that will be addressed
 Set PWR_UP and CE high
How to setup nRF24L01 to transmit to an nRF2401/nRF24E1:

Use same CRC configuration as the nRF2401/nRF2402/nRF24E1/nRF24E2
uses

Set the PRIM_RX bit to 0
 Set the Auto Retransmit Count to 0 to disable the auto retransmit functionality
 Use the same address width as the nRF2401/nRF2402/nRF24E1/nRF24E2
uses

Use the same frequency channel as the
nRF2401/nRF2402/nRF24E1/nRF24E2 uses
 Select data rate 1Mbit/s on both nRF24L01 and
nRF2401/nRF2402/nRF24E1/nRF24E2

Set PWR_UP high
