nRF24L01 Product Specification
Appendix B - Configuration for compatibility with nRF24XX
How to setup nRF24L01 to receive from an nRF2401/nRF2402/nRF24E1/nRF24E2:
1. Use the same CRC configuration as the nRF2401/nRF2402/nRF24E1/nRF24E2
2. Set the PWR_UP and PRIM_RX bit to 1
3. Disable auto acknowledgement on the data pipe that is addressed
4. Use the same address width as the PTX device
5. Use the same frequency channel as the PTX device
6. Select data rate 1Mbps on both nRF24L01 and nRF2401/nRF2402/nRF24E1/nRF24E2
7. Set correct payload width on the data pipe that is addressed
8. Set CE high
How to setup nRF24L01 to transmit to an nRF2401/nRF24E1:
1. Use the same CRC configuration as the nRF2401/nRF2402/nRF24E1/nRF24E2
2. Set the PRIM_RX bit to 0
3. Set the Auto Retransmit Count to 0 to disable the auto retransmit functionality
4. Use the same address width as the nRF2401/nRF2402/nRF24E1/nRF24E2 uses
5. Use the same frequency channel as the nRF2401/nRF2402/nRF24E1/nRF24E2 uses
6. Select data rate 1Mbps on both nRF24L01 and nRF2401/nRF2402/nRF24E1/nRF24E2
7. Set PWR_UP high
8. Clock in a payload that has the same length as the nRF2401/nRF2402/nRF24E1/nRF24E2 is
configured to receive
9. Pulse CE to transmit the packet
