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
• Clock in a payload that has the same length as the
nRF2401/nRF2402/nRF24E1/nRF24E2 is configured to receive
• Pulse CE to send the packet
