NRF24L01+ Dynamic Payload communicate with 51822

[zcmm]

  Dear All：
       My NRF24L01+ use Dynamic PayLoad,What register need configure NRF51822?

NRF24L01+ Configuration as follow:

		SPI_RW_Reg(WRITE_REG + DYNPD, 0x01);//Enable the dynamic payload length of pipe 0

	SPI_RW_Reg(WRITE_REG + FEATURE, 0x04);//Enable the Dynamic Payload Length 

	SPI_RW_Reg(WRITE_REG + EN_AA, 0x00);//disable auto acknowledgement

how to configure NRF_RADIO->PCNF0 and NRF_RADIO->PCNF1?

i config as follow,but it can't recevice NRF24L01+ data

#define PACKET_S1_FIELD_SIZE (3UL) /< Packet S1 field size in bits. */ #define PACKET_S0_FIELD_SIZE (0UL) /< Packet S0 field size in bits. */ #define PACKET_LENGTH_FIELD_SIZE (6UL) /**< Packet length field size in bits. */

// Packet configuration
NRF_RADIO->PCNF0 = (PACKET_S1_FIELD_SIZE     << RADIO_PCNF0_S1LEN_Pos) |
                   (PACKET_S0_FIELD_SIZE     << RADIO_PCNF0_S0LEN_Pos) |
                   (PACKET_LENGTH_FIELD_SIZE << RADIO_PCNF0_LFLEN_Pos); //lint !e845 "The right argument to operator '|' is certain to be 0"

// Packet configuration
NRF_RADIO->PCNF1 = (RADIO_PCNF1_WHITEEN_Disabled << RADIO_PCNF1_WHITEEN_Pos) |
                   (RADIO_PCNF1_ENDIAN_Big       << RADIO_PCNF1_ENDIAN_Pos)  |
                   (PACKET_BASE_ADDRESS_LENGTH   << RADIO_PCNF1_BALEN_Pos);

Hi,

Have you looked in to this library? github.com/.../nrf51-micro-esb

This is a lightweight implementation of ESB on the nRF5x-devices (also supporting "NOACK" as you're using), which is by-design backwards compatible with nRF24L-series radios.

Just make sure that you are setting the same address and RF address on both sides, and communication should work.

Cheers, Håkon

Thanks.May be it is my wrong.51822 can receive 24L01P's data, The 51822 surrounding have 50 tags that with same channels、rate、 tx address and disable dynamic payload. only a device to enable the dynamic load, but this equipment is difficult to receive or the frequency of receiving（one tag that enable dynamic payload）is too little. the tag send data per 30 seconds, 51822 just received once in ten minutes , but with 24 l01p,it can receive all data(the tag send).Why?
