proptietary RF

I use the following settings to communicate with the nRF24L. But there is no connection. What's wrong?

 NRF_RADIO->TXPOWER = (RADIO_TXPOWER_TXPOWER_0dBm << RADIO_TXPOWER_TXPOWER_Pos); 
 NRF_RADIO->MODE = (RADIO_MODE_MODE_Nrf_2Mbit << RADIO_MODE_MODE_Pos);  
 NRF_RADIO->FREQUENCY = 2U;
 NRF_RADIO->BASE0 = 0xE7E7E7E7;
 NRF_RADIO->PREFIX0 = 0xE7;
 NRF_RADIO->TXADDRESS = 0;  
 NRF_RADIO->PCNF0 = (6UL << LFLEN) | (0UL << S0LEN) | (3U << S1LEN);
 NRF_RADIO->PCNF1 = (32UL << MAXLEN) | (4UL << BALEN) | (1UL << ENDIAN); 
 NRF_RADIO->CRCCNF = (2UL << 0);
 NRF_RADIO->CRCINIT = 0xFFFFUL; 
 NRF_RADIO->CRCPOLY = 0x11021UL; 
 NRF_RADIO->TIFS = 250UL;
 NRF_RADIO->PACKETPTR = (uint32_t)payload;

Hello,

Why not use the ESB library in SDKv15.2:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/esb_users_guide.html?cp=4_0_0_5_1_2#esb_backwards 

Examples:

Best regards,

Hi!

I would like to do this through registers for a deep understanding.

Best regards,

The source is available in the projects, for instance let the library setup the radio in the mode you are interested in, and then readout all the radio peripheral registers to check the actual configuration.
