NRF52833 RADIO intelligent configuration realizes CTE broadcast transmission

[XSJ]

Hi !

    I want to successfully send CTE after the CRC of the broadcast packet by operating the RADIO register under the Manual configuration of NRF52833。At present, I can successfully send identifiable broadcast packets, but after adding the DFE-related register configuration, the receiver does not get the correct sampling data, which means that the CTE is not generated after the CRC. Is there any other EVENT that is not enabled correctly, causing the CTE transmission to not be triggered? Or is it another problem? Some codes are as follows:

    
    NRF_RADIO->SHORTS = (RADIO_SHORTS_READY_START_Enabled << RADIO_SHORTS_READY_START_Pos) |
                        (RADIO_SHORTS_END_DISABLE_Enabled << RADIO_SHORTS_END_DISABLE_Pos) |
                        (RADIO_SHORTS_ADDRESS_RSSISTART_Enabled << RADIO_SHORTS_ADDRESS_RSSISTART_Pos) |
                        (RADIO_SHORTS_DISABLED_RSSISTOP_Enabled << RADIO_SHORTS_DISABLED_RSSISTOP_Pos);
                        
    NRF_RADIO->INTENSET = (RADIO_INTENSET_END_Enabled <<  RADIO_INTENSET_END_Pos) |
                          (RADIO_INTENSET_RSSIEND_Enabled << RADIO_INTENSET_RSSIEND_Pos);
    NVIC_SetPriority(RADIO_IRQn, 1);
    NVIC_ClearPendingIRQ(RADIO_IRQn);
    NVIC_EnableIRQ(RADIO_IRQn);

Best Regards！

Hi

Have you checked out our Direction Finding whitepaper which shows you how to set up transmitter and receiver in the nRF52833. 

Best regards,
