RE: how to configurate transmitter/receiver radio?

I have not tried it myself but it should be fairly straight forward to merge this examples.

Thing to take into consideration while merging is the packet pointer for NRF_RADIO->PACKETPTR. you have to configure this register everytime you send and receive data, so its best to have

static uint32_t     tx_packet;              /**< Packet to transmit. */
static uint32_t     rx_packet;              /**< Packet to transmit. */

also change

void send_packet()
{
     // Set payload pointer
     NRF_RADIO->PACKETPTR = (uint32_t)&tx_packet;

    // send the packet:
    NRF_RADIO->EVENTS_READY = 0U;
    NRF_RADIO->TASKS_TXEN   = 1;

    while (NRF_RADIO->EVENTS_READY == 0U)
    {
        // wait
    }
    NRF_RADIO->EVENTS_END  = 0U;
    NRF_RADIO->TASKS_START = 1U;

    while (NRF_RADIO->EVENTS_END == 0U)
    {
        // wait
    }

    uint32_t err_code = bsp_indication_text_set(BSP_INDICATE_SENT_OK, "The packet was sent\n\r");
    APP_ERROR_CHECK(err_code);

    NRF_RADIO->EVENTS_DISABLED = 0U;
    // Disable radio
    NRF_RADIO->TASKS_DISABLE = 1U;

    while (NRF_RADIO->EVENTS_DISABLED == 0U)
    {
        // wait
    }

     // Set payload pointer  to receive
     NRF_RADIO->PACKETPTR = (uint32_t)&rx_packet;
}

The rest are minor porting challenges.
Note that if you are testing this changes you need another transceiver which has to do transmit and receive in reverse order than the DeviceUnderTest.
