nrf52840 esb send and receive bidirectional with nrf24l01 on other end

Hello

I'm using an nrf52840 (PCA10059) together with an nrf24l01 (ESP32, MIRF Library).

My goal is to send a data packet from the nrf52840 which the nrf24l01 can receive, The nrf24l01 should then send a data packet back to the nrf52840.

This seems to be pretty straight forward in the MIRF Library:

	while(1) {
		//When the program is received, the received data is output from the serial port
		if (Nrf24_dataReady(&dev)) {
			Nrf24_getData(&dev, mydata.value);
			ESP_LOGI(pcTaskGetTaskName(0), "Got data:%lu", mydata.now_time);
			
			vTaskDelay(1);
			Nrf24_send(&dev, mydata.value);
			vTaskDelay(1);
			ESP_LOGI(pcTaskGetTaskName(0), "Wait for sending.....");
			if (Nrf24_isSend(&dev)) {
				ESP_LOGI(pcTaskGetTaskName(0),"Send success:%lu", mydata.now_time);
			} else {
				ESP_LOGW(pcTaskGetTaskName(0),"Send fail:");
			}
		}
		vTaskDelay(1);
	}

But I'm not sure how to implement this on the nrf52840. This is my current implementation. How can I send back in this implementation? I'm confused as there is just NRF_ESB_MODE_PTX and NRF_ESB_MODE_PRX but not both:

uint32_t esb_init(void)
{
    nrf_gpio_cfg_output(6);
    nrf_gpio_pin_set(6);

    uint32_t err_code;
    uint8_t base_addr_0[4] = {0xE7, 0xE7, 0xE7, 0xE7};
    uint8_t base_addr_1[4] = {0xC2, 0xC2, 0xC2, 0xC2};
    uint8_t addr_prefix[8] = {0xE7, 0xC2, 0xC3, 0xC4, 0xC5, 0xC6, 0xC7, 0xC8};

    nrf_esb_config_t nrf_esb_config = NRF_ESB_LEGACY_CONFIG;

    nrf_esb_config.retransmit_count = 6;
    nrf_esb_config.selective_auto_ack = false;
    nrf_esb_config.protocol = NRF_ESB_PROTOCOL_ESB;
    nrf_esb_config.bitrate = NRF_ESB_BITRATE_2MBPS;
    nrf_esb_config.event_handler = nrf_esb_event_handler;
    nrf_esb_config.mode = NRF_ESB_MODE_PTX;
    nrf_esb_config.payload_length = 4;

    err_code = nrf_esb_init(&nrf_esb_config);
    VERIFY_SUCCESS(err_code);

    err_code = nrf_esb_set_base_address_0(base_addr_0);
    VERIFY_SUCCESS(err_code);

    err_code = nrf_esb_set_base_address_1(base_addr_1);
    VERIFY_SUCCESS(err_code);

    err_code = nrf_esb_set_prefixes(addr_prefix, 8);
    VERIFY_SUCCESS(err_code);

    nrf_esb_set_rf_channel(90);

    tx_payload.length = 4;
    tx_payload.pipe = 0;

    tx_payload.data[0] = 0;
    tx_payload.data[1] = 0;
    tx_payload.data[2] = 0;
    tx_payload.data[3] = 0;

    nrf_gpio_pin_clear(6);

    return NRF_SUCCESS;
}

int main(void)
{
    esb_init();

    while (1)
    {
        tx_payload.noack = false;
        nrf_esb_write_payload(&tx_payload);
        
        nrf_delay_ms(10);
    }
}
