Correct.

Correct.

The way the PRX transmits data it to attach it to the ACK packet.

Thanks for the reply.

I tried nrf_esb_start_rx() instead of nrf_esb_start_tx(), but the situation is still the same and the sending operation is not working.

Isn't the operation that the module of 'NRF_ESB_MODE_PRX' transmits with nrf_esb_start_rx(), which means that the module of 'NRF_ESB_MODE_PRX' attaches the contents of the FIFO at the timing when it returns an ACK?

If that is the case, then as I stated at the beginning, I am using NRF_ESB_MODE_PRX intentionally not to return ACK, and the method you suggest would be invalid.

If it becomes clear that the NRF_ESB_MODE_PRX module, which does not return ACKs, cannot transmit spontaneously, we would like to consider another method.
After all, it is impossible for a module of NRF_ESB_MODE_PRX that does not return ACK to transmit spontaneously?

Hi,

[quote user=""]Specifically, from the module of RF_ESB_MODE_PRX we perform the following.
nrf_esb_write_payload(&tx_payload);
nrf_esb_start_tx();[/quote]

For PRX, try to use nrf_esb_start_rx() instead of nrf_esb_start_tx().
