https://devzone.nordicsemi.com/f/nordic-q-a/16500/nrf24l01-no-ackI&#39;m using nRF24L01 in a star network and i want to disable ACK. I write the ACTIVATE command followed by 0x73, then a write to register FEATURE the value 0x01. In this way EN_DYN_ACK should be set. Then I transmit payload with the command W_TX_PAYLOAD_NOen-USTelligent Community 13Wed, 21 Sep 2016 08:33:16 GMThttps://devzone.nordicsemi.com/thread/63145?ContentTypeID=1Wed, 21 Sep 2016 08:33:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:58a0e76f-9a71-469e-80c0-4250d6a986efHung Bui<p>Hi Enzo,</p> <p>As you can see at Figure 10. PTX operations in Enhanced ShockBurst in the nRF24L01P specification, even with No_ACK set to true, the TX_DS still be triggered. It&#39;s triggered immediately the packet is sent.</p><div style="clear:both;"></div>
