nRF24L01 no Ack

[enzo]

I'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_NO ACK.

I expect to receive no ACK, but interrupt says that a packet as been transmitted. Why this? The same firmware is on all nRF24L01 .

Hi Enzo,

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's triggered immediately the packet is sent.
