https://devzone.nordicsemi.com/f/nordic-q-a/17083/ack-on-pipe-1-no-ack-on-pipe-0I have a star network that works faithfully in no ACK way, using only pipe0. Now i want to use pipe 1 to transmit from one nRF24L01+ to the star center, with ACK this time (to increase relibility). EN_RXADDR is set to 0x1 when i use pipe1; ARD=750usec;en-USTelligent Community 13Mon, 17 Oct 2016 12:16:40 GMThttps://devzone.nordicsemi.com/thread/65510?ContentTypeID=1Mon, 17 Oct 2016 12:16:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0cee7cc1-6716-4356-aeea-ae28d800f5ebovrebekk<p>Good to hear you found the issue :)<br /> Pipe 0 is always used to receive the ACK on the PTX side, which is why pipe 0 needs to be enabled in EN_RXADDR on the PTX even if you are transmitting to pipe 1 on the PRX.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65509?ContentTypeID=1Mon, 17 Oct 2016 11:25:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a11448eb-e841-4252-99ae-f02b855d0e6benzo<p>I have found the error. When I use pipe1 i must set EN_RXADDR=0x3. In fact even pipe0 must be enabled.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65508?ContentTypeID=1Mon, 17 Oct 2016 09:05:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:45bab237-db86-43b3-ace5-1fb6815a6f58ovrebekk<p>If you want to use both pipe 0 and pipe 1 you should set EN_RXADDR to 0x03. Can you confirm this?</p><div style="clear:both;"></div>
