Using maniacbug&#39;s RF24 library. Using pipes 0 and 1. When I set Auto-ACK ON for all pipes rf24.setAutoAck(true) : it works. When I set Auto-ACK OFF for all pipes rf24.setAutoAck(false) : it works too. en-USTelligent Community 13Thu, 18 Sep 2014 15:02:55 GMThttps://devzone.nordicsemi.com/thread/13247?ContentTypeID=1Thu, 18 Sep 2014 15:02:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f020e23-2a5a-4014-8eef-6792afde142aAsbj&#248;rn<p>Have you tried just opening one pipe and switching AutoACK on/off? Does it still work for just one pipe? Do you get any kind of interrupts when you have configured only one pipe with autoACK and the other without? Have you tried keeping the autoack on and using W_TX_PAYLOAD_NO_ACK write command?</p><div style="clear:both;"></div>
