https://devzone.nordicsemi.com/f/nordic-q-a/4736/nrf24l01-can-t-read-data-from-other-pipesHi, Master device is whole the time in receive mode and I have a problem with read data from device which address is in Pipe1. IRQ appear and status is 0x4e and FIFO status is 0x11. When I switch addresses between Pipe0 and Pipe1 everything is workingen-USTelligent Community 13Fri, 12 Dec 2014 08:52:53 GMThttps://devzone.nordicsemi.com/thread/16767?ContentTypeID=1Fri, 12 Dec 2014 08:52:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4a8bf39b-fccc-43bd-a51d-f852a3ebdffdAsbj&#248;rn<p>I assume you are using ACK. ACK is sent back to the transmitter to the same address the original payload was received on. On the transmitter side it&#39;s important that pipe0 is configured with the same address as the package was sent with. ACKs are received on pipe0. So it seems like you may have a mismatch between your TX address and pipe0 address on your transmitter.</p><div style="clear:both;"></div>
