https://devzone.nordicsemi.com/f/nordic-q-a/51843/gazell-reception-interrupt-for-nrf24lu1To the kind attention of Nordic support team, I have got legacy code to work with for nRF24LU1. Radio packets payload and receiving pipe are retrieved using if(gzll_rx_fifo_read(payload, &amp;length, &amp;receive_pipe)) instruction inside a super loop pollingen-USTelligent Community 13Fri, 06 Sep 2019 13:56:10 GMThttps://devzone.nordicsemi.com/thread/208490?ContentTypeID=1Fri, 06 Sep 2019 13:56:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:59835364-dedd-4e1d-9d4d-fb7c42a4c1f3astella<p>Thank you very much</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/208480?ContentTypeID=1Fri, 06 Sep 2019 13:36:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3eea39f7-9e15-4e4d-b930-2cdeb9f18908H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>Unfortunately, the nRF24L implementation of gazell is designed around polling. There&#39;s certain aspects in 8051 that can be challenging, such as function pointers, as there&#39;s several RAM types in 8051, and handling memory overlaying can then be challenging. See this app note for more info:</p> <p><a href="http://www.keil.com/appnotes/docs/apnt_129.asp">http://www.keil.com/appnotes/docs/apnt_129.asp</a></p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
