https://devzone.nordicsemi.com/f/nordic-q-a/92578/nrf24l01Hi all, Is it possible to get an IRQ signal on receipt datas when the nRF24L01+ is in a SLEEP MODE ?en-USTelligent Community 13Thu, 06 Oct 2022 13:39:20 GMThttps://devzone.nordicsemi.com/thread/389649?ContentTypeID=1Thu, 06 Oct 2022 13:39:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a3b5089-7cbe-4318-bb15-af5befbcadd2ketiljo<p>Do you read the received packets? You need to clear the RX FIFO, else you won&#39;t get any more IRQs</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/389356?ContentTypeID=1Wed, 05 Oct 2022 09:34:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7dd8b467-3930-4545-89b4-2db759099735PF49<p>My goal was to reduce consumption and optimize CPU working time. I have an nRF24L01+ that sends one frame every second and another that receives it.&nbsp; I tried to sync them to IRQ. The receiver on IRQ, works and then goes into standby mode for 250 ms.&nbsp; Then I turn it back on but the receiver no longer wakes up (no more IRQ). Do I need to reconfigure the nRF24L01+ to work properly?&nbsp; (I&#39;ll try this today).&nbsp;</p> <p>I want to clarify that if I don&#39;t put the receiver in STANDBY mode, everything works fine...</p> <p>Thank you for your help.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/389322?ContentTypeID=1Wed, 05 Oct 2022 07:59:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6bb91a3e-7adc-4fbc-9983-ac9aa246cd91ketiljo<p>No. The RX must be on to receive anything.</p><div style="clear:both;"></div>
