nRF24L01+

[PF49]

Hi all, Is it possible to get an IRQ signal on receipt datas when the nRF24L01+ is in a SLEEP MODE ?

No. The RX must be on to receive anything.

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.  I tried to sync them to IRQ. The receiver on IRQ, works and then goes into standby mode for 250 ms.  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?  (I'll try this today). 

I want to clarify that if I don't put the receiver in STANDBY mode, everything works fine...

Thank you for your help.

Do you read the received packets? You need to clear the RX FIFO, else you won't get any more IRQs
