nRF24L01 + PIC18LF26J50

Hiii to everyone

I am posting for the first time in this forum.

I am using nRF24L01. My problem is in the detection of the carrier in the Receiver side. I have followed some other suggestions from this forum. But, alas, I am not able to detect the carrier in the Receiver.

Can it be a Hardware problem?

Is it necessary to check the IRQ pin during data transmission and reception at the transmitter and receiver, respectively???

Please suggest.

Your precious time and help is appreciated…
