nRF24L01 activity

Hello,

I’m observing a strange behaviour of my nRF24L01+ chip

The PTX send packet every 2.5ms.

I can see with oscilloscop the CE and the IRQ pin.

I can observe the ACK is received by the PTX but I can’t see any activity on the PRX. IRQ and CE pin are every time in high state.

I read 0x0B in the config register of the PRX.

If I turn off the PRX there is no ACK on the PTX(to be sure of the source of the ACK).

Did you ever observe this behaviour ?
