About the interrupt of L01+

Alice

Hi

I have a question when I use the l01+.

I donn't use the Auto acknowledgement and Auto Retransmission, interrupt does not reflects on the IRQ pin and leave the IRQ pin unconnected,that is to say,the IRQ pin does not connect to MCU.I found that RF communication is failed when I do as the configuration.Must the IRQ pin connect to MCU and interrupt reflect on the IRQ pin?

Look forward to your reply. Thank you very much.

King regards, Alice

    No, it doesn't have to be connected. So you write 0xFE to the CONFIG if the PTX and 0xFF to the CONFIG of PRX as well, right?

    If that's the only thing you're doing you're also missing writing to the RX_PW_P0 register on the PRX the size of the payload it will be expecting, as the default is 0.

    Also don't forget to set the CE pin to 1 to be in active mode in both PRX and PTX.
