How to set DW1000 to rxenable all the time? We notice that it must set the RXENAB bit each time to receive

We notice that it must set the RXENAB bit to receive, each time.
So, we want to know whether there is a method to set DW1000 to rxenable all the time? No need to set RXENAB bit before received.

You can set the RXAUTR bit in the system control register. That will automatically re-enable Rx in certain situations.
But in general setting one bit at the end of your interrupt handler isn’t an excessive requirement and shouldn’t cause you any complications.
