@Chaw: Have you checked out the product spec of the nRF24LU1 ? You can find the the EN_RXADDR register at page 57 (section 6.6). If you want to enable a pipe you set the according bit in the register. By default pipe 1 and pipe 0 is enabled. You can disable them by set the bit to 0.

You can also have a look inside the source code of the hal_nrf_open_pipe() to see how it works. It's in hal_nrf.c

yes, I means PRX, I want to know:

if I only use default settings in PRX without hal_nrf_open_pipe, which pipes will be listening? all pipes?
if I use hal_nrf_open_pipe to enable someone pipe, like pipe 5, nRF24 can only listen pipe 5? Plz help me . Thanks.

There is only one pipe for TX transmitting, this stated in the nRF24LU1+ spec: "On the PTX the TX_ADDR must be the same as the RX_ADDR_P0 and as the pipe address for the designated pipe"

If you are talking about PRX, you call hal_nrf_open_pipe() for each of the pipe you want to open.
