================ NRF Configuration ================

STATUS = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7

TX_FULL=0

RX_ADDR_P0-1 = 0xccccccccc3 0xcccccccc3c

RX_ADDR_P2-5 = 0x33 0xce 0x3e 0xe3

TX_ADDR = 0xe7e7e7e7e7

RX_PW_P0-6 = 0x20 0x20 0x20 0x20 0x20 0x20

EN_AA = 0x3e

EN_RXADDR = 0x3f

RF_CH = 0x5a

RF_SETUP = 0x07

CONFIG = 0x0f

DYNPD/FEATURE = 0x3f 0x04

Data Rate = 1MBPS

Model = nRF24L01+

CRC Length = 16 bits

PA Power = PA_MAX

Notice the output contains statistics from the RF24 module as it is

starting up. It contains valid values for the RX, an address (that is,

non-zero values) as well as the rest of the NRF configuration. If the

RF24 and RF24Network modules were not installed properly, or if

the Raspberry Pi could not communicate with the nRF24 module

via SPI, you would either get an error message from the example

program (it would not start at all), or the configuration values would

be blank. Now the RF24 modules are installed, the Python script

you installed will be able to work.
