I am new to Stackoverflow. I have searched for answer, but didn't find anything.

I have two Raspberry Pi 2B+, each with nRF24l01 connected. I found few libraries to make this connect, only one give any results, but not connections. This one: Github BLavery

I write script to send and to recv:

send.py:

import RPi.GPIO as GPIO
from lib_nrf24 import NRF24
import time
import spidev

GPIO.setmode(GPIO.BCM)

pipes = [[0xe7, 0xe7, 0xe7, 0xe7, 0xe7], [0xc2, 0xc2, 0xc2, 0xc2, 0xc2]]

radio = NRF24(GPIO, spidev.SpiDev())
radio.begin(0, 17)
radio.setPayloadSize(32)
radio.setChannel(0x60)

radio.setDataRate(NRF24.BR_2MBPS)
radio.setPALevel(NRF24.PA_MIN)
radio.setAutoAck(True)
radio.enableDynamicPayloads()
radio.enableAckPayload()

radio.openWritingPipe(pipes[1])
radio.printDetails()

while True:
 message = list("Hello World")
 radio.write(message)
 print("We sent the message of ".format(message))

 # Check if it returned a ackPL
 if radio.isAckPayloadAvailable():
 returnedPL = 
 radio.read(returnedPL, radio.getDynamicPayloadSize())
 print("Our returned payload was ".format(returnedPL))
 else:
 print("No payload received")
 time.sleep(1)

recv.py:

import RPi.GPIO as GPIO
from lib_nrf24 import NRF24
import time
import spidev

GPIO.setmode(GPIO.BCM)

pipes = [[0xe7, 0xe7, 0xe7, 0xe7, 0xe7], [0xc2, 0xc2, 0xc2, 0xc2, 0xc2]]

radio = NRF24(GPIO, spidev.SpiDev())
radio.begin(0, 17)
radio.setPayloadSize(32)
radio.setChannel(0x60)

radio.setDataRate(NRF24.BR_2MBPS)
radio.setPAlevel(NRF24.PA_MIN)
radio.setAutoAck(True)
radio.enableDynamicPayloads()
radio.enableAckPayload()

radio.openReadingPipe(1, pipes[1])
radio.printDetails()

radio.startListening()

while True:
 ackPL = [1]
 while not radio.available (0):
 time.sleep(1/100)

 receivedMessage = 
 radio.read(receivedMessage, radio.getDynamicPayloadSize())
 print("Received: ".format(receivedMessage))

 print("Translating the receivedMessage into unicode characters...")
 string = ""
 for n in receivedMessage:
 # Decode into standard i=unicode set
 if (n >=32 and n <= 126):
 string += chr(n)
 print(string)

 radio.writeAckPayload(1, ackPL, len(ackPL))
 print("Loaded payload reply of ".format(ackPL))

Everything seems to be alright, below are code returned by both scripts:

Translating the receivedMessage into unicode characters...

Loaded payload reply of [1]

I don't really understand why it won't connect one to other,
Both have the same wiring:

nRF24L01-Raspberry Pi (Pin#)

• GND - GND (6)


• VCC - 3,3V (1)


• CE - GPIO17 (11)


• CSN - GPIO08(24)


• SCK - GPIO11 (23)


• MOSI - GPIO10 (19)


• MISO - GPIO25 (22)


• IRQ - unconnected

I need to send information from one RPi to second to control engine via PWM.

Can i ask for help
