    I want to run multiple Arduino sensors ( temperature )and send their data directly to the Raspberry over NRF24. So I have a NRF24L01+ connected to my Raspberry B . I have the NRF24 Libary downloaded from GitHub and I proceeded according to the following howto :
    http://forum.mysensors.org/topic/1151/tutorial-raspberry-pi-nrf24l01-direct-connection

    However, when I call PiGatewaySerial , it always stops at "check wires"

    root@raspberrypi ~ # PiGatewaySerial
    Starting PiGatewaySerial...
    Protocol version - 1.4
    Created PTY '/dev/pts/1'
    Gateway tty: /dev/ttyMySensorsGateway
    check wires
    

    I have checked the cables several times . The CPU load is at 100 % .
    I had already seen this one thread , but found no solution . I have both PINs for CE connected, hardware PIN 22 and PIN hardware PIN 25.

            Not sure if it helps. I had it once, when I had a bad cable connection between one of the pins of the radio and the gateway, MOSI or MISO I forgot. That way Domoticz tried to communicate, but the messages couldn't be delivered to the nodes.

            Might be helpful to connect a serial monitor to one of your nodes?
