Output from the Arduino, I believe it is working fine(disregard the 11111111 I have an GPIO chip that is reporting it status)

RPi 2 and NRF24L01
Ok I have been scratching my head for a while over this(I think its a big hole now) but I have had a hard time getting the RF24Network library to work on both devices. I think I finally fixed the Arduino but the Pi is not working right. Any help would be appreciated.
Output from the Arduino, I believe it is working fine(disregard the 11111111 I have an GPIO chip that is reporting it status) Output from the Pi, these values change a lot. I know this is prob a SPI issue but I am at a loss to determine the issue. I am using the RF24 library from http://tmrh20.github.io/RF24/, I am also using the RF24Network examples.

Re: RPi 2, nrf24l01+pa+lna, and Arduino
Ok, I completely re-flashed the OS changed the config.txt to enable SPI and ran through the instructions here http://tmrh20.github.io/RF24/RPi.html. Things still are not looking right.
Any thoughts?

Re: RPi 2, nrf24l01+pa+lna, and Arduino
Ok I looked through bcm2835.h and bcm2835.c. It is trying to use /proc/device-tree/soc/ranges to pull the address block of the device. I went to that file and it appears to be empty. Any ideas still?

Re: RPi 2 and NRF24L01
So I verified the wireless works on two ardunio's just fine. Still seems to be a initialization issue with the radio on the Pi. Please, any help would be appreciated.

Check pi4.png
It looks like you have different data rates and different CRCs. They need to match if Arduino and RPi are to communicate.

Re: RPi 2 and NRF24L01
Yes retiredProgrammer is right.
Data rate needs to b the same.
Channel needs to be the same.
Transmit device need to send the address of a received device. The 5 byte device ID don't seems to match also.
You could check my post about the nRF24L01.

Re: RPi 2 and NRF24L01
This I understand, however when using the library and example I can never get it to set the correct channels. It was my understanding that when using the RF24Network library that the channel and data rate would set automatically like it dies on the Arduino. Do these settings need to be explicitly configured on the Pi? I had assumed it was a communication issue during setup of the radio.
