I'm testing RPi pongtest and Arduino pingtest.

It seems that RPi is able to receive but not to send data back. I tested with 2 arduino communicating, and it works. But when I use RPi it doesn't. Here is my printDetails, and a part of the output. Other thing that is strange is that RPi doesn't receive a lot of messages on arduino it receive all of then, maybe because RPi is executing more tasks on background and receiving messages while pongtest is sleeping?

You can see that Pipes 0 and 1 are correct since they are invert from one to other. So do you have any idea what could this be? I'm thinking that maybe a RPi timing issue. Mine RPi is Version 1.0 with 256 ram running "Linux raspberrypi 3.6.11+ #371 PREEMPT Thu Feb 7 16:31:35 GMT 2013 armv6l GNU/Linux"

RPi pongtest:

It would be nice to have a clean compile without the "hide warnings" option.

after the scanner example in rpi the nrf needs to be resetted to make it work in the other examples.

I can do the following to reset the config:
radio.write_register(0x00,0x0f);
only after modifying the RF24.h file to make the method public instead of protected - this enables comms to resume without power cycle.

This seems not to work

I am trying to establish a connection between my Arduino Uno and RPi.

I followed the connections and run the Getting Started example on the Arduino and "pongtest" on the Pi

I cannot establish communication between the 2 devices. I have checked, double checked and triple checked the connections. They're all correct. Using connections as mentioned in http://hack.lenotta.com/arduino-raspberry-pi-switching-light-with-nrf24l01/

Also, both devices are in the same room so range is not a problem.

Rename functions or, when the functions and classes are the same, use the wiring option.

Hi，How into the next cross compiler environment in centos 6?

the cs is toggled during multi byte spi. The one in PinDA works better but needs some cleanup. The GPIO is not needed for CS when using the hardware spi.
