Hi to all,
by this article,http://tronixstuff.wordpress.com/2011/05/13/tutorial-arduino-and-the-spi-bus/
I understood that the SPI protocol of an Arduino (UNO/MEGA) can't work at same time with an arduino ethernet shield and aNRF24L01+ transceiver because both devices use the SPI. Also, you have to duplicate the SPI bus.
So, to avoid these problems, I think that using an Arduino Ethernet is possible to use the NRF24L01+ and the ethernet cable without problem on SPI coonection.
What do you think about this? Is correct?
Thank you in advance,
