Hello All!
I am really new to this, and I need som help.
I have connected the nrf24 to the pins as it says, and I have enabled SPI.
But still do I get check wires when I try to start up the server.
Anyone had any idea?

If wires are connected correctly and you use RPi image it should work.

That's what I thought too. I use those nrf24 on arduino without problems. I have checked all over internet of connections, but still it doesn't work. my raspberry is a B+ V1.2. if I go in to /dev/ and run ls, I get spidev 0.0 and spidev 1.0. So if I don't have missed anything more then I should have SPI regarding to software, and then it should be an hardware issue. Or am I wrong?

I think I need a little bit rest. :)
I have the B+ bord, should start to count the amount of pins. :)

I have another question though.
When using the ESP8266, how is it connected to Rpi?
Do you take the 3.3v from pin 1 as you do for the NRF24?

ESP8266 is connected only to Arduino. RPi uses network cable or USB WiFi dongle.

it's a great piece of software this.
I have the server up and running.
My problem now is that I can't connect my nodes.
Is there any special settings for the radio that I have to take care of?

Channel is set to 90
base radio id is: 0xA8A8E1FC00
data rate is set to 250kps
Power amplifi leveö is set to PA MAX
