[solved] TX not received 255? (NRF24L01+)

Hello everybody,

the tutorial on "NRF24L01+" is not working for me:
http://www.espruino.com/NRF24L01P

It's driving me crazy, because I always get the following message on the master:

>nrf.sendCommand("1+2", function(r) { print("=="+r); });
TX not received 255
TX not received 255
TX not received 255
=undefined

Any suggestion are welcomed very much, as I need an working NRF24L01+ for a futur project!

Thank you very much,

Stefan

My connections:

NRF24L01+	Name	Espruino	Type
1		GND	GND		GND
2		3.3V	3.3		3.3v
3		CE	A0		GPIO Out
4		CSN	A1		GPIO Out
5		SCK	B3		SPI SCK
6		MOSI	B4		SPI MOSI
7		MISO	B5		SPI MISO
8		IRQ	unused		GPIO In

My testcode:

Slave:

SPI1.setup({sck:B3, miso:B4, mosi:B5});
var nrf = require("NRF24L01P").connect( SPI1, A1, A0 );
function onInit() {
  nrf.init([0,0,0,0,1], [0,0,0,0,2]);
}
function toggle1(){
  on1=!on1;
  digitalWrite(LED1,on1);
}
onInit();
setInterval(function() {
  toggle1();
  nrf.slaveHandler();
}, 50);

Master:

SPI1.setup({sck:B3, miso:B4, mosi:B5});
var nrf = require("NRF24L01P").connect( SPI1, A1, A0 );
function onInit() {
  nrf.init([0,0,0,0,2], [0,0,0,0,1]);
}
onInit();
setInterval(function() {
  nrf.masterHandler();
}, 50);
