NRF24L01P dataReady() Not Found?

Hi,

Following the tutorial here: http://www.espruino.com/Wireless+Temperature+Sensor

However I get:

Uncaught Error: Function "dataReady" not found!
at line 2 col 14
while (nrf.dataReady()) {

Looking at the code here: http://www.espruino.com/modules/NRF24L01P.js

I cannot see a dataReady function?

Using an Kickstart Espruino with latest firmware loaded.
The Slave code is working and trying to send.

Just the Master code not working

Any ideas?
Thanks
R

If it helps here is the code:

SPI1.setup({sck:B3, miso:B4, mosi:B5});
var nrf = require("NRF24L01P").connect( SPI1, C5, C4 );
function onInit() {
  nrf.init([0,0,0,0,2], [0,0,0,0,1]);
}
onInit(); 


dataLine = "";
setInterval(function() {
  while (nrf.dataReady()) {
    var data = nrf.getData();
    for (var i in data) {
      var ch = data[i];
      if (ch===0 && dataLine!=="") {
        console.log(dataLine);
        // we could even save it onto an SD card using require('fs').appendFile("log.txt", dataLine+"\n");
        dataLine = "";
      } else if (ch!==0) {
        dataLine += String.fromCharCode(ch);
      }
    }
  }
}, 50);

Hi,

i guess the api has changed a little bit. You can see the change in the following commit:

https://github.com/espruino/EspruinoDocs/commit/e1b6dd998d6d3a6d6d5466dcdcc5d4a70b8ecc4f

Try: while (nrf.getDataPipe() !== undefined) {}

Thanks @possmann - yes, the API changed a few months back and I must have forgotten to update the example. I'll get that changed the next time I update the website.
