multiple nrf24 sending data to one master

In case anyone wants it, here is my code for multiple TX with one RX:

RX:

SPI1.setup({sck:A5, miso:A6, mosi:A7});

var nrf = require("NRF24L01P").connect( SPI1, B0, B1 );

var recvData, lastData, lastUpdated;

function onInit() {
  recvData = [];
  lastData = [];
  lastUpdated = [];
  lastUploaded = getTime();
  
  nrf.init([0,0,0,0,1]/* rx addr 1*/, [0,0,0,0,2] /* tx addr */);
  nrf.setDataRate(250000);
  // set receive addresses
  nrf.setRXAddr([1,0,0,0,1], 2);
  nrf.setRXAddr([2,0,0,0,1], 3);
  nrf.setRXAddr([3,0,0,0,1], 4);
  nrf.setRXAddr([4,0,0,0,1], 5);

   setInterval(checkNRF, 50);
}

function checkNRF() {
  var pipe;
  while ((pipe=nrf.getDataPipe())!==undefined) {
    nrf.getData().map(function(ch) {
      if (recvData[pipe]===undefined) recvData[pipe]="";
      if (ch===0 && recvData[pipe]!=="") {
        var d = JSON.parse(recvData[pipe]);
        if (d) {
          lastData[pipe] = d;
          lastUpdated[pipe] = getTime();
        }
        recvData[pipe] = "";
      } else if (ch!==0) {
        recvData[pipe] += String.fromCharCode(ch);
      }
    });
  }
}

TX 1:

SPI1.setup({sck:A5, miso:A6, mosi:A7});
var nrf = require("NRF24L01P").connect( SPI1, B0, B1 );
function onInit() {
  nrf.init([0,0,0,0,2]/* rx addr */, [0,0,0,0,1]/*tx must match receiver's RX*/);
  nrf.setDataRate(250000);
}
function sendData() {
  var data = { temp : E.getTemperature().toFixed(2), bat : E.getAnalogVRef().toFixed(2) };
  nrf.setEnabled(true);
  nrf.sendString(JSON.stringify(data));
  nrf.setEnabled(false);
}
onInit();
setInterval(sendData, 20000);
setDeepSleep(1);

TX2:

SPI1.setup({sck:A5, miso:A6, mosi:A7});
var nrf = require("NRF24L01P").connect( SPI1, B0, B1 );
function onInit() {
  nrf.init([0,0,0,0,2]/* rx addr */, [1,0,0,0,1]/*tx must match receiver's RX*/);
  nrf.setDataRate(250000);
}
function sendData() {
  var data = { temp : E.getTemperature().toFixed(2), bat : E.getAnalogVRef().toFixed(2) };
  nrf.setEnabled(true);
  nrf.sendString(JSON.stringify(data));
  nrf.setEnabled(false);
}
onInit();
setInterval(sendData, 20000);
setDeepSleep(1);

and so on... All that changes is the TX address.
