running ble on ESP-IDF release 3.0,

I'm back again.
Here is my test code.

// esp32test_00

var darray = {};
var count = 0;


function getDewpoint(temp, humi) {

  var C = {
    a1 : 8.1332,
    b1 : 1762.39,
    c1 : 235.66
  };

  PP = Math.pow(10,C.a1 - C.b1 / (this.temp + C.c1));
  this.dewp = -((C.b1 / (Math.log(this.humi * PP / 100) / Math.log(10) - C.a1)) + C.c1);
  return this.dewp.toFixed(2);
}

function bprint(dada, navn) {
  if(dada != 'undefined') {
    humi = dada.data[8] / 2;
    temp = dada.data[9] + dada.data[10] / 100;
    if(temp >128) {temp = 128 - temp;}
    bati = (dada.data[19] * 256 + dada.data[20]);
    dewi = getDewpoint(temp, humi);
    console.log(navn +
                dada.rssi +
                '  ' + temp.toFixed(2) +
                '  ' + humi.toFixed(1) +
                '  ' + dewi +
                '  ' + bati);
  }
}
