Extended usage of the decode function

Get more information from LoRaObject variable.

Example

function Decode(fPort, bytes) {
  var decoder = {};
  if (fPort == 85) {
    decoder.sensor = LoRaObject.devEUI;
    decoder.vendor = "Milesight-IoT";
    decoder.time = LoRaObject.time;
    decoder.raw = bytes;
  }
  return decoder;
}

Output Result

{
  "sensor": "24e1641092176759",
  "vendor": "Milesight-IoT",
  "time": "2020-0327T12:39:05.547336Z",
