Location tracking

Well, amusingly, my prints are actually throttled, I just didn't want to overcomplicate the code

function throttle(func, wait, options) {
  var context, args, result;
  var timeout = null;
  var previous = 0;
  if (!options) options = {};
  var later = function() {
    previous = options.leading === false ? 0 : Date.now();
    timeout = null;
    result = func.apply(context, args);
    if (!timeout) context = args = null;
  };
  return function() {
    var now = Date.now();
    if (!previous && options.leading === false) previous = now;
    var remaining = wait - (now - previous);
    context = this;
    args = arguments;
    if (remaining <= 0 || remaining > wait) {
      if (timeout) {
        clearTimeout(timeout);
        timeout = null;
      }
      previous = now;
      result = func.apply(context, args);
      if (!timeout) context = args = null;
    } else if (!timeout && options.trailing !== false) {
      timeout = setTimeout(later, remaining);
    }
    return result;
  };
}


function printDeviceData(device) {
  try {
    Bluetooth.println(JSON.stringify(device));
  } catch (err) {}
}

function getDevices() {
  const throttledPrint = throttle(printDeviceData, 1000);
  
  NRF.setScan(function(device) {
    if (device.name && device.name.indexOf('Puck.js') >= 0) {
      const data = device.data.toString().substr(-1);

      if (!devices[device.name]) {
        devices[device.name] = {
          name: device.name,
          rssi: device.rssi,
          data: data,
        };
      }
      
      const oldDevice = devices[device.name];
      
      if (device.rssi !== oldDevice.rssi) {
        devices[device.name].rssi = device.rssi;
        
        throttledPrint(devices[device.name]);
      }
    }
  });
}
