getting null device name while calling startDeviceScan

[scrapecoder]

const scanAndConnect = () => {
bleManager.startDeviceScan(
  null,
  {allowDuplicates: false},
  (error, device) => {
    if (error) {
      if (error.message === 'BluetoothLE is powered off') {
        bleManager.enable();
      }
      // Handle error (scanning will be stopped automatically)
      return;
    }

    // Check if it is a device you are looking for based on advertisement data
    // or other criteria.

    if (device && device.name) {
      console.log('device name====>', device.name);
    }
    console.log('device-<', device);
  },
);
};

HI, can you use some external scanning application to see if the name is there or it is also null?

I have a few questions:

• What advertising do you use (BT 5 Advertising extension or legacy)
• What is the name (how long and does it contain special characters) of the device you are looking for?
• What device do you use (what version of BT)

We have added a scanning option for BT 5 advertisers (disable legacy scan - https://github.com/dotintent/react-native-ble-plx/wiki/Device-Bonding) and name mapping for Android.
