Received advertising data format is not ArrayBuffer

Version

• react-native-ble-manager v5.0.4
• react-native v0.45.1
• Android v5.0.2

Expected behavior

From your example code, it is shown that in handleDiscoverPeripheral, the peripheral object will have a advertising key and it will be an ArrayBuffer ( the same thing also specified in cordova-plugin-ble-central documentation ). it can then be easily converted to UInt8Array or String.

Actual behavior

When I logged the peripheral object it is showing that the advertising key is an object with two keys: ‘CDVType’ and ‘data’. I tried to convert this object to UInt8Array using new Uint8Array(peripheral.advertising) and to String using String.fromCharCode.apply(null, new Uint16Array(buf)). But failed. It is showing an empty result. Am I missing something?

@marcosinigaglia How do you think about this idea (using bytes rather than base64 for advertising data) ? I can try to make a PR about this one, for both iOS and Android.

On LollipopScanner onScanResult i get the advertising data like this

SparseArray<byte[]> array = result.getScanRecord().getManufacturerSpecificData(); byte[] manufacture_data = [] if(array.valueAt(0) != null){ manufacture_data = array.valueAt(0); } and you get an array of bytes with the manufacturerData inside.
