Android advertising data is received as an ArrayBuffer . You need to convert it to a human readable string using javascripts String.fromCharCode method :

let stringResult = String.fromCharCode.apply(null, new Uint8Array(buffer));

Where buffer is the advertising property of you response object. You can find the ionic-native docs for BLE here .
