Ich habe das gleiche Problem. Aber ich benutze das Phonegap CLI. Und das folgende Plugin: https://github.com/randdusing/cordova-plugin-bluetoothle
füge ich das Plugin mit dem Befehl:
$ phonegap plugin add cordova-plugin-bluetoothle
Ich habe hinzugefügt Plattform Android und iOS.
Also im Ordner plugins befindet sich der Ordner cordova-plugin-bluetoothle, der höchstwahrscheinlich ein gültiges Plugin-Paket ist. Auch in den Plugin-Ordner gibt es die android.json und ios.json Datei den Abschnitt enthält:
"cordova-plugin-bluetoothle": {
"PACKAGE_NAME": "com.phonegap.helloworld"
},
in plaforms/Android gibt es die android.json Datei enthält:
{
"xml": "<feature name=\"BluetoothLePlugin\"><param name=\"android-package\" value=\"com.randdusing.bluetoothle.BluetoothLePlugin\" /></feature>",
"count": 1
},
in Plattformen/ios dort die ios.json Datei enthält:
{
"xml": "<feature name=\"BluetoothLePlugin\"><param name=\"ios-package\" value=\"BluetoothLePlugin\" /></feature>",
"count": 1
},
I 23. Android SDK API ausgerichtet haben als die readme sagt ...
Wie ich gerade das Hello-World-Beispiel geändert habe, um bluetoothle zu initialisieren, nachdem das Deviceready-Ereignis ausgelöst hat.
Also wo könnte das Problem sein, so dass die Bluetooth-Variable nicht in der index.js Code definiert ist, wenn das Gerät bereit ist?
Also hier der vollständige Code von index.js:
var bluetoothle;
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'
onDeviceReady: function() {
app.receivedEvent('deviceready');
console.log("platform: " + device.platform);
if(bluetoothle) {
console.log("bluetooth is not defined!");
} else {
console.log("bluetooth is not defined!");
}
console.log("yhea managed to initialize Bluetooth LE!");
},
// Update DOM on a Received Event
receivedEvent: function(id) {
var parentElement = document.getElementById(id);
var listeningElement = parentElement.querySelector('.listening');
var receivedElement = parentElement.querySelector('.received');
listeningElement.setAttribute('style', 'display:none;');
receivedElement.setAttribute('style', 'display:block;');
console.log('Received Event: ' + id);
}
};
Und der vollständige Code des Index.html:

* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
