我开发了一个应用程序，它必须重新连接到某个设备上安装的服务器应用程序。我已经在某些设备上测试了我的应用程序，但是在使用Lollipop的galaxy s6上我遇到了一些问题。
这是组合：
client (peripherall) is installed on galaxy tab 10.1 kitkat
server (central role) is installed on galaxy s6 with lollipop
ok
client (peripherall) is installed on galaxy nexus 6 lollipop
server (central role) is installed on galaxy s6 with lollipop
ok
client (peripherall) is installed on galaxy s6 lollipop
server (central role) is installed on galaxy nexus 6 with lollipop
not working
在最后一个组合上，连接功能返回133状态。
这是我的代码：
public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
super.onConnectionStateChange(gatt, status, newState);
Log.d("connect", "status = " + status + " newState = " + newState);
....
Kitkat和Lollipop有什么区别？我是否必须以不同的方式处理连接？
public void new_automatization() {
automatizationInProgress = true;
Log.d("connect","new auto: si parte");
this.init();
Bluetooth.getMe().stopScan();
final String MACaddress=getDataFromPreferences("address");
final String keycode=getDataFromPreferences("unlockcode");
if(!Bluetooth.getMe().isScanning()) {
Bluetooth.getMe().startScan(new Bluetooth.ScanCallback() {
boolean deviceIsFound = false;
@Override
public void onDeviceFound(final BluetoothDevice device, int rssi,byte[] scanRecord) {
Log.d("testAlpha","dentro onDeviceFound");
if(device != null) {
String address=new String();
if(device.getName() != null) {
Log.d("testAlpha","trovato name: "+device.getName()+"mac: "+device.getAddress());
address=device.getName();
if(address.equals(MACaddress)) {
Log.d("testAlpha","mi connetto a: "+device.getName()+"mac: "+device.getAddress());
Bluetooth.getMe().stopScan();//possiamo riconnetterci
deviceIsFound=true;
setDevice(device);
unlock(keycode);
automatizationInProgress = false;
}
}
} else {
Log.i("connect","dentro onDeviceFound null");
search_ended=true;
sendMessage(DEVICE_NOT_FOUND);
automatizationInProgress = false;
}
}
});
}
}
这是startscan和stopscan功能：
@SuppressWarnings("deprecation")
public boolean startScan(ScanCallback callback, final long timeout) {
stopScan();
scanCallback = callback;
/*
if (isScanning()) {
stopScan();
return true;
}
scanCallback = callback;
// Stops scanning after a pre-defined scan period (10s).
stopTimer = new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(timeout);
} catch (InterruptedException e) {
Log.i("debug","interrupted");
return;
}
Log.i("debug","bluetooth: inizia lo stopscan()");
if(!isScanning())
return;
Log.i("debug","amgbluetooth: pre scansione");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
BluetoothLeScanner scanner = bluetoothAdapter
.getBluetoothLeScanner();
scanner.stopScan(scanCallbackAfterLollipop);
scanning = false;
} else {
bluetoothAdapter.stopLeScan(scanCallbackBeforeLollipop);
scanning = false;
}
Log.i("debug","amgbluetooth:stopTimer, invio null");
if(!Thread.currentThread().isInterrupted())
scanCallback.onDeviceFound(null, 0, null);
}
});
stopTimer.start();*/
pippo.removeCallbacks(solPippo);
pippo.postDelayed(solPippo, timeout);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Log.i("finalT","amgbluetooth: inizia lo startscan() LL");
BluetoothLeScanner scanner = bluetoothAdapter.getBluetoothLeScanner();
scanning = true;
scanCallbackAfterLollipop = new ScanCallback() {
@Override
public void onScanResult(int callbackType, ScanResult result) {
super.onScanResult(callbackType, result);
Log.d("finalT", "Single Result: "+result.getDevice().getName());
processResult(result);
/*
scanCallback.onDeviceFound(result.getDevice(), result.getRssi(), result.getScanRecord().getBytes());*/
}
@Override
public void onBatchScanResults(List<ScanResult> results) {
Log.d("finalT", "onBatchScanResults: "+results.size()+" results");
/*

processResult(result);
}*/
}
@Override
public void onScanFailed(int errorCode) {
Log.w("finalT", "LE Scan Failed: "+errorCode);
}
private void processResult(ScanResult result) {
BluetoothDevice device = result.getDevice();
Log.i("finalT", "New LE Device: " + device.getName() + " @ " + result.getRssi());
scanCallback.onDeviceFound(result.getDevice(),
result.getRssi(), result.getScanRecord()
.getBytes());
//stopScan();
}
};
ScanSettings settings = new ScanSettings.Builder().setScanMode(ScanSettings.SCAN_MODE_BALANCED).setReportDelay(0).build();
scanner.flushPendingScanResults(scanCallbackAfterLollipop);
scanner.startScan(null,settings,scanCallbackAfterLollipop);
return true;
} else {
Log.i("finalT","amgbluetooth: inizia lo startscan() < LL");
scanning = true;
scanCallbackBeforeLollipop = new LeScanCallback() {
@Override
public void onLeScan(BluetoothDevice device, int rssi,
byte[] scanRecord) {
Log.i("finalT","device trovato: "+device.getName());
scanCallback.onDeviceFound(device, rssi, scanRecord);
}
};
return bluetoothAdapter.startLeScan(scanCallbackBeforeLollipop);
}
}
public void stopScan() {
Log.i("debug1","stopScan()");
if(isScanning()) {
Log.i("debug","stopScan() inside if");
//stopTimer.interrupt();
pippo.removeCallbacks(solPippo);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
BluetoothLeScanner scanner = bluetoothAdapter.getBluetoothLeScanner();
scanner.stopScan(scanCallbackAfterLollipop);
scanning = false;
} else {
bluetoothAdapter.stopLeScan(scanCallbackBeforeLollipop);
scanning = false;
}
}
}
并在unlock()我调用connect函数。
P.S。：我要连接的设备名称（nexus 6）位于macaddress变量中。
