Android蓝牙低功耗readRemoteRssi

final BluetoothManager bluetoothManager = (BluetoothManager) getSystemservice(Context.bLUETOOTH_serviCE);
    BluetoothAdapter mBluetoothAdapter = bluetoothManager.getAdapter();
    BluetoothGatt gatt;

    mBluetoothAdapter.startLeScan(new LeScanCallBACk() {

        @Override
        public void onLeScan(BluetoothDevice device,int RSSi,byte[] record) {
            gatt = device.connectGatt(getApplicationContext(),false,new BluetoothGattCallBACk() {
                @Override
                public void onReadRemoteRSSi(BluetoothGatt gatt,int status) {
                    super.onReadRemoteRSSi(gatt,RSSi,status);
                    Log.d(tag,"RSSi is : " + RSSi);
                }
            });
        }
    });

    gatt.readRemoteRSSi(); //returns true

将readRemoteRSSi()放在BluetoothGattCallBACk的回调onConnectionStateChange()中.

private final BluetoothGattCallBACk mGattCallBACk = new BluetoothGattCallBACk() {
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt,int status,int newStatE) {
        String intentAction;
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            intentAction = ACTION_GATT_CONNECTED;
            mConnectionState = STATE_CONNECTED;
            Boolean RSSiStatus = mBluetoothGatt.readRemoteRSSi();
            broadcastupdate(intentAction);
            // Attempts to discover services after successful connection.
            Log.i(tag,"AttempTing to start service discovery:" +
                    mBluetoothGatt.discoverservices());
        }
    }
};

并且还将onReadRemoteRSSi放在BluetoothGattCallBACk函数中

@Override
public void onReadRemoteRSSi(BluetoothGatt gatt,int status){
    if (status == BluetoothGatt.GATT_succesS) {
        Log.d(tag,String.format("BluetoothGatt ReadRSSI[%d]",RSSi));
    }
}
