如何在Android设备上通过MAC地址断开蓝牙连接？

Question

我使用了以下代码，尽管调试时所有步骤都消失了，但是我无法断开蓝牙连接。

/**
 * Disconnect
 *
 * @param address Mac Address
 */
public void disConnectDevice(String address) {
    BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
    BluetoothGatt mBluetoothGatt = device.connectGatt(this, false, gattCallback);
    mBluetoothGatt.disconnect();
}

private BluetoothGattCallback gattCallback = new BluetoothGattCallback() {
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        super.onConnectionStateChange(gatt, status, newState);
        gatt.close();
    }
};

from [TransactionMasterReport]
where PostDate between '12/30/2017' and '07/1/2018'
