// We want to directly connect to the device,so we are setting the autoConnect parameter to false.
mBluetoothGatt = device.connectGatt(this,false,mGattCallback);

上面的代码表示虚假用于自动连接.但是,我在here发现了API,它说

BluetoothGatt connectGatt(Context context,boolean autoConnect,BluetoothGattCallback callback,int transport)
Connect to GATT Server hosted by this device.

我还尝试了两个标志：真和假,只有真的是工作.我使用的是版本> = Android 5.0.代码和API之间有什么不一致吗？哪个标志是正确的？如果我想进行自动连接,是否需要注意？

这是我的代码

public boolean connect(final String address) {
    if (mBluetoothAdapter == null || address == null) {
        Log.w(TAG,"BluetoothAdapter not initialized or unspecified address.");
        return false;
    }

    // PrevIoUsly connected device.  Try to reconnect.
    if (mBluetoothDeviceAddress != null && address.equals(mBluetoothDeviceAddress)
            && mBluetoothGatt != null) {
        Log.d(TAG,"Trying to use an existing mBluetoothGatt for connection.");
        if (mBluetoothGatt.connect()) {
            mConnectionState = STATE_CONNECTING;
            return true;
        } else {
            return false;
        }
    }

    final BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
    if (device == null) {
        Log.w(TAG,"Device not found.  Unable to connect.");
        return false;
    }
    // We want to directly connect to the device,so we are setting the autoConnect
    // parameter to false.
    mBluetoothGatt = device.connectGatt(this,true,mGattCallback);
    Log.d(TAG,"Trying to create a new connection.");
    mBluetoothDeviceAddress = address;
    mConnectionState = STATE_CONNECTING;
    return true;
}
