close()和disconnect()之间的区别? [英] Difference between close() and disconnect()?

问题描述

Android蓝牙低功耗API实现了一种方法来连接到设备connectGatt()，但是实现了两种方法来关闭连接disconnect()和close().

Android Bluetooth Low Energy API implements 1 method to connect to the device connectGatt() but 2 methods to close the connection disconnect() and close().

文档说:

• disconnect():断开建立的连接，或取消连接尝试 目前正在进行中.

• disconnect(): Disconnects an established connection, or cancels a connection attempt currently in progress.

close():完成后，应用程序应尽早调用此方法 这个GATT客户.

close(): Application should call this method as early as possible after it is done with this GATT client.

的源代码BluetoothGatt.java 显示close()取消注册应用程序，disconnect()断开客户端连接.但是，它没有说出实际含义.我的意思是，如果只有一种方法可以连接到客户端，为什么有两种方法可以关闭/断开连接?

The source code of BluetoothGatt.java shows that close() unregisters the application and disconnect() disconnect the client. However it does not say what that actually means. I mean, if there is only 1 way to connect to the client, why there are 2 ways to close/disconnect the connection?

推荐答案

使用disconnect()，您以后可以调用connect()并继续该循环.

With disconnect() you can later call connect() and continue with that cycle.

一旦您致电close()，您就完成了.如果要再次连接，则必须再次调用BluetoothDevice上的connectGatt()；否则，将重新调用. close()将释放BluetoothGatt拥有的所有资源.

Once you call close() you are done. If you want to connect again you will have to call connectGatt() on the BluetoothDevice again; close() will release any resources held by BluetoothGatt.
