蓝牙通信

基于谷歌官方经典蓝牙示例封装

快速使用

implementation 'com.ccand99.mark:bluetoothx:1.0.1'

权限说明

需要动态权限申请，demo有
权限声明

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature android:name="android.hardware.bluetooth_le" android:required="false"/>

初始化方式：

blueTooth = BlueTooth.getInstance(this, REQUEST_ENABLE_BT, mHandler)

其中this必须为Activity
REQUEST_ENABLE_BT，是允许蓝牙开启返回值等于onActivityResult(requestCode: Int, resultCode: Int, data: Intent?)中的requestCode
mHandler为处理带回的消息

使用方式

被连接方需要在主动调用start()推荐在onResume()

主动连接方调用blueTooth?.chooseDeviceConnect()，然后选择已配对完成的设备会自动连接。

通用常量

kt文件下

// Message types sent from the BluetoothChatService Handler
const val  MESSAGE_STATE_CHANGE = 1
const val MESSAGE_READ = 2
const val MESSAGE_WRITE = 3
const val MESSAGE_DEVICE_NAME = 4
const val MESSAGE_TOAST = 5

// Key names received from the BluetoothChatService Handler
const val DEVICE_NAME = "device_name"
const val TOAST = "toast"

BlueTooth下

// Constants that indicate the current connection state
const val STATE_NONE = 0 // we're doing nothing
const val STATE_LISTEN = 1 // now listening for incoming connections
const val STATE_CONNECTING = 2 // now initiating an outgoing connection
const val STATE_CONNECTED = 3 // now connected to a remote device

v1.0.1

1.新整getRemoteDevice(mac: String) 可以用mac获得BluetoothDevice 然后用connect(device: BluetoothDevice, secure: Boolean)直接连接

2.可修改BlueTooth.MY_UUID_INSECURE 和 BlueTooth.MY_UUID_SECURE 请在getInstance之前修改

3.修改showDeviceListDialog()方法名字为chooseDeviceConnect()
