HBluetooth
封装了支持经典蓝牙和低功耗蓝牙扫描，连接，以及通信的库。附带使用例子。该库后续会持续升级维护，敬请关注...
一.集成方式
To get a Git project into your build:
Step 1. Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
implementation 'com.github.g-HJY:Kotlin-HBluetooth:V1.0.3'
}
二.使用介绍
1.第一步，使用前先实例化HBluetooth（全局单例）,并且必须调用enableBluetooth()方法开启蓝牙功能：
HBluetooth.getInstance(this).enableBluetooth()
2.开启蓝牙能力后，接着你就可以开始进行蓝牙设备扫描，其中，type 为蓝牙设备类型（经典蓝牙或低功耗蓝牙）：
HBluetooth.getInstance(this)
.scanner()
.scan(type, object : ScanCallBack {
override fun onScanStart() {
Log.i(TAG, "开始扫描")
}
override fun onScanning(scannedDevices: List<BluetoothDevice>?, currentScannedDevice: BluetoothDevice?) {
Log.i(TAG, "扫描中")
if (scannedDevices != null && scannedDevices.size > 0) {
list!!.clear()
list.addAll(scannedDevices)
adapter!!.notifyDataSetChanged()
}
}
override fun onError(errorType: Int, errorMsg: String?) {}
override fun onScanFinished(bluetoothDevices: List<BluetoothDevice>?) {
Log.i(TAG, "扫描结束")
if (bluetoothDevices != null && bluetoothDevices.size > 0) {
list!!.clear()
list.addAll(bluetoothDevices)
adapter!!.notifyDataSetChanged()
}
}
})
或者，如果你想在第一步操作后直接进行扫描，则可以这样调用：
HBluetooth.getInstance(this)
.enableBluetooth()
.scan(type, object : ScanCallBack {
override fun onScanStart() {
Log.i(TAG, "开始扫描")
}
override fun onScanning(scannedDevices: List<BluetoothDevice>?, currentScannedDevice: BluetoothDevice?) {
Log.i(TAG, "扫描中")
if (scannedDevices != null && scannedDevices.size > 0) {
list!!.clear()
list.addAll(scannedDevices)
adapter!!.notifyDataSetChanged()
}
}
override fun onError(errorType: Int, errorMsg: String?) {}
override fun onScanFinished(bluetoothDevices: List<BluetoothDevice>?) {
Log.i(TAG, "扫描结束")
if (bluetoothDevices != null && bluetoothDevices.size > 0) {
list!!.clear()
list.addAll(bluetoothDevices)
adapter!!.notifyDataSetChanged()
}
}
})
3.一旦扫描到设备，你就可以找到目标设备并连接：
HBluetooth.getInstance(this)
.connector()?
.connect(device, object : ConnectCallBack {
override fun onConnecting() {
Log.i(TAG, "连接中...")
}
override fun onConnected(sender: Sender?) {
Log.i(TAG, "连接成功,isConnected:" + mHBluetooth!!.isConnected)
//调用发送器发送命令
sender?.send(byteArrayOf(0x01, 0x02), object : SendCallBack {
override fun onSending() {
Log.i(TAG, "命令发送中...")
}
override fun onReceived(dataInputStream: DataInputStream?, bleValue: ByteArray) {
Log.i(TAG, "onReceived->$dataInputStream---$bleValue")
}
})
}
override fun onDisConnecting() {
Log.i(TAG, "断开连接中...")
}
override fun onDisConnected() {
Log.i(TAG, "已断开连接,isConnected:" + mHBluetooth!!.isConnected)
}
override fun onError(errorType: Int, errorMsg: String) {
Log.i(TAG, "错误类型：$errorType 错误原因：$errorMsg")
}
})
4.设备连接成功后，你可以开始跟设备进行通信：
HBluetooth.getInstance(this)
.sender()?
.send(byteArrayOf(0x01, 0x02), object : SendCallBack {
override fun onSending() {
Log.i(TAG, "命令发送中...")
}
override fun onReceived(dataInputStream: DataInputStream?, bleValue: ByteArray) {
Log.i(TAG, "onReceived->$dataInputStream---$bleValue")
}
})
5.最后，调用以下方法去主动断开连接并释放资源：
HBluetooth.getInstance(this).release()
