Android蓝牙客户端，支持经典蓝牙和低功耗蓝牙BLE，增加协程Flow扩展版本CoroutineClient，适配最新Android系统版本
- 支持蓝牙权限自动检测、申请
- 支持失败自动重连、重发、重读
- 支持设置重试次数（协程版本暂不支持）
- 支持设置超时时间
- 支持连接设备后指定serviceUid，修改mtu
- 支持BLE设置多个notifyUid监听数据
- 支持ChannelFlow
Compose版蓝牙助手，基于当前库开发: https://github.com/zhzc0x/BluetoothAssistant
添加gradle依赖
repositories {
mavenCentral()
}
dependencies {
implementation("com.zhzc0x.bluetooth:client-android:1.0.2")
}代码示例
val bluetoothClient = BluetoothClient(context, ClientType.BLE\ClientType.CLASSIC, serviceUid)
bluetoothClient.startScan(30000, onEndScan={
//子线程
......
}){ device ->
//子线程
......
}
bluetoothClient.connect(device, mtu){ connectState ->
//子线程
if(connectState == ConnectState.CONNECTED){
......
}
}
//协程版本
val bluetoothClient = CoroutineClient(context, ClientType.BLE\ClientType.CLASSIC, serviceUid)
lifecycleScope.launch {
bluetoothClient.startScan(30000, onEndScan={
//主线程
......
}).collect{ device ->
//此处线程取决于FLow.collect所在的线程
......
}
}
lifecycleScope.launch {
bluetoothClient.connect(device, 85, 15000).collect{ connectState ->
//此处线程取决于FLow.collect所在的线程
if(connectState == ConnectState.CONNECTED){
......
}
}
}
