ota / 固件更新 / 空中升级 接入记录

ota / 固件更新 / 空中升级  即 通过手机升级BLE蓝牙设备。

固件更新最重要的就是参考 官方升级依赖库、与 官方使用Demo

官方空中升级依赖库：https://github.com/NordicSemiconductor/Android-DFU-Library

官方使用Demo：https://github.com/NordicSemiconductor/Android-nRF-Toolbox

简单使用(如果你不花太长时间就想接入的Demo，当然也由于短小而不靠谱）

1、添加依赖（我用的不是最新版）

//固件更新
implementation 'no.nordicsemi.android:dfu:1.6.1'

2、配置参数与开始升级

/**进行空中升级 [zipPath]:升级文件*/
	@WorkerThread//我是在子线程运行的,没在主线程测试过
	private fun updateDevice(zipPath: String) {
		//配置升级参数
		val initiator = DfuServiceInitiator(mMac)//设备地址
		initiator.setPacketsReceiptNotificationsEnabled(false)//启用或禁用数据包接收通知（PRN）过程
		initiator.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true)//官方Demo为true
		initiator.setDeviceName("智能手环")//设备名称,怎么写都行
		initiator.setKeepBond(false)//保持设备绑定 官方Demo为false
		initiator.setZip(File(zipPath).toUri(), zipPath)//指定更新文件(zip文件)
		val controller = //您可以使用控制器暂停，恢复或中止DFU过程。
			initiator.start(baseContext, DfuService::class.java)//调用此方法启动升级服务进行升级
	}

3、创建上文用到的 DfuService

<!--仿照官方Demo-->
<service
    android:name=".db.view.ota.DfuService"
    android:exported="true">
    <intent-filter>
        <action android:name="no.nordicsemi.android.action.DFU_UPLOAD" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</service>

class DfuService : DfuBaseService() {

   /**点击更新通知时打开此Activity*/
   override fun getNotificationTarget(): Class<out Activity> {
      return UpdateProgressActivity::class.java
   }

   override fun isDebug(): Boolean = true
}

4、在页面可见与不可见时进行升级监听

/**固件更新监听*/
private val dufProgressListener: DfuProgressListener? = object : DfuProgressListener {
   /**设备连接了*/
   override fun onDeviceConnected(deviceAddress: String?) {
      MLog.d("onDeviceConnected() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**升级准备开始*/
   override fun onDfuProcessStarting(deviceAddress: String?) {
      MLog.d("onDfuProcessStarting() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**正在连接设备*/
   override fun onDeviceConnecting(deviceAddress: String?) {
      MLog.d("onDeviceConnecting() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**更新进度开始*/
   override fun onDfuProcessStarted(deviceAddress: String?) {
      MLog.d("onDfuProcessStarted() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**升级中的回调*/
   override fun onProgressChanged(
      deviceAddress: String?, percent: Int, speed: Float, avgSpeed: Float, currentPart: Int,
      partsTotal: Int
   ) {
      MLog.d("onProgressChanged() called with: " + "deviceAddress = [" + deviceAddress + "], percent = [" + percent + "], speed = [" + speed + "], avgSpeed = [" + avgSpeed + "], currentPart = [" + currentPart + "], partsTotal = [" + partsTotal + "]")
   }

   /**设备正在断开*/
   override fun onDeviceDisconnecting(deviceAddress: String?) {
      MLog.d("onDeviceDisconnecting() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**设备断开了*/
   override fun onDeviceDisconnected(deviceAddress: String?) {
      MLog.d("onDeviceDisconnected() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**升级完成*/
   override fun onDfuCompleted(deviceAddress: String?) {
      MLog.d("onDfuCompleted() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**升级失败*/
   override fun onError(
      deviceAddress: String?, error: Int, errorType: Int, message: String?
   ) {
      MLog.d("onError() called with: " + "deviceAddress = [" + deviceAddress + "], error = [" + error + "], errorType = [" + errorType + "], message = [" + message + "]")
   }

   /**固件验证-未用*/
   override fun onFirmwareValidating(deviceAddress: String?) {
      MLog.d("onFirmwareValidating() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**未用*/
   override fun onDfuAborted(deviceAddress: String?) {
      MLog.d("onDfuAborted() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }

   /**未用*/
   override fun onEnablingDfuMode(deviceAddress: String?) {
      MLog.d("onEnablingDfuMode() called with: " + "deviceAddress = [" + deviceAddress + "]")
   }
}

override fun onResume() {
   super.onResume()
   DfuServiceListenerHelper.registerProgressListener(baseContext, dufProgressListener)
}

override fun onPause() {
   super.onPause()
   DfuServiceListenerHelper.unregisterProgressListener(baseContext, dufProgressListener)
}
