使用Nordic芯片的手環OTA（android）

我司現在的手環全部切換到使用nordic方案了，現參照官網上的demo整理一下其固件升級步驟如下

• 第一步:添加依賴

  compile ‘no.nordicsemi.android:dfu:1.0.4’

• 第二步：繼承DfuBaseService（不要忘記在清單文件中注冊）

public class DfuService extends DfuBaseService {@Overrideprotected Class<? extends Activity> getNotificationTarget() {return null;} }

• 第三步：在升級activity中添加如下代碼

@Overrideprotected void onResume() {super.onResume();DfuServiceListenerHelper.registerProgressListener(this, mDfuProgressListener);}@Overrideprotected void onPause() {super.onPause();DfuServiceListenerHelper.unregisterProgressListener(this, mDfuProgressListener);}private final DfuProgressListener mDfuProgressListener = new DfuProgressListener() {@Overridepublic void onDeviceConnecting(String deviceAddress) {Log.e("dfu", "onDeviceConnecting");}@Overridepublic void onDeviceConnected(String deviceAddress) {Log.e("dfu", "onDeviceConnected");}@Overridepublic void onDfuProcessStarting(String deviceAddress) {Log.e("dfu", "onDfuProcessStarting");showProgressDialog();}@Overridepublic void onDfuProcessStarted(String deviceAddress) {Log.e("dfu", "onDfuProcessStarted");}@Overridepublic void onEnablingDfuMode(String deviceAddress) {Log.e("dfu", "onEnablingDfuMode");}@Overridepublic void onProgressChanged(String deviceAddress, int percent, float speed, float avgSpeed, int currentPart, int partsTotal) {Log.e("dfu", "onProgressChanged" + percent);progressDialog.setProgress(percent);}@Overridepublic void onFirmwareValidating(String deviceAddress) {Log.e("dfu", "onFirmwareValidating");}@Overridepublic void onDeviceDisconnecting(String deviceAddress) {Log.e("dfu", "onDeviceDisconnecting");}@Overridepublic void onDeviceDisconnected(String deviceAddress) {Log.e("dfu", "onDeviceDisconnected");}@Overridepublic void onDfuCompleted(String deviceAddress) {Log.e("dfu", "onDfuCompleted");stopDfu();progressDialog.dismiss();Toast.makeText(mContext, "升級成功", Toast.LENGTH_SHORT).show();}@Overridepublic void onDfuAborted(String deviceAddress) {Log.e("dfu", "onDfuAborted");progressDialog.dismiss();Toast.makeText(mContext, "升級失敗，請重新點擊升級。", Toast.LENGTH_SHORT).show();}@Overridepublic void onError(String deviceAddress, int error, int errorType, String message) {Log.e("dfu", "onError");stopDfu();progressDialog.dismiss();Toast.makeText(mContext, "升級失敗，請重新點擊升級。", Toast.LENGTH_SHORT).show();}};private void stopDfu() {Intent intent = new Intent(this, DfuService.class);stopService(intent);}private void showProgressDialog() {progressDialog = new ProgressDialog(this);progressDialog.setTitle("正在升級");progressDialog.setMessage("請稍等。。。");progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);progressDialog.setMax(100);progressDialog.setCancelable(false);progressDialog.show();}

• 第四步：手機向手環發送進入OTA狀態的命令，成功進入后使用下面代碼：

//進入OTA前的mac地址 String mac = SPUtil.getStringValue(AppConstant.SP_KEY_DEVICE_ADDRESS, null); //進入OTA后的mac地址 （在原mac上加1）final String newMac = mac.substring(0, 15) + HexUtil.algorismToHEXString(HexUtil.hexStringToAlgorism(mac.substring(15, 17)) + 1); //搜索新mac設備BleManager.viseBluetooth.setScanTimeout(10000).startScan(new PeriodMacScanCallback(newMac) {@Overridepublic void scanTimeout() {}@Overridepublic void onFind(BleDevice bleDevice) {//傳入OTA文件的uri開始空升new DfuServiceInitiator(newMac).setDisableNotification(true).setZip(uri).start((getBaseContext()), DfuService.class);}});
