1 Environment configuration

1.1 Add SDK to your project

Copy crpblelib-*.aar to the project's libs directory. If there is an old version of the aar package in it, please delete it.

1.2 Declare permissions

Configure permissions in AndroidManifest.xml

x

1.3 Declaration component

Please declare the following components in the application tag

xxxxxxxxxx

1.4 Obfuscation rules

Perform the following configuration when generating apk for code obfuscation

xxxxxxxxxx-keep class com.crrepa.ble.** { *; }

2 Usage

The following contains all the functions supported by the MoYoung Watch, and a certain watch only supports part of the functions. To find out if your watch supports a feature, contact us.

2.1 Create the CRPBleClient

CRPBleClient is the entry point of the SDK. The client needs to maintain an instance of CRPBleClient. It is recommended to initialize CRPBleClient in Application.onCreate().

xxxxxxxxxxCRPBleClient bleClient = CRPBleClient.create(context);

2.2 Scan BLE device

1. Start scan

   Normal scanning can be started with permission enabled and Bluetooth enabled. When the watch is found during scanning, it is called back by CRPScanCallback.onScanning(). After the scan is finished, all the watchs found during the scan are recalled by CRPScanCallback.onScanComplete(). The scan duration can be set in milliseconds. Because the Bluetooth scan operation is time-consuming, the recommended scan time is 10 seconds.

xxxxxxxxxxbleClient.scanDevice(scanCallback, 10 * 1000);

2. Cancel scan

   Stop scanning while scanning, and canceling scanning also triggers CRPScanCallback.onScanComplete().

xxxxxxxxxxbleClient.cancelScan();

2.3 Connect

1. Connect

   Get the Mac Address to the watch by scanning the CRPScanDevice of the callback. Connect to the watch via CRPBleDevice.connect() and callback state via CRPBleConnectionStateListener.onConnectionStateChange() . It is recommended to increase the appropriate delay when the reconnection is disconnected, so that the system can recover resources and ensure the connection success rate.

xxxxxxxxxxString address = CRPScanDevice.getDevice().getAddress();CRPBleDevice bleDevice = bleClient.getBleDevice(address);CRPBleConnection bleConnection = bleDevice.connect();bleConnection.setConnectionStateListener(bleConnectionStateListener);

2. Reconnect

   There are two ways to reconnect:

• New GATT connection (recommend)

  xxxxxxxxxx// close GATT CRPBleConnection.close();// delay 3 secondsString address = CRPScanDevice.getDevice().getAddress();CRPBleDevice bleDevice = bleClient.getBleDevice(address);CRPBleConnection bleConnection = bleDevice.connect();bleConnection.setConnectionStateListener(bleConnectionStateListener);

• Continue to connect

  xxxxxxxxxxCRPBleConnection.connect();

2.4 Time

1. Sync Time

   Keep the watch and the phone in the same time.

   xxxxxxxxxxbleConnection.syncTime();

2. Set Time System

   Sets the time system of the watch.

   xxxxxxxxxxbleConnection.sendTimeSystem(byte type);

   CRPTimeSystemType:

   TIME_SYSTEM_12	TIME_SYSTEM_24
   12-Hour Time	24-Hour Time

3. Firmware upgrade

   The chip firmware upgrade method of each platform is different, and the upgrade method of each platform is as follows.

• Nordic/Goodix

• Huntersun

  The upgrade mode of Huntersun watch is different from the normal mode. It has a separate broadcast name and Mac address, and the Mac address is called back through CRPDeviceDfuAddressCallback. Before the upgrade, you need to query the Mac address of the firmware upgrade mode of the watch. You can save this Mac address and re-upgrade after the upgrade fails.

  xxxxxxxxxxbleConnection.queryHsDfuAddress(CRPDeviceDfuAddressCallback);

  After the watch enters the firmware upgrade mode, it will disconnect the Bluetooth connection from the normal mode, and initiate a firmware upgrade after the Bluetooth connection is disconnected. After the watch enters the firmware upgrade mode, it is not allowed to initiate a normal Bluetooth connection, which will cause the firmware upgrade to fail.

  xxxxxxxxxxbleConnection.enableHsDfu();

  The upgrade progress is called back through CRPBleFirmwareUpgradeListener. After the upgrade is successful, the watch will restart and return to the normal mode; after the upgrade fails, the firmware upgrade can be restarted.

  xxxxxxxxxxHsDfuController hsDfuController = new HsDfuController();hsDfuController.setUpgradeListener(CRPBleFirmwareUpgradeListener);hsDfuController.setAddress(address);hsDfuController.start();

  After the upgrade succeeds or fails, this interface can be called to exit the firmware upgrade process.
