# MinewSensorKit Instruction document

This SDK only supports the Bluetooth sensor devices from Minew. The SDK helps developers to handle everything between the phone and the sensor, including: scanning the device, broadcasting data, connecting to the device, writing data to the device, receiving data from the device, etc.

# Preliminary work

Overall framework: IndustrySensorBleManager is the device management class, which is always a single instance when the app is running. IndustrialHtSensor is the device instance class, this suite generates an instance for each device, which is used after scanning and connecting, and contains device broadcast data inside, which will be updated during scanning as the device keeps broadcasting.

IndustrySensorBleManager：Device management class that scans the surrounding ESL devices and can connect them, verify them, etc.；

IndustrialHtSensor：Example of an industrial temperature and humidity sensor device acquired during scanning, inherited from SensorModule；

# Import to project

  1. Development Environment

    The minimum sdk support is Android 5.0, corresponding to API Level 21. set minSdkVersion to 21 or above in build.gradle of the module.

    android {

    defaultConfig {
        applicationId "com.xxx.xxx"
        minSdkVersion 21
    }
}

  2. Add industry_ht_sensor_sdk.jar to the module's libs folder and add the following statement to the build.gradle of the module (add the dependency directly).

    implementation files('libs/industry_ht_sensor_sdk.jar')
implementation files('libs/sensor_sdk_base.jar')
implementation 'org.lucee:bcprov-jdk15on:1.52.0'

    Or right-click the jar file and select Add as Library to add it to the current module.

  3. The following permissions are required in AndroidManifest.xml, and if targetSdkVersion is greater than 23, you need to do permission management to get the permissions.

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

# Use

The sdk is divided into three phases: scanning, connecting, and reading and writing.

# Scanning section

# Start scanning

For Android 6.0 or above, you need to apply for location permission and turn on the location switch before you can perform BLE scanning.

To turn on Bluetooth scanning, you need to turn on Bluetooth first, if you go to scan without turning on Bluetooth, the app will flash back. BLETool.isBluetoothTurnOn can be used to determine if Bluetooth is turned on. If not open, you can call BLETool.setBluetoothTurnOn to open it.

IndustrySensorBleManager manager = 	IndustrySensorBleManager.getInstance(context);
if(BLETool.isBluetoothTurnOn(context)){
    manager.startScan(context,new OnScanSensorResultListener() {
        @Override
        public void onScanResult(List<IndustrialHtSensor> scanBadgeList) {
            //scan result
        }
        @Override
        public void onStopScan(List<IndustrialHtSensor> scanBadgeList) {
            //stop scan result
        }
    });
    //Set scan duration 5 minutes, sdk default scan duration 5 minutes
        manager.startScan(context,5*60*1000，new OnScanSensorResultListener() {
        @Override
        public void onScanResult(List<IndustrialHtSensor> scanBadgeList) {
            //scan result
        }
        @Override
        public void onStopScan(List<IndustrialHtSensor> scanBadgeList) {
            //stop scan result
        }
    });
}

The sdk does not handle the length of the Bluetooth scan internally, but the scan is a power hungry operation, the sdk stops scanning in 5 minutes by default, if you still need to continue scanning, you can provide a timer or refresh and other operations to continue to call the scan method to continue scanning the device.

# Retrieve data

During the scan, the APP is able to get a part of the current data of the device through the sdk. The industrial temperature and humidity data of the device is obtained through IndustrialHtSensor as shown below, which is stored in the broadcast frame object.

The sdk provides SensorModule as the base class of IndustrialHtSensor to store the public data of the sensor device as shown in the following table.

Name Type Description
macAddress String device mac
name String Device name, customizable. The initialized name of the industrial temperature and humidity sensor is "MST01".
rssi int Signal strength

The SensorModule also keeps a Map, which is used internally to store the device broadcast data frames it acquires during a scan, and can be retrieved as follows

DeviceStaticInfoFrame deviceInforFrame = (DeviceStaticInfoFrame)module.getMinewFrame(HtFrameType.DEVICE_STATIC_INFO_FRAME);
IndustrialHtFrame industrialHtFrame = (IndustrialHtFrame) module.getMinewFrame(HtFrameType.INDUSTRIAL_HT_FRAME);
if (deviceInforFrame != null) {
    //Device mac address
    String macAddress = deviceInforFrame.getMacAddress();
    //Percentage of power
    int battery = deviceInforFrame.getBattery();
    //firmware version
    String firmwareVersion = deviceInforFrame.getFirmwareVersion();
}

if (industrialHtFrame != null) {
    //Temperature and humidity sensor current temperature
    float temperature = industrialHtFrame.getTemperature();
    //Temperature and humidity sensor current humidity
    float humidity = industrialHtFrame.getHumidity();
    //Sensor type 0: Temperature and humidity, 1: Single temperature
    int type = industrialHtFrame.getType();
    //Temperature units are 0 for Celsius and 1 for Fahrenheit
    int type = industrialHtFrame.getTemperatureUnit();
}

There are 2 types of broadcast frames for industrial temperature and humidity equipment.

  1. Device static information frame

    • DeviceStaticInfoFrame

      Name Type Description
      frameVersion int device type
      firmwareVersion String Firmware Version
      batteryLevel int Battery Level Percentage
      macAddress String firmware mac
      peripheralSupportInfo PeripheralSupportInfo Description of peripheral support

  2. Industrial temperature and humidity frames

    • IndustrialHtFrame

      Name Type Description
      frameVersion int device type
      tempHumiVersion int MST01 Temperature and humidity frame version
      type int Sensor type. 0: Temperature and humidity, 1: Single temperature
      sensorStatus DeviceExceptionEnum Device status, such as normal, sensor abnormal, etc.
      temperatureUnit int Temperature units : 0 : Celsius , 1 : Fahrenheit
      temperature float Sensor current temperature
      humidity float Sensor current humidity
      isMark float Marked or unmarked, 1: marked, 0: unmarked
      deviceName String Device Name

# Connections

It is usually necessary to stop scanning before connecting. sdk provides methods to connect and disconnect.

//Stop scanning
manager.stopScan(context);
//Setting the device secret key
String key;
manager.setSecretKey(key);
//Connection, module for the device to be connected
IndustrialHtSensor module;
manager.connect(context,module);
//Disconnect. macAddress is the device mac
manager.disConnect(macAddress);

Note: Before connecting the device, please confirm whether the device is scanned, if no device broadcast is scanned and the connection method is called, the connection will fail.

After calling connect(), there will be a status listener in sdk for the connection process.

//Setting the listener
manager.setOnConnStateListener(new OnConnStateListener() {
    
    /*
     * Status callbacks during connection
     *
     * @param macAddress      device mac
     * @param connectionState status
     */
    @Override
    public void onUpdateConnState(String address, MSensorConnectionState state) {
        switch (state) {
            case Disconnect:
				//Connection failure or device disconnection will be called back, active disconnection will not call back the 					//status
                break;
            case Connecting:
				//This state will be called back after calling connect()
                break;
            case Connected:
                //The initial connection was successful, as a transition phase, but not really successful at this point
                break;
            case ConnectComplete:
				//Connection is complete, the device is now ready for read and write operations
                break;
            default:
                break;
        }
    }
});

During the connection process, sdk will return multiple connection states to the app, which the app needs to handle properly.

  • MSensorConnectionState.Connecting, MSensorConnectionState.Connected: Connecting the device in, do not do time-consuming operations in this state, because at this time in the connected device discovery service, and send authentication data, etc.
  • MSensorConnectionState.ConnectComplete: The sensor device is successfully connected at this point, and can perform read and write operations, such as configuring broadcast parameters, sensor configuration, reading historical data, etc.
  • Disconnect: The callback will be made if the connection fails or the device is disconnected. If the APP actively calls manager.disConnect(macAddress); it will not call back this state.

# Reading and writing

The read and write APIs are as follows.

    /**
