Synchroni SDK + kotlin demo

Brief

Synchroni SDK is the software development kit for developers to access OYMotion Synchroni products.

1. Permission

Application will obtain bluetooth permission by itself.

2. Import SDK

dependencies {
    implementation files('../sdk/sensor.jar')
}

import com.sensor.*

3. Initalize

request bluetooth permissions

//MainActivity.kt
PermissionX.init(this)
.permissions(permissions.asList())
.request { allGranted, grantedList, deniedList ->
    if (allGranted) {
        //setup scan delegate and scan
        SensorController.getInstance().startScan(6000);
        if (SensorController.getInstance().delegate == null){
            SensorController.getInstance().delegate =
                SensorController.SensorControllerDelegate { bleDevices ->
                }
        }
    }
}

4. Start scan

SensorController.getInstance().startScan(periodInMS);
//returns array of BLEDevice
SensorController.SensorControllerDelegate { bleDevices ->

    for (device in bleDevices) {
        if (!(device.name.startsWith("SYNC") || device.name.startsWith("OB"))) continue
        Log.d("DEMO", "found device: " + device.name);
        val sensor = SensorController.getInstance().getSensor(device.mac);
    }
}

5. Stop scan

    SensorController.getInstance().stopScan();

6. Connect device

SensorProfile.connect()

7. Disconnect

SensorProfile.disconnect()

8. Device status

8.1 Get device status

SensorProfile.deviceState;

Please send command in 'BLEState.ready'

public enum State {Disconnected, Connecting, Connected, Ready, Disconnecting, Invalid}

8.2 Get device status change

fun onStateChange(profile: SensorProfile, newState: BLEDevice.State) {
    Log.d("DEMO",
        "device : " + profile.device.name + " => " + newState.name
    )
}

9. DataNotify

9.1 init data notify

SensorProfile.initAll(PACKAGE_COUNT, timeoutInMS: TIMEOUT)

9.2 Start data transfer

For start data transfer, use void startDataNotification(Callback cb) to start. Process data in onSensorNotifyData.

SensorProfile.startDataNotification()

override fun onSensorNotifyData(profile: SensorProfile, rawData: SensorData) {
    Log.d("DEMO",
        profile.device.name + " got data type: " + rawData.dataType + " | " + rawData.channelSamples[0][0].sampleIndex
    )
    if (rawData.dataType == SensorData.NTF_EEG){

    }

}

data type：

typedef NS_ENUM(NSInteger, NotifyDataType)  {
    NTF_ACC_DATA,
    NTF_GYO_DATA,
    NTF_EEG,
    NTF_ECG,
    NTF_BRTH,
};

9.3 Stop data transfer

    sensor.stopDataNotification()
