I am currently writing an Android app in Android Studio for the Microsoft band that will record data from the GSR, HR, and Skin Temp.
I have the data for GSR and Skin Temp. currently reading on the application but the rate that it is updated is very slow, especially for the Skin Temp. I was wondering if there was a way to make these sensors send data more frequently because the data I have now has too long of intervals for the purpose I am using it for. Here is my MainPage.java file.
public class MainPage extends Activity {
private BandClient client = null;
TextView tvGSR;
TextView tvHeartRate;
TextView tvTemperature;
Button updateTest;
private BandGsrEventListener mGsrEventListener = new BandGsrEventListener() {
@Override
public void onBandGsrChanged(final BandGsrEvent event) {
if (event != null) {
appendGSRToUI(String.format("%d kΩ\n", event.getResistance()));
}
}
};
private BandSkinTemperatureEventListener tempEventListener = new BandSkinTemperatureEventListener() {
@Override
public void onBandSkinTemperatureChanged(final BandSkinTemperatureEvent event) {
if (event != null) {
appendTempToUI(String.format("%.2f ºF\n", event.getTemperature()*1.800 + 32.00));
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_page);
tvGSR = (TextView) findViewById(R.id.tvGSR);
tvTemperature = (TextView) findViewById(R.id.tvTemperature);
updateTest = (Button) findViewById(R.id.updateTest);
updateTest.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
tvGSR.setText("");
tvTemperature.setText("");
new GsrSubscriptionTask().execute(); // Put first (runs connection)
new TempSubscriptionTask().execute();
}
});
}
@Override
protected void onResume() {
super.onResume();
tvGSR.setText("");
tvTemperature.setText("");
}
@Override
protected void onPause() {
super.onPause();
if (client != null) {
try {
client.getSensorManager().unregisterGsrEventListener(mGsrEventListener);
client.getSensorManager().unregisterSkinTemperatureEventListener(tempEventListener);
} catch (BandIOException e) {
appendGSRToUI(e.getMessage());
appendTempToUI(e.getMessage());
}
}
}
@Override

if (client != null) {
try {
client.disconnect().await();

// Do nothing as this is happening during destroy
