How to detect acceleration events with BlueSTSDK Android App?

Hi at all,

I am using the BlueSTSDK Android App to receive data transfered via Bluetooth Low Energy by the STEVAL-STLKT01V1 SensorTile.

I would like to detect accelerometer events as orientations, single taps, etc, with this app but I don't undestand how to unblock the 'Accelerometer Events' in the 'Feature list' activity.

In the FeatureAccelerationEvent.java file is reported that I must call the following functions:

- detectEvent()

- onDetectableEventChange()

but I don't know where and how I must call this functions.

Is there anybody that can help me?

Best regards,

Tommaso

Hi Tommaso,

To receive an acceleration event you have to:

- enable the Feature notification (using the enableNotificaiton Node method)

- register a feature listener for the FeatureAccelerationEvent instance

- enable the event detection using the enableEvent(eventType, true) method. 

When the board enables the detection of the event you will receive a callback on the  

onDetectableEventChange method.

To stop detecting an event you have to  use

enableEvent(eventType, false)

 

If you need more examples you can look to the

  or the
