LF/HF ​

The LF/HF value is sent as part of the final results.

The application can receive the LF/HF result by implementing VitalSignsListener:

Kotlin
override fun onFinalResults(results: VitalSignsResults) {
    runOnUiThread {
        (results.getResult(VitalSignTypes.LFHF) as? VitalSignLFHF)?.let { lfhf ->
            Log.i("VITAL SIGN", "LF/HF: ${lfhf.value}")
        }
    }
}
Java
@Override
public void onFinalResults(final VitalSignsResults results) {
    runOnUiThread(() -> {
        VitalSignLFHF lfhf = (VitalSignLFHF) results.getResult(VitalSignTypes.LFHF);
        if (lfhf != null) {
            Log.i("VITAL SIGN", "LF/HF: " + lfhf.getValue());
        }
    });
}

For general information about vital signs see the Vital Signs and Health Indicators Information Page.

For a list of supported vital signs per platform and measurement mode (face/finger) see the Supported Vital Signs Page.

Important

Note that vital signs are sent on a background thread. The application must switch to the UI thread in order to perform UI updates.
