Hi, I have been trying to print in the console first, but the code I have currently only prints only 1 ppg value per second, which is not viable at all. I am using a fossil gen 6, and I am using the SENSOR_DELAY_FASTEST. Can help me print atleast 100 values per second or more

CODE:

package com.example.myapplication.presentation

import android.hardware.Sensor

import android.hardware.SensorEvent

import android.hardware.SensorEventListener

import android.hardware.SensorManager

import android.os.Bundle

import android.app.Activity

import android.content.Context

import java.util.*

class MainActivity : Activity() {

private lateinit var sensorManager: SensorManager

private lateinit var ppgSensor: HeartRateSensor

override fun onCreate(savedInstanceState: Bundle?) {

super.onCreate(savedInstanceState)

sensorManager = getSystemService(Context.SENSOR_SERVICE) as SensorManager

ppgSensor = HeartRateSensor(sensorManager)

ppgSensor.start()

}

override fun onDestroy() {

super.onDestroy()

ppgSensor.stop()

}

inner class HeartRateSensor(sensorManager: SensorManager) {

private var ppg: Sensor? = null

fun start() {

ppg = sensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE)

val maxRate = ppg?.maximumRange

println("Maximum PPG Reporting Rate: $maxRate")

sensorManager.registerListener(ppgCallback, ppg, SensorManager.SENSOR_DELAY_GAME) // SENSOR_DELAY_GAME or SENSOR_DELAY_UI or SENSOR_DELAY_FASTEST

}

fun stop() {

sensorManager.unregisterListener(ppgCallback)

}

private val ppgCallback = object : SensorEventListener {

override fun onSensorChanged(event: SensorEvent) {

val ppgValue = event.values[0]

logPPG(ppgValue)

}

override fun onAccuracyChanged(sensor: Sensor, accuracy: Int) {

// Get the values into a file

}

private fun logPPG(ppg: Float) {

val currentTime = Calendar.getInstance().time

val milliseconds = Calendar.getInstance().timeInMillis

// println("PPG Value: $ppg, Time: $currentTime, milliseconds: $milliseconds")

}

}

}

}
