Got incorrect speed.

[black1ava]

I am using @hariks789/react-native-background-geolocation and try to get speed when my phone is moving. But event though my phone I still got speed 1km/h, 2km/h... . The worst case is 26km/h.

Context

Expected Behavior

It should give the right speed. Like if device stays still, speed should be 0.

Actual Behavior

Possible Fix

Steps to Reproduce

async function initBackgroundGeolocation() {
BackgroundGeolocation.configure({
desiredAccuracy: BackgroundGeolocation.HIGH_ACCURACY,
stationaryRadius: 10,
distanceFilter: 10,
notificationTitle: 'Background tracking',
notificationText: 'ok',
debug: false,
startOnBoot: false,
stopOnTerminate: true,
locationProvider: BackgroundGeolocation.ACTIVITY_PROVIDER,
interval: 10000,
fastestInterval: 5000,
activitiesInterval: 10000,
stopOnStillActivity: false,
maxLocations: 1000,
url: '',
postTemplate: {
latitude: '@latitude',
longitude: '@longitude',
time: '@time',
bearing: '@bearing',
altitude: '@altitude',
accuracy: '@accuracy',
provider: '@Provider',
speed: '@speed',
},
startForeground: false,
});
}

const onLocation = location => {
console.log('location', location);
const odometer = convertSpeed(location.speed ?? 0); // speed * 18 / 5
setOdometer(odometer);
setIsMoving(odometer >= 15); // speed over 15km/h means moving
setLocation(location);
};

BackgroundGeolocation.on('location', onLocation);

Context

I tried to get speed so to know whether my device is moving. However I usually get incorrect value.
