react-native-headphone-motion

A react-native module for iOS CMHeadphoneMotionManager api, which you can use for getting the headphone(airpods) motion data, this api is only available for iOS 14+

Install

npm install react-native-headphone-motion
npx pod-install

Then you must add below config to Info.plist if you are going to get headphone motion data, or your app will be crashed by system:

<key>NSMotionUsageDescription</key>
<string>The description will be shown under the permission dialog</string>

API

isHeadphoneMotionAvailable

a boolean constant for checking if the system support this functionality

requestPermission() => Promise<AuthorizationStatus>

call this will trigger system permission dialog to request permission and return the permission status. Same with other permission strategy, the dialog only show at the first call, subsequent calls only return status.

getAuthorizationStatus() => Promise<AuthorizationStatus>

get the permission request status

startListenDeviceMotionUpdates() => Promise<void>

after calling this, onDeviceMotionUpdates event will be triggered continuously if the device was connected and onDeviceMotionUpdatesError would be triggered if error occurred

startDeviceMotionUpdates() => Promise<void>

after calling this, no onDeviceMotionUpdates or onDeviceMotionUpdatesError would be triggered, you need to manually call getLatestDeviceMotion() to get the latest motion data

stopDeviceMotionUpdates() => Promise<void>

after calling this, onHeadphoneDisconnected event would be triggered (the system automatically disconnect your headphone from your app if you stopped getting motion updates), and getLatestDeviceMotion() will always return empty data

isDeviceMotionActive() => Promise<boolean>

check if you are in active status of getting motion data

getLatestDeviceMotion() => Promise<HeadphoneMotionData | null>

get the latest motion data, normally used with startDeviceMotionUpdates, return null if you did not call startXxUpdates

onDeviceMotionUpdates((data: HeadphoneMotionData) => void) => EmitterSubscription

a listener called after you called startListenDeviceMotionUpdates

onDeviceMotionUpdatesError((error: {text: string}) => void) => EmitterSubscription

a listener called after you called startListenDeviceMotionUpdates

onHeadphoneConnected(() => void) => EmitterSubscription

a listener called when you called startXxUpdates and headphone is in connected

onHeadphoneDisconnected(() => void) => EmitterSubscription

a listener called when you called stopDeviceMotionUpdates and headphone is in connected
