The Mentra Bluetooth SDK Starter Kit contains complete example apps for Android, iOS, and React Native / Expo. 
git clone https://github.com/Mentra-Community/Mentra-Bluetooth-SDK-Starter-Kit.git
cd Mentra-Bluetooth-SDK-Starter-Kit

​
What The Examples Demonstrate

  • Scanning for supported Mentra glasses, connecting, disconnecting, and reconnecting to a saved/default device.
  • Reading typed glasses and Bluetooth status snapshots.
  • Displaying text, clearing the display, and opening the dashboard where supported.
  • Handling button, touch, swipe, head-up, battery, Wi-Fi, hotspot, stream, photo, audio, and SDK log events.
  • Controlling model-supported features such as dashboard position, head-up angle, gallery-button behavior, button photo/video settings, speaker playback, RGB LED patterns, Wi-Fi, hotspot, microphone, camera, and streaming.
  • Running the default glasses-to-phone photo and streaming demos, plus optional cloud-server demos for external upload and streaming endpoints.

​
Android

cd examples/android
./gradlew installDebug
The Android example is a Kotlin / Jetpack Compose app. It installs the SDK as com.mentra:bluetooth-sdk.

​
iOS

cd examples/ios
pod install
open MentraExample.xcworkspace
The iOS example is a SwiftUI app. It installs the SDK as the MentraBluetoothSDK CocoaPod.

​
React Native / Expo

cd examples/react-native
bun install
bunx expo prebuild
bunx expo run:ios
# or
bun run android:dev
The React Native example installs the SDK as @mentra/bluetooth-sdk and demonstrates the same Device, Camera, Stream, System, and Console flows as the native examples.

​
Optional Local Photo And Streaming Helper

The Camera and Stream screens default to a glasses-to-phone flow where the example app starts a receiver on the phone and sends the glasses output there. You do not need this helper for that default path. Use this helper only when you turn on Use cloud server in the example app and want to test an external endpoint without deploying your own photo webhook or streaming server. Production apps can use any reachable HTTPS upload endpoint and any reachable RTMP, SRT, or WHIP ingest URL. From the repo root: 
python3 examples/local-demo-cloud/server.py
After enabling Use cloud server, paste the printed LAN /upload URL into the Camera screen, or paste the printed RTMP, SRT, or WHIP publish URL into the Stream screen. If Docker is not installed or not running, the helper starts the photo webhook and skips streaming with a warning.
Do not use localhost in the app. The glasses, phone, and computer must be on a network where the glasses can reach the printed LAN address.

​
Local SDK Development

Package-manager installs are the normal SDK path. Use local overrides only when testing SDK source changes:
  • Android: publish com.mentra:bluetooth-sdk and its companion artifacts to Maven local, then build the example with mavenLocal() enabled.
  • iOS: set MENTRA_BLUETOOTH_SDK_LOCAL_PATH to a local SDK checkout before pod install.
  • React Native: install a local @mentra/bluetooth-sdk package path and set MENTRA_BLUETOOTH_SDK_PACKAGE_PATH so Metro and native builds resolve the same package.
Do not bake machine-specific paths into committed app config.
