pip install "friend-lite-sdk[deepgram,wyoming]"  # Both

Features

• BLE Audio Streaming — Connect to OMI/Friend Lite devices and stream Opus-encoded audio
• Button Events — Subscribe to single tap, double tap, long press events
• Haptic Control — Trigger haptic feedback patterns on supported devices
• WiFi Sync — Configure and trigger WiFi-based audio sync
• Storage Access — Read stored audio from device storage

Quick Start

import asyncio
from friend_lite import OmiConnection, ButtonState, parse_button_event

async def main():
    async with OmiConnection("AA:BB:CC:DD:EE:FF") as conn:
        # Stream audio
        await conn.subscribe_audio(lambda _handle, data: print(len(data), "bytes"))

        # Listen for button events
        await conn.subscribe_button(
            lambda _handle, data: print("Button:", parse_button_event(data))
        )

        await conn.wait_until_disconnected()

asyncio.run(main())

Device Discovery

import asyncio
from friend_lite import print_devices

asyncio.run(print_devices())
