bricknil-bleak 0.3.1

Installation

$ pip install bleak

Features

• Supports Windows 10, version 16299 (Fall Creators Update)

• Supports Linux distributions with BlueZ >= 5.43

• Plans on macOS support via Core Bluetooth API (see develop branch for progress)

Bleak supports reading, writing and getting notifications from GATT servers, as well as a function for discovering BLE devices.

Usage

To discover Bluetooth devices that can be connected to:

import asyncio
from bleak import discover

async def run():
    devices = await discover()
    for d in devices:
        print(d)

loop = asyncio.get_event_loop()
loop.run_until_complete(run())

Connect to a Bluetooth device and read its model number:

import asyncio
from bleak import BleakClient

address = "24:71:89:cc:09:05"
MODEL_NBR_UUID = "00002a24-0000-1000-8000-00805f9b34fb"

async def run(address, loop):
    async with BleakClient(address, loop=loop) as client:
        model_number = await client.read_gatt_char(MODEL_NBR_UUID)
        print("Model Number: {0}".format("".join(map(chr, model_number))))

loop = asyncio.get_event_loop()
loop.run_until_complete(run(address, loop))
