To discover Bluetooth devices that can be connected to:

import asyncio
from bleak import BleakScanner

async def main():
    devices = await BleakScanner.discover()
    for d in devices:
        print(d)

asyncio.run(main())

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 = "2A24"

async def main(address):
    async with BleakClient(address) as client:
        model_number = await client.read_gatt_char(MODEL_NBR_UUID)
        print(f"Model Number: {model_number.decode()}")

asyncio.run(main(address))
