What I Did

  1. get a linux borard (Sipeed LicheeRV Nano) https://www.alibaba.com/product-detail/Sipeed-LicheeRV-Nano-Litchi-Pi-SG2002_1601059587927.html?spm=a2700.galleryofferlist.normal_offer.d_title.59f213a0npUk9B

wiki: https://wiki.sipeed.com/maixpy/en/index.html

  1. pip install bleak

  2. create hci with /dev/ttyS1 and up it. 29054-4eb7ba9fc3714363ae213f91209c0b5f 29054-11ea08af61344ce79e332ec016034dcf

  3. run above-mentioned test code

import asyncio
from bleak import BleakScanner, BleakClient

async def main():
    device = await BleakScanner.find_device_by_address(
            'F6:0C:C0:F5:66:52'
        )

    print(device)

    if device is None:
        print('not found device')
        return

    async with BleakClient(device) as client:
        print('connected')
        print(client)

asyncio.run(main())
