Как подключиться к устройству Bluetooth BTLE на Raspberry Pi? ⇐ Python

[Anonymous]

Я пытаюсь подключиться к устройству BTLE с Raspberry Pi, но постоянно терпит неудачу. Можете ли вы помочь мне улучшить это?
Устройство находится на расстоянии примерно 3–4 метров от Raspberry Pi Model B Rev 1.2. Используя простой скрипт ниже:

import asyncio
from bleak import BleakClient
from loguru import logger

async def just_connect(mac):
async with BleakClient(mac) as client:
connected = await client.is_connected()

async def connect_handler(mac,try_):
try:
await asyncio.wait_for(just_connect(mac), timeout)
logger.info(f"try {try_} succeeded")

except Exception as e:
logger.info(f"try {try_} failed due to {type(e).__name__}: {e}")

mac = "C5:5A:42:A4:3C:80"
tries = 10
timeout = 12
for try_ in range(tries):
asyncio.run(connect_handler(mac,try_))

Вывод журнала гласит:

Что я пробовал раньше:

• перепроверил код и Mac, это (иногда) работает из Windows машина
• перезапустила устройство BTLE
