How to connect to a Bluetooth BTLE device on Raspberry Pi?

I try to connect to a BTLE device from a Raspberry Pi, but it fails consistently. Can you help me improve this?

The device is about 3-4 meters away in plain sight from the Raspberry Pi Model B Rev 1.2. Using the simple script below:

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_))

The logging output reads:
