Description

Cant connect to device

What I Did

import asyncio
import binascii
import uuid
from bleak import BleakClient, BleakScanner
from bleak.exc import BleakError

MAC = "00:A0:50:82:75:CA"
NAME_CHARACTERISTIC = '00002A00-0000-1000-8000-00805F9B34FB'
GENERAL_SERVICE = '00001801-0000-1000-8000-00805f9b34fb'

async def main(ble_address: str):
    device = await BleakScanner.find_device_by_address(ble_address, timeout=20.0)
    async with BleakClient(device) as client:
        services = await client.get_services()
        print("Services:")
        for service in services:
            print(service)
        value = bytes(await client.read_gatt_char(uuid.UUID(NAME_CHARACTERISTIC))).decode('utf-8')
        print(value)

asyncio.run(main(MAC))

The stack-trace is:

Traceback (most recent call last):

Same code at the native Linux works correctly

When my RTL8761BU based ZEXMTE BT-505 gets overloaded I get this error.

I replaced it with a Feasycom FSC-BP119 which is CSR8510A10 and seems to handle the bluetooth density quite a bit better.
