I am using python 3.12 with bleak to try and communicate with a BLE rubik’s cube. Currently all I can do is pull the model id with this code:

import asyncio
from bleak import BleakClient

address = "E0:F4:65:59:81:EF"
MODEL_NBR_UUID = "00002a00-0000-1000-8000-00805f9b34fb"

async def main(address):
    client = BleakClient(address)
    try:
        await client.connect()
        model_number = await client.read_gatt_char(MODEL_NBR_UUID)
        print("Model Number: {0}".format("".join(map(chr, model_number))))

    except Exception as e:
        print(e)
    finally:
        await client.disconnect()

asyncio.run(main(address))

This Works as Expected and prints the following out Model Number: GoCube_EF8159_1 but when I try to read or start notifications on other characteristics nothing seems to happen. I added notification code like this:

import asyncio
from bleak import BleakClient

address = "E0:F4:65:59:81:EF"
MODEL_NBR_UUID = "00002a00-0000-1000-8000-00805f9b34fb"


async def cube_update(sender, data):
    print(f"{sender}: {data}")
async def main(address):
    client = BleakClient(address)
    try:
        await client.connect()
        model_number = await client.read_gatt_char(MODEL_NBR_UUID)
        print("Model Number: {0}".format("".join(map(chr, model_number))))

        await client.start_notify("6e400003-b5a3-f393-e0a9-e50e24dcca9e", cube_update)

    except Exception as e:
        print(e)
    finally:
        await client.disconnect()

asyncio.run(main(address))

Even when I added this code, the output is the same and it finishes executing almost immediately after printing out the name. I do not believe I am using the wrong characteristic and more information about the cube’s specific protocol can be found on this gituhb page. Additionally, I tested the notifications using a debugging app on my phone it notified my phone just fine. My main goal is to get the move notation every time the cube spins which I will eventually use to come up with a solution to the cube.
