Bluetooth Led fails to normalize_uuid_str containing 'None'

[notexpected]

The problem

When attempting to configure an auto-discovered bluetooth led, it fails with:

ValueError: invalid literal for int() with base 16: '0000None00001000800000805f9b34fb'`

Seems like None is being passed unexpectedly here.

Same with MELK-OA21 14 (BE:16:58:00:29:14)

Experiencing the same problem with MELK-OC10 on Home Assistant Core 2024.7.1 and 2024.7.2

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

That seems like the device is producing an invalid UUID, but it could be improved in bleak

Hello, i have the same problem with my HappyLighting/Triones LED Spotlight:

Any updates for the problem? Thx!!

Hi, i purchased the device on Amazon but the listing changed so it's not the same model anymore... anyway here is the link:

https://amzn.eu/d/1qDc1Lj

About the model number there is none outside or inside the product, i took some photos of the SOCs on the (what is seems) BLE radio board:

Board Name: TGDLYMK-6 BLE Controller: ST17H26 CA2045 CM8A0V.1 EEPROM: PT24C02 F2019

I'm using the integrated Bluetooth Adapter on the Raspberry Pi 3 B+ where my HAS instance is running:

Adapter: bcm43438-bt

Device name shown by Home Assistant:

Triones-FFFF385A580B (FF:FF:38:5A:58:0B)

[bdraco]

Thanks. If you can find the same model available for shipping to the US, I'll purchase it and see if I can fix the problem.

[pyerix]

All the listings from Amazon ( .com and .it ) seem to be gone for this specific model, i fond the same spotlight from Ebay, it should ship to the US.

Great. Ordered!

I have similar problem with led lamp (https://www.action.com/pl-pl/p/3207285/wielokolorowa-lampa-dotykowa/). '0000None00001000800000805f9b34fb' is one of UUIDs (screenshot).

homeassistant  |   File "/usr/local/lib/python3.13/uuid.py", line 182, in __init__
homeassistant  |     int = int_(hex, 16)
homeassistant  | ValueError: invalid literal for int() with base 16: '0000None00001000800000805f9b34fb'

EDIT: PDF (https://adiy.in/wp-content/uploads/2024/02/ADIY-HLK-B50-Bluetooth-Module_Datasheet.pdf) mentions this UUID 0000fff100001000800000805f9b34fb.

[Ermodo]

Adding information on my devices to the list. Maybe there is something in common :)

Link to the lamp on amazon: https://a.co/d/gGZgJHk There are lots of different companies building it under different names. The product number SPL-FLL001 is the same.

Displayname in Home Assistant: MELK-OC10 F1 (4DF1) LED BLE Address: BE:16:C7:00:4D:F1 My current Bluetooth-Chipset of Home Assistant is a Realtek RTL8822CE (but the integrated Raspberry Pi 4 Adapter reports the same problem).

The service UUID seems to be the same as j0zzy's. Please let me know, if I can provide additional information which might help you :)

EDIT: My devices can be controlled trough an app, which makes a local ble connection to the devices. https://play.google.com/store/apps/details?id=wl.smartled.duoco.rgb I took a quick look inside with https://github.com/Konloch/bytecode-viewer From what I can tell, the class com.easylink.colorful.service.BluetoothLEService does all the heavy lifting. I haven't looked into details, but it seems to usually sends 9 bytes to the device which encode the operation and the value to set. It looks for services with the UUID 0000fff0-0000-1000-8000-00805f9b34fb and their characteristics 0000fff3-0000-1000-8000-00805f9b34fb and sends the data there.

[notexpected]

I did a bit of logic tracing and I documented an issue on an underlying library: https://github.com/Bluetooth-Devices/led-ble/issues/35

Basically it seems that the bluetooth services are not being resolved (code) and that is causing the self._read_char to be NONE when normalizing the UUID.
