Pixoo on HA-Core as Container / Connected but unable to send notifications

[MrSiO]

Hi. I'm using the Pixoo on my HA-CORE installation (Docker-Compose). Installation process went smoothly. Paired the Pixoo with success using the bluetoothctl command. Then installed the integration via HACS. Device was seen and added. In DEVELOPER TOOLS i'm trying to send notifications to: notify.divoom_pixoo But it always fails with message:

Failed to call service notify.divoom_pixoo. Unknown error

I went to my HA container logs and found this weird log:

2024-04-14T21:30:47.860157554Z 2024-04-14 17:45:47.859 WARNING (SyncWorker_21) [custom_components.divoom] Pixoo: connection lost (errno = 97).

Trying to reconnect for the 5 time.

I fond this link as a guide on how to format my notification... are they reliable? https://user-images.githubusercontent.com/1483070/151658085-fa078b40-20c5-48f3-b7ac-9a3ad887e0b0.png https://user-images.githubusercontent.com/1483070/151658110-40e7f945-edb2-4c5e-bd0c-3d3c920d8f45.png

Any ideas what might be wrong?
