the use-case is not the same. The linked query talks about configurating a Teltonika RUTX11 to use Teltonika Blue Puck Bluetooth Sensors.
It was explained in other querries that several Teltonika devices are supported via Bluetooth.
But as far as I understand, non-Telfonica devices are not supported on the web interface.
For our project, we need to connect to a specific set of non-Telfonica devices via Bluetooth and forward the data via MQTT.
Example:
It is not important what kind of device and data. As an example we could also use a regular Bluetooth mouse. We would like to connect to the mouse via Bluetooth LE. Read the mouse related data and forward them via MQTT.
