Android nRF Mesh UUID generating, searching

[matej1410]

Hello.

My question concerns UUID.

Exactly where does it come from?

     * Mesh provisioning data in characteristic UUID
     */
    private final static UUID MESH_PROVISIONING_DATA_IN = UUID.fromString("00002ADB-0000-1000-8000-00805F9B34FB");
    /**
     * Mesh provisioning data out characteristic UUID
     */
    private final static UUID MESH_PROVISIONING_DATA_OUT = UUID.fromString("00002ADC-0000-1000-8000-00805F9B34FB");

    /**
     * Mesh provisioning service UUID
     */
    public final static UUID MESH_PROXY_UUID = UUID.fromString("00001828-0000-1000-8000-00805F9B34FB");

    /**
     * Mesh provisioning data in characteristic UUID
     */
    private final static UUID MESH_PROXY_DATA_IN = UUID.fromString("00002ADD-0000-1000-8000-00805F9B34FB");

    /**
     * Mesh provisioning data out characteristic UUID
     */
    private final static UUID MESH_PROXY_DATA_OUT = UUID.fromString("00002ADE-0000-1000-8000-00805F9B34FB");

Can I generate this UUID for my own application (https://www.uuidgenerator.net/) or maybe it is constant and unalterable and everyone should always use:

MESH_PROVISIONING_DATA_IN = UUID.fromString("00002ADB-0000-1000-8000-00805F9B34FB"); in case of attribution string to MESH_PROVISIONING_DATA_IN and any other UUID can not be used?

Hi!

My question concerns UUID.

 Which UUID are you referring to here?

Best regards

Basicly each from this snippet. 

For example first one:

private final static UUID MESH_PROVISIONING_DATA_IN = UUID.fromString("00002ADB-0000-1000-8000-00805F9B34FB");
