Android Tablet with LED ring light

[bayensf]

Dear all,

Recently recieved my tablet with wallmount. It has RGB LED light on the 4 edges.
Does anyone know how to send a command to the tablet so the light will go on/off?
And how the command looks like when I want to send RED, GREEN or WHITE light?

Device is WA1383T also known RK3399 from ELC

Many thanks for your support.

regards,
