Description

**Describe the problem you have/What new integration you would like**

I have a fingerprint sensor HLK-FPM383C (also labeled in some websites as Grow R557), that is working good with fingerprint grow integration. However the aura LED control, even it prints command set succesful, does not light the LED ring.

**Please describe your use case for this integration and alternatives you've tried:**

The LED ring of this sensor is not working.

**Additional context**

I attach the documentation I got from the seller, even if I don't know if this is the correct one.

Research direction

Start by reading the attached FPM383C manual and inspecting the existing fingerprint grow integration referenced in the issue. Determine the supported LED-ring control command and how the current integration reports success without lighting the ring. Done means the HLK-FPM383C or GROW R557 LED ring responds correctly to the requested control.
