Custom Bluetooth input sensor / controller

Hi everyone,

I'm developing project on Oculus Quest 2 with Hand Tracking in Unity.

I need to provide additional input value from external sensor.

Input value is just user's pressure on the sensor: may be float with 0.0 - 1.0 values. No movement, rotation or anything else. One sensor and one float value.

Now I'm making it long way around using sensor with Arduino + WiFi and local server pairing but need something "less delayed".

Have You ever tried to make Your custom Bluetooth controller / sensor to connect to Oculus Quest 2 and use it in Unity?
