Check driver version by Erimelowo · Pull Request #1618 · SlimeVR/SlimeVR-Server
This will check the slimevr driver protocol version, starting at 1 and either display, for example:
[ProtobufBridge] Driver protocol version matches the server protocol version: 1
or
[ProtobufBridge] Driver protocol version (2) doesn't match the server protocol version (1)
in console.
It can also be used in code to make sure the user has a matching driver for new features.
