Key/value settings

const current = await device.brain.getValue("example.key");
if (current.isErr()) throw current.error;

const updated = await device.brain.setValue("example.key", "value");
if (updated.isErr()) throw updated.error;

console.log({ current: current.value });

getValue() returns Ok(undefined) when the brain doesn’t send a usable reply. setValue() returns Ok(undefined) when the brain acknowledges the write. Use .isErr() and .error to handle connection or protocol failures.

These are system-level values. Only write keys documented for the target VEXos version.
