how to prevent auto-sleep?

[ericries]

I've been building an app using this amazing data (thank you all!). I am able to periodically affect the joycon state, including with rumble and the LEDs lighting up. But I find that after about an hour the joycons will turn themselves off and I have to restart and reconnect them manually.

Does anyone know how to prevent or disable this behavior? or if not, what is it that the joycon uses to determine if it's idle?

I would like to know the answer to this too.
