[Solved] LEDs stay off on nodejs

Got my Matrix voice, installed as described on raspberry pi 3 with the help of my dad. Hardware demos are working nicely, leds are working. But when starting the node HelloWorld demo, it says that it started the app, but the leds are not doing what they are supposed to do, precisely doing nothing at all.

Hi @AstroVoice111. Which programming layer did you install on your Matrix device? LEDs for MATRIX OS (MOS) do not currently work on MATRIX Voice. We’ve recently changed how we handle LEDs in MATRIX CORE, the layer used to build MOS, and the changes have yet to be implemented in MOS. Currently, MOS is under maintenance as we add more features to MATRIX CORE.

For now, I’d suggest using MATRIX CORE. The getting started section will explain everything you’ll need to understand and work with this layer.

Let us know if you have any more questions or suggestions.
