There's some code specifically for Node.js in this tutorial that might help you out: http://www.espruino.com/Puck.js+Advertising
There are other ways of doing it (like with a connection) but this way is nice and easy and doesn't require any pairing or connection. When using
NRF.setAdvertisingon the Puck you can choose a low interval (as low as 7.5ms) which would get the latency down, but that will hurt your battery life so you might want to think about having the Puck lower the interval down to 300ms or so after an hour of inactivity.Hope that helps!
