puck.js - NRF.on('connect') - limit connection to one device

Hi,

It should be the device's Bluetooth MAC address.

If you haven't already seen it, this example of doing what you want might be helpful

Probably the best way to be sure is to just do:

var addrs = [];
NRF.on('connect',function(addr){ addrs.push(addr) });

Then disconnect, connect with the Pi, disconnect, connect with your PC and check what's in the addrs array?
