Puck.js whitelisting failure

Hello,

I've been unsuccessfully trying to whitelist connections to my Puck.js (firmware 2.01) the last few weeks, so I figured it was time to throw a lifeline in hopes someone can help identify what I am doing wrong. I've tried with my Samsung S9, Samsung S8+, and Windows Surface Pro using the following code snippet as a guide:

NRF.on('connect',function(addr) {
  if (addr!="69:2d:94:d0:9d:97 public")
    NRF.disconnect();
});

I've double checked the MAC addresses several times, and have tried string combinations of just the mac address, and both "public" and "random" extensions as described here:(https://www.espruino.com/Puck.js+Securit­y).

The only result I get is refusal of all connections to Puck.js.

Any help would be much appreciated.

Thank you.
