BLE cannot find puck.js

I have two puck.js, received a few months ago. I had paired both in IDE and everything worked. Then they went in the drawer somewhere.

I got them out today. Upgraded both to v2.05. One paired with the IDE and works well. The other does not seem to show up at all during BLE Select. I have hard reset it a few times. The self-test seems to pass. It seems functional, just does not connect/pair.

How do we forget a Puck that was paired before but does not now show up?

Is it possible that a phone/PC/etc is still 'paired' to the Puck so is auto-connecting to it?

You could also try powering up the Puck while holding the button - that'll clear out any saved code and Bluetooth Pairing info that there might have been.

I have made sure that other bluetooth devices are no connected to it.

I've reflashed the Puck with v2.05 using nRFTool. I also powered up while holding the button (until beyond the 5 red blinks).

On the desktop, I reset its bluetooth module so that it has no memories of prior pairings (I had to re-pair my keyboard and mousepad).

In this fresh start, the other Puck appears quickly in web IDE and is re-paired.

The web IDE still cannot seem to find this Puck during 're-scan'.

I used another computer and managed to see two entries (9663). I did not pair then.

I returned to the first computer and was able to find the Puck and pair with it.

Solved. Thanks! But why the two entries?

Is it possible you'd tried using NRF.setAddress at some point in the past to set custom Mac address?

Not as far as I know. Both Pucks now behave well. Thanks.
