Hey all. I (or my kids) have misplaced a Puck, it is still broadcasting and I'm seeing it on my PixlJs. Has anyone experimented with sending some code over to theirs so it can be found via whatever electronics work best?

Thanks!

you can check the RSSI value when scanning to guess the distance, nrfConnect app on phone can show it. Too bad there is no speaker but there are LEDs and light sensor so you can blink it in the dark to possibly see it or you can use torch and read the light sensor to see if the light is hitting it.

Did you have any luck? Usually looking at the RSSI (eg via NRF Connect app which can show a graph) might be good enough to get you in the same rough area as it.

For more general losses I though I should mention there is openhaystack which can be uploaded at https://espruino.github.io/EspruinoApps/?id=openhaystack and will turn your Puck into an Apple AirTag. There's a Bangle.js app too. You'll still have a similar issue finding it nearby, but at least it would be trackable over the world using any iPhone in range

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.
