Is it possible to store events (button press) with a puck that are retrievable later when a bluetooth device is connected?

Yes, absolutely. You might find this helpful: http://www.espruino.com/Data+Collection

It shows you how to store data and also how to connect and get it back using a Web Bluetooth webpage.

But basically you can store to RAM which is easy and will likely work well enough for you, or you can write to Flash memory so the data persists even after power off.

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:

```

Just like Github, a blank line must precede a code block.
