Filtering out Espruino Devices

I'd like to be able to do a BLE scan and separate Espruino from non-Espruino devices. Is there information in the BLE advertisement packet, or any other way, to do this?

You can do it a few ways:
- Separate by the name - whether it starts with Puck.js
- Separate by the UART UUID so only serial devices like Espruinos show up - although this can fail in high-traffic areas as the UUID is stored in a scan response packet
- Add your own UUID (or the manufacturer code 0x590 that's registered for Espruino) to each Espruino you care about, and filter off of that.
The Web IDE uses a combination of the first two (because the second isn't reliable enough).

Hope that helps!

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.
