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!
