Filtering out Espruino Devices

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!
