All Kestrel Meters in the 5000+ series with LiNK can be connected to a Smartphone App (Android & iPhone).  Download from Google Play or iTunes.  Look for: Kestrel LiNK or Kestrel LiNK Ballistics.  

You can export date from your app to your computer very easily.

If you still need to connect to the computer via LiNK, you can get the Dongle, as BTLE will not directly connect to computers.

If you don't have LiNK, you need a cable to connect to your computer.
