Nordic Pucks / Mbed 2 deprecated location-puck Featured

The Location Puck gives your smartphone context about its location. Built on the Puck IOT platform.

Dependencies:   Puck mbed

The location puck will give your smartphone context about the phone’s location. You can later set up rules for what should happen at different locations in the smartphone companion application (Puck Central).

A tutorial for the Location Puck is available on GitHub.

Tutorials and in-depth documentation for the Puck platform is available at the project's GitHub page
