Software Install instructions for the PhoneGap Day NY 2017 - Hands on Bluetooth LE Workshop

Hands-on Bluetooth Low Energy

PhoneGap Day NY - October 12th, 2017

Software Installation

In order to get the most of the class, we're asking everyone to install the software before the workshop.

It's important that you follow this guide and have you computer setup before you arrive. We want to spend time learning about Bluetooth not installing software.
