Blynk Board Bridge Widget Demo

Contributors: .Brent.

Introduction

The Bridge Widget available in the Blynk app allows for Device-to-Device communication. No app is required to be running. This demo shows a few ways the Bridge widget can be used for app to app communications, app to board communications, and board to board communications.

For full functionality, two mobile devices and two SparkFun Blynk Boards are required. If you aren't interested in app to app communications, only one mobile device will be required. Mobile devices can be running Android or iOS.
