This application is a reimplementation of an example application that RedBearLab provides (iOS example app - Source code, Android example app - Source code). The example is a chat application that shows how to communicate between multiple mobile phones connected to the RedBearLab board by sending text messages in both directions.
You can browse the source code for this example at the Evothings GitHub repository.
This example runs in Evothings Viewer on Android or iOS.
An iOS device or an Android device with support for Bluetooth 4.0 (which includes BLE) is required. For Android version 4.3 or later is needed.
You need one of RedBearLab development boards that has an implementation of the Simple Control example available, for example Blend or Blend Micro. You can also use an Arduino with a BLE Shield. (No additional hardware components are needed for the chat example.)
