Introduction

When developing an application with a real-time operating system, developers have numerous design decisions to make when starting a project. These design decisions can greatly affect how a system performs, how easy it is to expand an application and even how well a system can tolerate failures.

The following blog series will take an in-depth look at designing a real-time operating system application in a dynamic multiprotocol system (Bluetooth + Proprietary Wireless). It will walk through configuring Micrium OS, discuss task architecture, look in-depth at the Bluetooth and Proprietary Wireless tasks, and look at some safety design patterns.

The goal of the application discussed throughout the blog series is to run the dynamic multiprotocol application on a Thunderboard Sense 2 board. There is a web application that will communicate over Bluetooth with the Thunderboard using the WebBluetooth API. The Thunderboard will also communicate to a Blue Gecko board via Proprietary Wireless. The image below shows the layout of communication.
