Real Time Logic LLC / Mbed 2 deprecated SharkMQ-LED-Demo

Example program that shows how to use the Secure (TLS) SharkMQ library included in SharkSSL-Lite

Dependencies:   EthernetInterface SharkSSL-Lite mbed-rtos mbed

Introduction

The SMQ Architecture is an Internet of Things (IoT) publish subscribe end-to-end solution that is optimized for embedded systems to provide instantaneous Device Edge Node connectivity, 1 to 1 Communications, and Ease of Transcending Firewalls. The solution is ideal for resource constrained devices that require real-time dynamic control, analytic information, and firmware updates in both LAN and WAN environments.

Architecture Component List

  • SMQ C Client (Non-secure)
  • SharkMQ Secure C Client (this mbed example)
  • SMQjs (Javascript)
  • SMQ JAVA
  • SMQ Broker

How to setup your own secure SMQ IoT cloud server

Most IoT cloud server solutions, whether they provide ready-to-use hosted services or not, are based on a standard Virtual Private Server (VPS). Most developers probably think of Amazon or Microsoft Azure's services when considering the server side of their IoT solution. These high-end services are great if you need to scale up to millions of connected devices. However, for most small-scale operations and DIY projects, a low-cost VPS is more than adequate.
