Industrial IoT

In the Internet of Things devices become connected to the Internet. However, in complex industrial environments devices also need to communicate with each other directly.

This means enabling Microcontrollers to send and receive messages as well as triggering tasks.

Direct Communication

Concept Reply was challenged with developing a solution for communication between two microcontrollers:
an existing application controller and an external Network Access Device powered by another microcontroller.

During this process the team learned five lessons for the design, which they share in the whitepaper:
  • Lesson #1: How to avoid invalid message payload
  • Lesson #2: How to fix uncoordinated responses
  • Lesson #3: How to make sure, messages are delivered
  • Lesson #4: How to avoid messages to be sent too often
  • Lesson #5: How to handle limited memory sizes
