IoT Device Engineering

IoT – Networking – Control

Leveraging extensive experience with internet of things engineering and IoT app development, Cardinal Peak empowers clients with the ability to quickly design products that seamlessly integrate with mobile applications and cloud systems. By their nature, IoT systems are complex and require detailed knowledge of communications protocols, security standards, data collection, AI/ML and analytics. As many IoT applications are high volume, designing to minimize both the device BOM and the long-term cloud costs is crucial. Our team understands those requirements and possesses the skills and experience necessary to develop connected devices that can thrive in today’s networked ecosystems.

Our deep IoT expertise ensures your connected product will be intuitive to set up and use while maintaining security. We work with many of the major IoT platforms and component suppliers. Use our experience to help you reduce both cost and time to market by appropriately leveraging existing technologies.

FAQs About IoT Engineering Design Services

What is internet of things engineering?

At their most basic, IoT products consist of the following:

  • “Things,” which are small electronic devices with embedded communications, such as Wi-Fi, Zigbee, LoRa, etc. Common examples are connected thermostats, locks and lights.
  • A cloud application that manages the devices and user accounts. The cloud application communicates with the things, generally storing historical data and managing over-the-air (OTA) software updates. The cloud also authenticates devices and users to manage security.
  • An end-user app that lets consumers control their devices and view any data produced.

IoT engineering encompasses all the tasks required to ensure the thing, cloud application and end-user app perform their functions and work seamlessly together.

What are the steps in creating an IoT product?

  1. The first step in all product design is envisioning the value proposition of the product (ideation) and documenting the features that need to be implemented (the requirements). For an IoT product, the first engineering step is to describe the data that needs to be collected, processed and displayed so the device-to-cloud and the cloud-to-app interfaces can be defined.
  2. Given a good interface description, the development of the device, cloud application and end-user app can proceed in parallel as engineers work to the API (application programming interface), which has likely been mocked up with a test harness.
  3. As features are implemented from end to end, the system starts undergoing regular QA testing for each new feature and regression testing for previously developed features.
  4. When the system is complete, testing expands to alpha testing (“friends and family”) then beta testing (a small set of customers). During this period, any manufacturing test and configuration tools are prepared.
  5. Finally, the product is released. As widespread user data comes back and the marketing team sees what resonates with customers, features are added or tweaked and pushed out through OTA updates.

How is IoT app development different?

Developing IoT apps for smartphones differs from other app development in one important way — IoT apps interact directly with physical devices for command and control, onboarding (registration and Wi-Fi connection), and OTA embedded software updates. While this may seem like a subtle point, app developers that are not used to interfacing with hardware devices often do not understand the complexities involved.

First, hardware devices generally make use of a state machine so they might behave differently when in different states. The IoT app needs to be able to navigate these states. Second, hardware devices generally require time to perform their actions. For example, telling a space heater to start heating can take many seconds and while heating up, it will not respond to commands. App developers that are used to working with API calls to the cloud are used to instant answers and behaviors. Finally, OTA updates often require special attention. While silicon vendors provide reference code for both the app and the device, this code generally does not solve all the problems, so it is necessary to tweak it to accommodate differences.
