Over-the-air (OTA) software updates in embedded MCU based applications
Many MCU based embedded systems are used in a variety of IoT applications which are typically deployed in the field on a large scale. These devices coupled with the rapid software development cycle, cause many systems to require support for over-the-air (OTA) updates. In this process, an OTA update replaces the software and firmware on the microcontroller (MCU) of the embedded system with a new so...Read the article
The intersection of modern OTA updates and configuration management
The term over-the-air (OTA) updates is today often used interchangeably with “software updates” in the context of connected devices and IoT.
However, the term originates from the telecom industry, where it has been used for a much wider scope than just software. For example, a special type of SMS message from the cellular provider to all phone subscribers can change the way phones are configure...Read the article
Choosing Yocto as your build system for your IoT project
Going from prototyping to production, one has many options to choose from to develop their IoT project. Yocto and other open source build systems such as Buildroot provide an automated, reliable and reproducible way to generate custom distribution images. Additionally, choosing a build system gives you complete control of the software and you can configure it to do anything you wish. It enab...Read the article
How to do delta (differential) updates with Mender
Using binary deltas for applying updates is a more efficient mechanism for updating software over-the-air (OTA) which enables faster downloads and bandwidth cost saving for metered networks. When using cellular (e.g. 4G/LTE) or other bandwidth constrained networks, the impact is even greater. With the recently announced commercial editions, Mender offers the ability to generate and only deploy t...Read the article
Introducing the tutorial category on Mender Hub
Mender Hub is our community platform and so far we had two primary categories:
- General discussions
- This is for feature requests, feedback about the Mender project, help requests and more.
- Board integrations
- This is the place to find resources for integrating...
