OTA Firmware Updates: Crucial for IoT
In the early days of IoT, in order to make any firmware updates, you had to retrieve the device, take it apart, connect it to your computer, reprogram it, put it back together, and return the device to the field. As time progressed the industry has shifted to over-the-air (OTA) firmware updates, but the early days were rife with updates causing intermittent disruption and performance degradation.
Even today, stories will make the news about large companies “bricking” consumer products as they try to get this right. As IoT platforms matured, skilled developers in this industry have invested large efforts into mastering updating connected devices remotely and reliably with little to no disruption and great confidence.
OTA firmware updates are a critical factor for IoT success because they drive the reliability, extensibility, and security of connected devices. When a bug that affects business logic or security is discovered, it can be updated right away. If new features are developed, you can push them to your deployed Things, ultimately netting more value out of every device in your fleet.
Firmware is a large portion of all of the little cogs that make our world turn, and its presence will only continue to grow. Getting firmware right the first time is difficult. You have to manage everything from security to business logic to networking, all at some point on remote devices. Being able to leverage OTA firmware updates helps alleviate these problems, but it also introduces its own complexities.
