Over-the-Air Updates to IoT Devices with NGINX
Over-the-Air Updates to IoT Devices with NGINX .indented { padding-left: 50pt; } The Internet of Things (IoT) is already all around us – from voice‑activated devices to lights, coffee machines, and fridges – and we interact with it everyday in ways we don’t always realize. One of the biggest challenges in scaling IoT devices is device management, particularly over-the-air updates, commonly called OTA. OTA is critical to deploying new firmware to IoT devices; without it user intervention is required, either by the consumer or by a technician visiting (possibly literally) the device in the field. This post demonstrates how to use NGINX Open Source or NGINX Plus as an API gateway to deploy OTA updates to devices automatically. (For ease of reading, I’ll refer to NGINX throughout.) I’m using a simple API to handle the firmware versioning (so the devices know which version [ more… ]
