Fota Update in IoT

FOTA update in IoT , which stands for Firmware Over-The-Air, is a technology that allows IoT devices to be updated remotely without the need for physical intervention. This is a crucial capability for IoT devices, as it enables manufacturers to fix bugs, improve performance, and add new features without having to recall or replace devices.

The FOTA process typically involves the following steps:

  1. The manufacturer develops and releases a new firmware update. The update is typically stored on a secure cloud server.

  2. The IoT devices periodically check for updates. If an update is available, the device will download it to its internal storage.

  3. Once the update is downloaded, the device will install it. This may involve restarting the device or taking it offline for a few minutes.

  4. After the update is installed, the device will be running the latest firmware.
