Firmware Over The Air (FOTA) refers to the process of delivering firmware updates to devices over a network, usually wireless, instead of requiring the user to physically connect the device to a computer or other external device. FOTA updates are commonly used in the context of Internet of Things (IoT) devices, smartphones, and other connected devices to fix bugs, improve performance, add new features, and enhance security. The update process is usually handled by an FOTA client that runs on the device and communicates with a server to download and install the update. This can be done in the background, with minimal user intervention, making it a convenient and effective way to manage firmware updates for large numbers of devices.
