“With the IoT booming nowadays, the number of connected devices grows exponentially and so does the related software that drives them. There is no doubt that Firmware Over The Air (FOTA) is a highly desirable if not required feature for any embedded project/product both DIY or commercial. Being able to provide a remote firmware update is obviously very beneficial. The opportunity here is to enhance product functionality, operational features and provide fixes for particular issues. Updating the firmware OTA may eliminate the need to bring a product into a service center for a repair. Although not every issue can be resolved with a firmware update, if one is available for a particular issue, it can save a lot of time and money.”
