Hello there,

I am working on a project that involves deploying firmware over the air updates for a fleet of IoT devices. While I have some experience with embedded systems; this is my first time implementing FOTA; and I want to ensure that I follow best practices to make the process as smooth and reliable as possible.

What are the recommended strategies for securing the update process? 🤔 I have read about signing firmware images; but I am curious if there are additional measures to prevent unauthorized access or tampering.

How do you handle scenarios where a firmware update fails or is interrupted? Are there specific techniques for ensuring that devices can recover gracefully without becoming bricked? 🤔

Since some of our devices operate in areas with limited connectivity; I am concerned about optimizing data usage. Are there any methods or protocols you recommend for minimizing the size of firmware updates; perhaps through differential updates or other techniques? 🤔

For end users; especially those not tech-savvy, what are some ways to make the update process more user friendly? Should we aim for silent updates; or is it better to provide notifications and options for manual updates? 🤔

Also; I have gone through this post; [https://memfault.com/webinars/device-firmware-update-best-practices-](https://memfault.com/webinars/device-firmware-update-best-practices/)[blue-prism/](https://www.igmguru.com/machine-learning-ai/blue-prism-training/) which definitely helped me out a lot.

Are there any tools; libraries; or frameworks that you have found particularly helpful for managing and deploying FOTA updates? 🤔 We are currently exploring various options; and it would be great to get recommendations based on practical experience.

Thank you in advance for your help and assistance. 😇
