Hello everyone,
I am currently developing an IoT device using ESP32 and I am looking to implement an automatic firmware update feature through OTA (Over-The-Air) functionality. Specifically, I would like to integrate OTA capabilities into the device so that remote firmware updates can be conducted wirelessly after the device is deployed. However, I have some questions regarding how to set up automatic OTA firmware updates on the ESP32, and I am hoping to get some guidance here.
Choice of OTA Libraries: Before I begin, I would like to know about reliable OTA libraries suitable for the ESP32 platform. Are there any libraries that are particularly beginner-friendly?
Firmware Version Management: When conducting OTA updates, how is firmware version management handled on both the device and server sides? How does the device detect and trigger an update if its firmware version is outdated?
Security During Update: I am highly concerned about the security of the firmware update process. How can the update process be secured to prevent man-in-the-middle attacks or data tampering?
Update Interruption Due to Power Loss: What happens if the device loses power during the update process? Could a power loss during update potentially brick the device?
Handling Downgrades: If issues are discovered with the new firmware after an update, do I need to provide a rollback mechanism so that the device can revert to its previous working state?
Update Progress and Feedback: During the OTA update process, can I obtain information about the update progress and status feedback? This is crucial for monitoring the smooth progress of updates remotely.
I am not very familiar with the OTA update feature of ESP32 and I am hoping to receive detailed guidance and suggestions so that I can successfully implement this feature. If you have any relevant experience or knowledge, I would greatly appreciate your insights. Thank you very much!
