System Design for IoT: (FOTA/OTA)Firmware Updates for IoT devices|Embedded systems

System Design: A very basic Fota architecture for IoT devices, the same design can be extended to any microcontroller.
we discussed in brief on What Fota is? and how is it different in general computing devices and embedded IoT devices.

How do we take care of the re-request of files incase of roll back??

[@samineni100]

With this particular setup, I would prefer to always have a copy of the bin file for the previous version In the ESP32,So that In case of any failure we can rollback easily.

Could you brief about how FOTA is done over LTE network??

[@samineni100]

Hello
Inside the flash of a microcontroller, we write a very small piece of code (bootloader) that will download the file to another sector of flash memory, from LTE using the chosen protocol (HTTP,FTP,e.t.c). Once it is verified that it is a successful download then the bootloader handles control to the newly downloaded firmware.
you can watch my dual-booting a microcontroller video to understand more.
Meanwhile, since it is an interesting topic I will try to a make a video on this.
Thank you.
