Hi.
I'm using ATSAMD21G18A CPU with the arduino bootloader on, in several IoT projects.
I would like to get into OTA functionality.
I have looked at the ArduinoOTA library, and it looks interresting.
However as far as i can see there is no fall back functionallity if the OTA procedure fails.
What I would like is something than runsalong side the bootloader. So even if the OTA fails, the
bootloader remains intact.
I'm somewhat of a novice in Embedded Programming, so I'm not sure where to start.
Is there a way to only flash part of the MCU, and leave some of the code intact.
I would appreciate any help pointing me in the right direction, as I'm pretty lost
to what is the best and easiest way to handle this
Many Thanks in advance
