The first uRADMonitor devices used the mega168, but the project grew in complexity so the upgrade was natural.

I was wondering if it would be possible to integrate OTA, using an exotic technique: having the code run in the first 16KB section of flash (offset 0), download the new firmware in the second section (offset 16K), than move new firmware block to offset 0 when download is ready. This might require a bootloader. I wonder if its possible to do it without one?

Anyone has any experience with this?
