I would like to perform Firmware update Over the Air. I guess it is what is call DFU.
Where can I found example and documentation to use it ? I tried but fail ! the DFU service is not recognized by the Nordic dedicated Android application.
Second question: is the DFU using the QSPI Mem (which is on the xiao board) ? and if yes, what remains left for my application, if any ? I want to keep part of the memory even when I perform FW update.
Finally: my application is very low power app (if must stand for weeks on a 150mAh). Is the DFU compatible ?
