https://devzone.nordicsemi.com/f/nordic-q-a/122914/mcuboot-dfu-without-device-rebootHi, I am trying to perform a DFU using SMP over BLE.

Both images share the same secondary slot as a staging area, which means they must be updated one after the other.</span></p> <p><span>Thus, marking this ticket as&nbsp;resolved.
