https://devzone.nordicsemi.com/f/nordic-q-a/62086/nrf52832-uicr-write-through-dfuHi, Greetings! We have successfully checked DFU application from SDK16.0.0 and it works nicely. We have used android nRF connect app for firmware updating. Here we have came across a issue and we wish to resolve it. Details are as below 1.

DFU doesn&#39;t touch the UICR. But for storing Firmware Version I don&#39;t recommend using UICR. Store it in the appliation itself, or in an FDS record.</p> <p></p> <p>BR,<br />Edvin</p><div style="clear:both;"></div>
