https://devzone.nordicsemi.com/f/nordic-q-a/114473/nrf9160-persist-ramHi When doing a Software reset the RAM contents are persisted, however when doing a Hardware reset via nREST pin on the module then the non-initialized RAM section is lost, is there a way to keep the RAM contents thru a hardware reset ?

On the nRF91 series RAM content will in practice often be lost as regulators etc are reset powering down the RAM for a long enough time to loose the content.</p> <p>Br,</p> <p>Einar</p><div style="clear:both;"></div>
