https://devzone.nordicsemi.com/f/nordic-q-a/55554/s113-buttonless-dfuHi, The buttonless DFU example mentions support for S112, S132 and S140: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fble_sdk_app_buttonless_dfu.html&amp;cp=4_0_0_4_1_2_6 Does it work on S113? If not, whaten-USTelligent Community 13Thu, 12 Dec 2019 12:13:05 GMThttps://devzone.nordicsemi.com/thread/225145?ContentTypeID=1Thu, 12 Dec 2019 12:13:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:473db5c5-ec79-416d-b310-3c52fe33f934bjorn-spockeli<p>Hi Chethans,&nbsp;</p> <p>Yes, it should be possible to take the S112 example for Buttonless DFU and the Secure bootloader example for S112 and port it to the S113. It should just be a matter of replacing the SoftDevice header files and setting the correct Softdevice definition in the Preprocessor definitions, i.e. replace S112 with S113.&nbsp;</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
