https://devzone.nordicsemi.com/f/nordic-q-a/56312/ble-proximity-dfu-code-not-advertisingHi, I merged DFU code with Nordic Proximity BLE code. As i did it using this link https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.3.0%2Fservice_dfu.html after doing that my code is being compiled with no errorsen-USTelligent Community 13Wed, 08 Jan 2020 13:18:31 GMThttps://devzone.nordicsemi.com/thread/228143?ContentTypeID=1Wed, 08 Jan 2020 13:18:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:896ad56f-f89c-4eb3-9920-25dcdcd53b3bHung Bui<p>Hi Usman,&nbsp;</p> <p>Please try to debug and find what cause the assert. The debug guide can be found <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/#60126">here</a>.<br />Could be that you would need to increase the number of Vendor UUID&nbsp;NRF_SDH_BLE_VS_UUID_COUNT since the DFU buttonless service is Vendor specific.&nbsp;</p> <p>You also need to modify the RAM configuration if the softdevice complains that it&#39;s not enough ram for the softdevice.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/228106?ContentTypeID=1Wed, 08 Jan 2020 11:11:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b637a0bc-3ccf-4974-9ce9-e3d9a3ee23f5Usman Rahim<p>The code started working when i commented&nbsp;peer_manager_init(); in main</p><div style="clear:both;"></div>
