https://devzone.nordicsemi.com/f/nordic-q-a/94315/fota-over-bluetooth-leHi all, I am trying to perform a FOTA upgrade over BLE with an nRF52832. I started with the zephyr sample &quot;peripheral_dis&quot; at zephyr/samples/bluetooth, and then followed all the steps here: https://developer.nordicsemi.com/nRF_Connect_SDK/docen-USTelligent Community 13Wed, 07 Dec 2022 19:33:45 GMThttps://devzone.nordicsemi.com/thread/399534?ContentTypeID=1Wed, 07 Dec 2022 19:33:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b522143b-b5af-49d3-ac7b-5c59e188e3c8Raoul<p>Hi Pablo, sorry for my late reply.</p> <p>Have you looked at the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.2/nrf/ug_nrf52.html#fota-upgrade-sample">FOTA upgrade sample</a>, from the page you linked to?</p> <p>One of my colleagues has also created a guide to adding FOTA / DFU (Device Firmware Update) support to your application:</p> <p>&nbsp;<a href="https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu">Add DFU support to your application</a>&nbsp;</p> <p>Following this guide, and comparing your implementation to the above examples is probably a good start.</p> <p>If the process gets stuck somewhere, try to enable logging (and <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/services/logging/index.html#logging">increase the log level</a>) and see what the issue is.</p> <p>If you have further questions, I&#39;ll be glad to help.</p> <p>Best regards,</p> <p>Raoul</p><div style="clear:both;"></div>
