https://devzone.nordicsemi.com/f/nordic-q-a/115713/ota-hardware-requirementsHello, I&#39;m curious if there is a dependency to use the same Bluetooth module to perform OTA. If I created my own custom board, would I need to use an identical Bluetooth module? Can I use a different module and still perform OTA? If so how?

However, depending on your board design, there may be differences in pinout, clock sources, DCDC regulator support, etc., which are relevant not only for OTA but also for the application to work properly. Do you plan to use different modules on your custom board?</p> <p>How to enable FOTA in an application is covered by this devacademy course at:&nbsp;<a href="https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/">https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/</a>&nbsp;</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
