There is <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.5.2/nrf/device_guides/working_with_nrf/nrf52/developing.html#fota-over-thread">no support for FOTA over OpenThread</a> in nRF Connect SDK.</p> <p>You can add MCUboot as a second stage bootloader to perform firmware updates.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
