Have a look at the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/aws_fota/README.html">AWS FOTA Sample</a> and the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/http_application_update/README.html">HTTP application update</a>.<br /><br />Kind regards,<br />Øyvind</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/211325?ContentTypeID=1Mon, 23 Sep 2019 14:16:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0042350a-4493-4a27-9711-24a92ce20c07titof49<p>Ok, if i can flash the nrf91 app by ota, its sufficient.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/211113?ContentTypeID=1Mon, 23 Sep 2019 07:33:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a25fe33b-7a50-4b5c-bf22-31082200df27&#216;yvind<p>Hello,&nbsp;<br /><br />Using the nRF52840 DK, you can program the board controller (nRF52840) on the Thingy:91. Make sure to set the SWD Select to nRF52. It is not possible to flash the nRF9160 using a nRF52840 DK, as the onboard debugger is not correct.<br /><br />Kind regards,<br />Øyvind</p><div style="clear:both;"></div>
