https://devzone.nordicsemi.com/f/nordic-q-a/78623/recompile-samples-from-nrf9160dk-to-thingy-91Hello! There is a sample simple_mqtt which is written for nrf9160 DK. Is it possible to make app_signed.hex file to load in thingy 91. I tried to change prj.conf and have the fiile for thingy, but when I use nRF Connect v3.7.0 - Programmer v1.4.11en-USTelligent Community 13Mon, 16 Aug 2021 11:36:12 GMThttps://devzone.nordicsemi.com/thread/325088?ContentTypeID=1Mon, 16 Aug 2021 11:36:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0cf40d37-9c9c-4134-b4b2-1019bd0930af&#216;yvind<p>Glad to hear!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/325074?ContentTypeID=1Mon, 16 Aug 2021 10:58:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6b22b324-a5e2-41f4-b3a0-5f5387fa26afIIIapcep<p>Thank you for answer.&nbsp;I checked everything from the specified instruction <a href="https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/how-to-program-any-project-to-the-thingy-91-with-dfu">guide on how to add support for Thingy:91</a>.

The Thingy:91 needs bootloader support, which the simple_mqtt does not have out of the box. What version of the nRF Connect SDK&nbsp;are you working on? Have a look at this <a href="https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/how-to-program-any-project-to-the-thingy-91-with-dfu">guide on how to add support for Thingy:91</a>.<br /><br />Let me know how that works for you!<br /><br />Kind regards,<br />Øyvind</p><div style="clear:both;"></div>
