I just wanted to fill in one thing that is good to know here. The nRF9160 has one application core (an ARM Cortex M33), as well as a complete LTE modem. More specific information can be found in the nRF9160 PS. So as awneil says, it would likely make more sense to have your application on the nRF9160 M33 core, than on a separate nRF52840.

Best regards,

Simon

Here is the link for the Thingy 91 Q&A: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/q-a-for-introduction-to-nordic-thingy-91-webinar

I apologize, I was directed to the Q&A page from the link I posted so I incorrectly assumed it was a Thingy 91 specific Q&A forum.

I understand now, so it's likely recommended to primarily use the 9160 because it's the more powerful processor?

please give a link so that we can see it in context.

[quote userid="93959" url="~/f/nordic-q-a/66849/main-program-on-9160-vs-52840"]why should one put the application on the M33 vs the M4 (9160 vs 52840)? [/quote]

Not sure what you mean by that?

The nRF9160 doesn't have an M4 core; the nRF52840 is a single-core chip.

If you're having the nRF9160 and nRF52840 together in your design, it would probably make most sense in general to have your application in the M33 core - as that's the more powerful, and isn't also having to run any radio stack.

But your application may have specific reasons to do otherwise - only you know the details.
