Regarding the issue of space occupation on nrf52833 using the Secure Transport Layer (DTLS)

[Idle-xu]

I use the security mechanism dtls based on udp communication. Can I implement it on nrf52833? How much flash and ram should be occupied at least? Is there a suggested value?

Thank you very much to the nordic team

Hello,

Which SDK version are you using here? There is some dedicated reference for DTLS inside our old nRF5 SDK. For example, see this blog post, and also see the section on enabling secure communication with DTLS.

Kind regards,

Hello,

When it comes to the nRF Connect SDK, there is no out-of-the-box sample showcasing DTLS. However, I recommend referring to the cryptographic sample in this section. You can also generate a memory report from the Extension to get an idea of RAM and Flash usage after the build.

Kind Regards,

OK, I'll give it a try.
