How to add DTLS to nRF coap client

[ced27]

Hello,

i ran  nRF Coap Client and it worked pretty well.

I am working with nRF9160 DK.

Now, I want to add DTLS to this example to secure the data.

Can someone please help me or is there any tutorials on how to do that?

Best regards,

Cedric

Hello Cedric,

please be aware that DTLS only is experimental and not officially supported in NCS. Except from enabling the mentioned configuration parameter, you have to reconfigure the socket using a DTLS protocol type.

I recommend you to have a look at the Echo Client sample, which demonstrates the usage of the corresponding API.

Regards,

Markus

Hi Markus,

thanks very much for your reply.

I used nRF Connect Trace Collector to capture the trace files of the modem, so i could see if the encrytion has done, but i had some issues with it.

Here is the trace as attachment, you can open it with wireshark and have a look at it and please help me find a solution for the issue.
