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

Actually i am having problems with DTLS connection

The device initiates the DTLS handshake with a "Client Hello", which is correct.

The problem appears to be the destination, which is 0.0.0.0. Which server/IP address are you trying to connect to? What is CONFIG_SERVER_ADRESS defined as?

static int server_initialisieren(void)
{

	struct sockaddr_in *server4 = ((struct sockaddr_in *)&server); // Socket-Adressstruktur für IPv4

	server4->sin_family = AF_INET; // AF_INET  = IP Protokoll Version 4 (IPv4)
	server4->sin_port = htons(CONFIG_SERVER_PORT); //Schreibe Port in Network-Byte-Order in das Feld sin_port

	inet_pton(AF_INET, CONFIG_SERVER_ADDRESS,
		  &server4->sin_addr); // Schreibe IP-Adresse des Servers in die sockaddr_in-Struktur
  

	return 0;
}

Regards,

Markus

CONFIG_SERVER_ADRESS is "californium.eclipseprojects.io" and the IP address is 35.185.40.182
