  • Thread-topic: Issues in Leshan Server and Client version 1.0.0-M13 with pre-shared key using DTLS1.2

Hello,
I am working with leshan 1.0.0-M13, I am trying to establish communication between LeshanServerDemo and LeshanClientDemo with pre-shared key using DTLS1.2. On both the sides, I have seen configurations for UDP only. The following are the changes that I made on the code:

  1. I have added the client security configurations on server.
  2. I have passed thes options -i leshan -p 1234 -n client1234

 

I am able to see the client using coaps URI to connect with server.But, in the wireshark captures I am getting TCP packets and TLSv1.3. I have these following queries:

  1. Which transport does it support TCP or UDP?
  2. If it is UDP, does it support DTLS?
  3. If it supports DTLS, which version of DTLS is supported? Is it 1.0 or 1.2?

 

Please resolve these queries asap.

BR,
Sarthak.
