Re: [leshan-dev] Issues in Leshan Server and Client version 1.0.0-M13 with pre-shared key using DTLS1.2
|
Hi,
It is strongly recommended to use stable version of Leshan and
not milestones one (like M13...)
Leshan 1.x (which is the current stable version) only support
CoAP over UDP and CoAPs over DTLS 1.2.
Maybe one day Leshan 2.x (which is in development, meaning no
stable version released) could support CoAP over TCP and CoAPs
over TLS 1.2 but not at short term.

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:
- I
have added the client security configurations on server.
- 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:
- Which
transport does it support TCP or UDP?
- If
it is UDP, does it support DTLS?
- If
it supports DTLS, which version of DTLS is supported? Is
it 1.0 or 1.2?
Please
resolve these queries asap.
BR,
Sarthak.
