[tinydtls-dev] DTLS Role Exchange

[Simon Bernard <contact@xxxxxxxxxxxxxxx>]

Hi Olaf,

  I'm currently investigate if role exchange could make sense in DTLS.

  Here is a page[1] where I described a bit the idea.

  It seems that the way tinyDTLS is implemented is compatible with this idea. The documentation[2] is saying : "A DTLS client is constructed like a server but needs to actively setup a new session by calling dtls_connect() at some point. "

  I tested the current dtls-client from tinydtls with my dtls-server tool[3], and it does not works. The issue is just detail, I fix it in this branch[4]. (sorry not enough courage to use gerrit :-p)

  Anyway, I would be interested by your opinion about this.

Simon
