I am trying to connect a wp77 to AWS IoT and I was wondering if there is any available app which support TLS authentication for mqtt protocol. Cheers

Which legato application are you using for compilation?

mmmhhh, good question… I believe I am using the latest legato application 20.04 but how do I check it? I can see the leaf version is 2.3.1

as you say “it works”, I thought you already compiled something…
