Hello all,
I'll take a moment to explain the context of use:
- I'm using the wolfSSL library C# wrapper to develop a TLS1.3 client.
- The client communicates with the server (a ST NUCLEOH743ZI2 board) throught UART serial port.
- I've just created two working clients running on linux distribution and cygwin.
Using the C# wrapper on VisualStudio I've encuntered the following problem:
When starting handshake procedure with the server the client sends the following client_hello packet:

The server answers with:
15 03 03 00 02 02 32
And error -328 BUFFER_ERROR is raised, the client reports -313 FATAL_ERROR.
I've also double checked that data sent by client are received by the server.
Can you help me?
Thank you,
Mattia
