[gnutls-help] PSK DTLS

[mk]

Does anyone know of any (gnuTLS) examples of DTLS using PSK?

I am working on a C++ network socket library which wraps gnuTLS (the C 
API); TLS and DTLS are working client and server side using X.509, and 
TLS using PSK.  However, DTLS using PSK fails client side during the 
handshake, after the DTLS cookie is sent, with "A packet with illegal or 
unsupported version was received".

Existing examples in the manual and online have been invaluable to me 
with the work up to now, but I have been unable to find any for this.
