Hi Jarkko,

Most of your settings are familiar to us but one is not, could you tell us what "SEMEL_SETTINGS" is doing? That is not a define we provide and we would need to know what else it might be enabling/disabling.

Could you also provide us with some more details on your project given the commercial nature of the evaluation we will want to have a better understanding of your end goals and design to better support your efforts.

If you send an email to "support@wolfssl.com" we can better service you from a commercial standpoint as well. This will allow you to communicate to us details you may wish to remain out of scope of the public forums.

Prior to attempting a client/server handshake we always encourage users to verify the underlying crypto is working properly. There is a test application located here: <wolfssl-root>/wolfcrypt/test/test.c. Could you try building and running that application  to make sure all tests pass? Our suspicion is that there may be an issue with the crypto libraries in your environment that will need to be addressed prior to performing a successful SSL/TLS connection.

Best Regards,

Kaleb
