Trouble After Closing A Socket

[kackle123]

Hello,

I took the HTTP/web server example of MQX 4.2.2 and added wolfSSL-based, encrypted email to it (multitasking).  However, when the code closes the email socket after sending the SMTP QUIT command, the web server stops functioning, even though the TAD shows no obvious problems.  The bottom of the code looks like this:

ret1 = wolfSSL_shutdown(ssl);

wolfSSL_free(ssl);

wolfSSL_CTX_free(ctx);

ret2 = wolfSSL_Cleanup();

ret3 = shutdown(socketNumber, FLAG_CLOSE_TX); 

I think it all returns okay:

ret1 = 2, acceptable according to wolfSSL code comment.

ret2 = 1

ret3 = 0

Thank you for your suggestions.

Thank you for your response.  I can try asking the WolfSSL company, but I hope I don't get caught between their blaming MQX, and NXP/MQX blaming WolfSSL!

Hi

SSL is supported by MQX but provided by our third party partner wolfSSL. You may look at third party options WolfSSL.
