I need configure a service to receive normal tcp connections and tls connections in a same port. Is it possible using wolfssl and wolfSSL_read funcion? If yes, I also need to identify if a connectio arrive using SSL or no, how I do it?

I did a test and I can receive TLS connections but when a try receive a TCP packet, wolfssl return this error log. (err = -311, unknown type in record hdr).

below a resume of my configuration

    wolfSSL_Init();

    xWolfSSL_ServerContext = NULL;
    /* Attempt to create a context that uses the TLS 1.2 server protocol. */
    xWolfSSL_ServerContext = wolfSSL_CTX_new(wolfTLSv1_2_server_method());

    if (xWolfSSL_ServerContext != NULL) {
        int result = NULL;
        // Load the Root CA certificate.
        result = wolfSSL_CTX_load_verify_buffer_ex(xWolfSSL_ServerContext,
        &ca_cert_pem, (long) sizeof(ca_cert_pem),
        // Load the Intermediate CA certificate.
        (int) SSL_FILETYPE_PEM, 0, WOLFSSL_LOAD_FLAG_DATE_ERR_OKAY);
        result = wolfSSL_CTX_load_verify_buffer_ex(xWolfSSL_ServerContext,
        &int_cert_pem, (long) sizeof(int_cert_pem),
        (int) SSL_FILETYPE_PEM, 0, WOLFSSL_LOAD_FLAG_DATE_ERR_OKAY);
        result = wolfSSL_CTX_use_certificate_buffer(xWolfSSL_ServerContext,
        &server_cert_pem, (long) sizeof(server_cert_pem),
        (int) SSL_FILETYPE_PEM);
        result = wolfSSL_CTX_use_PrivateKey_buffer(xWolfSSL_ServerContext,
        &server_key_pem, (long) sizeof(server_key_pem),
        (int) SSL_FILETYPE_PEM);

WOLFSSL* xWolfSSL_Object;
    int err = 0;
    char errBuffer[80];

    /* A connection has been accepted by the server.  Create a
     wolfSSL object for use with the newly connected socket. */
    xWolfSSL_Object = NULL;
    xWolfSSL_Object = wolfSSL_new(xWolfSSL_ServerContext);

    if (xWolfSSL_Object != NULL) {
        /* Associate the created wolfSSL object with the connected socket. */
        xReturned = wolfSSL_set_fd(xWolfSSL_Object, conn->socketHandler);
        while (1) {
              count = wolfSSL_read(xWolfSSL_Object, (char *)buffer_req, BUFSIZE);
              }
        }
