Tls error SSL_FEATURE_UNAVAILABLE

[yuan_zhang]

Dear all,
I Used the TLS client of mbedtls-2.26.0 to connect to a TLS server,

1. Client settings: if ((RET = mbedtls_ssl_conf_max_frag_len (& Conf, mbedtls_ssl_max_frag_len_1024))! = 0)

2. Tls1.0 protocol is adopted for client and server.

3. The server transmits three certificates with a certificate size of 3420 bytes.

Then i got a problem:
During Handshake:
mbedtls_ssl_handshake_client_step
case MBEDTLS_SSL_SERVER_CERTIFICATE:
ret = mbedtls_ssl_parse_certificate( ssl );
Error：
/* With TLS we don’t handle fragmentation (for now) */
if( ssl->in_msglen < ssl->in_hslen )
{
MBEDTLS_SSL_DEBUG_MSG( 1, ( “TLS handshake fragmentation not supported” ) );
return( MBEDTLS_ERR_SSL_FEATURE_UNAVAILABLE );
}
So,why? And how to issue this problem?

Thanks a lot!!!

Hello,

Try to look at this

mbedTLS + NUCLEO-F401RE + SIM800

Hi Dimitris, As you can see, error -0x7080 is MBEDTLS_ERR_SSL_FEATURE_UNAVAILABLE which is returned by several locations, when a requested feature is not supported. Usually it is a configuration issue. This is not related to the platform, or the entropy source (though you do need an entropy source to the functionality). I would suggest you look at the debug logs for you to understand where this error is returned, and then you could configure the relevant feature if possible. Regards, Mbed TL…

BR, Jan
