ESP32 MQTT over TLS 1.3 有人试过了吗？TLS 1.3 handshake over之后出错

[Chozmao]

有人在esp32上成功跑过 TLS 1.3吗？
用的master esp-idf 5.0, 然后 mbedtls用的是branch mbedtls git:(mbedtls-3.1.0-idf)
我想测下MQTT over TLS 1.3
在menuconfig里面enable了tls 1.3
第一次 tls 1.3 的handshake没问题，ssl状态在WRAPUP后设置为 MBEDTLS_SSL_HANDSHAKE_OVER
然后在 ssl_handle_hs_message_post_handshake（）函数里面报错，
我看了下是收到了NEW_SESSION_TICKET 包裹。
原代码在这边就直接 return UNEXPECTED_MESSAGE了。

Code: Select all

        MBEDTLS_SSL_DEBUG_MSG( 1, ("hangmao debug: post ssl handshake '%d'", ssl->in_msg[0]));
        //if (ssl->in_msg[0] != MBEDTLS_SSL_HS_NEW_SESSION_TICKET)
            return( MBEDTLS_ERR_SSL_UNEXPECTED_MESSAGE );

known bug. mbedtls 库对TLS 1.3 的支持还不完善
