Retransmission doesn't work in dtls handshake

[ccli8]

Environment

Platform: Ubuntu 18.04 aliyun/iotkit: RELEASED_V2_1_20180320 Test code: sample/coap/coap-example.c

Description

Hi,

I am testing coap example but fail in dtls handshake. To help debug, I set mbedtls debug level to 2. src/platform/ssl/mbedtls/HAL_DTLS_mbedtls.c:

dtls_session_t *_DTLSSession_init()
{
    dtls_session_t *p_dtls_session = NULL;
    p_dtls_session = coap_malloc(sizeof(dtls_session_t));

    
    mbedtls_debug_set_threshold(2);
    

And I get log below. I've run several times and find that when -0x6800 error is met, mbedtls tries to re-transmit but the mechanism doesn't work.
