mbedTls NONOS SDK 2.1 HTTP Server fatal exception

Postby chinnaobi » Tue Aug 22, 2017 6:52 pm

Hi All,

I have been playing around with new libmbedtls.a library downloaded from espressif SDK (precompiled from herehttp://espressif.com/sites/default/ ... 160718.zip ) .

It seems there is an issue running IOT Demo HTTP server SSL enabled using mbedTls library. Once I start a client connection this is what happens
=== System init ====
mode : softAP(62:01:94:84:0d:2e)
add if1
dhcp server start:(ip:192.168.4.1,mask:255.255.255.0,gw:192.168.4.1)
bcn 100
add 1
aid 1
station: 90:61:0c:32:59:29 join, AID = 1
server handshake start.
server handshake ok!
server's data invalid protocol

I have set the SSL settings as follows on the HTTP server

Code: Select all

espconn_secure_set_size(ESPCONN_SERVER, 4096);
         espconn_secure_set_default_certificate(default_certificate, default_certificate_len);
        espconn_secure_set_default_private_key(default_private_key, default_private_key_len);
        espconn_secure_accept(&esp_conn);


I have tested by increasing the size of espconn (6*1024), same happens.

Any idea, why it's happening? What am I missing?
