I'm testing https for my application and I found http works but https fails.

The error is:

wiced_tcp_connect returns 1.

which is because wiced_tcp_start_tls returns 1.

which is because

    wiced_tcp_start_tls

    -> wiced_tcp_start_tls_with_ciphers

    -> ssl_handshake_client_async returns 1.

I remove some features in my application at compiler time and then https works.

It seems tls takes extra memory to work.

How much extra free memory is required to enable tls?

Is it possible to work at the MAC layer where I can see all packets regardless of addressing and build packets manually?  I would like to creat a test apparatus application that sniffs the network and can inject test packets.  I don't see any API support for this mode.  It is commonly supported in other chip sets such as the TI CC3200.

Hi abirjepatil​

I tried to run demo.aws_iot.pub_sub.publisher demo code on SDK-3.5.2.

But I got below error:

Joining : LAB

Successfully joined : LAB

Obtaining IP address via DHCP

Network ready IP: 192.168.1.103

Resolving IP address of MQTT broker...

Resolved Broker IP: 52.192.145.107

[MQTT] Opening connection...

[MQTT LIB] : error intializing the  mqtt connection setup

After adding debug code, it shows

wiced_tls_init_root_ca_certificates returns -96.

x509_convert_pem_to_der returns -64 because s2 is NULL.

Below print out the content of pointer p:

Obviously, it's incompleted so it returns TROPICSSL_ERR_X509_CERT_INVALID_PEM (-64).

Then I print out the content after resource_get_readonly_buffer() call

and got the same data as above.

Hello vik86​

As a follow on to this thread: Issue with MQTT reconnecting to broker if wifi connection goes down​

I'm also trying to make the same logic work. When disconnected, I deinit and free mqtt_object and do some other stuff. Then I recreate it and try to connect. However there seems to be a memory leak, I think it might be related with the linked list that the session creates. Is there a way to easily delete all the data related to mqtt connection? Here is the code I used for deinit :

  mqtt_connection_t *conn = (mqtt_connection_t*) mqtt_object;

  wiced_rtos_deregister_timed_event( &conn->heartbeat.timer );

  mqtt_connection_deinit(conn);

  wiced_mqtt_deinit(mqtt_object);

  free( mqtt_object );

Thanks
