Hi,
I am working on Murata1LD board
In my code, call to wiced_aws_disconnect causes program to hang. I suspect a memory leak. I followed the solution in below thread. But the issue is not yet solved.
Whenver , wifi connection is interrupted, the code hangs there. Apart from the solution mentioned in above thread, is there anything to be done.
Thanks,
Binsy M S

An issue was reported where there was a memory leak after multiple connections and disconnections to the AWS. Can you do the below changes and see if it fixes the issue?
Add the below lines in /43xxx_Wi-Fi/libraries/protocols/AWS/aws_mqtt.c in the function aws_internal_mqtt_disconnect() after the line ret = wiced_mqtt_disconnect( mqtt );
wiced_mqtt_deinit(mqtt); //Memory Leak fix
free(mqtt); //Memory Leak fix
mqtt = NULL;
Add the below line in /43xxx_Wi-Fi/libraries/protocols/AWS/wiced_aws.c in the function wiced_result_t wiced_aws_deinit( void ) after the tls_deinit
free(g_aws_thing.tls_identity);
Thanks

Hi,
I have already tried the below solution.
Add the below lines in /43xxx_Wi-Fi/libraries/protocols/AWS/aws_mqtt.c in the function aws_internal_mqtt_disconnect() after the line ret = wiced_mqtt_disconnect( mqtt );
wiced_mqtt_deinit(mqtt); //Memory Leak fix
free(mqtt); //Memory Leak fix
mqtt = NULL;
And the other one you mentioned is already present in the files of WICED-Studio-6.4
Add the below line in /43xxx_Wi-Fi/libraries/protocols/AWS/wiced_aws.c in the function wiced_result_t wiced_aws_deinit( void ) after the tls_deinit
free(g_aws_thing.tls_identity);
But the issue is not resolved with these solutions
Thanks,

Which is the application that you are using?
When does it hang?
Can you give me the steps to reproduce this?

I am trying to develop an application by modifying publisher project in wiced-studio. with qos =1, when it fails to get the publish acknowledgement , wiced_aws_disconnect is called to forcefully disconnect. After this when it again tries to connect , the program gets hung.
/* Published - Check if we want an acknowledgment */
if (qos > WICED_AWS_QOS_ATMOST_ONCE)
{
ret = wiced_rtos_get_semaphore(&event_semaphore, APP_AWS_PUBLISH_ACK_TIMEOUT);
if (ret != WICED_SUCCESS)
{
WPRINT_APP_INFO(("[Application/AWS] Error Receiving Publish Ack(ret: %d)\n", ret));
/* if we are still connected; Force a Disconnect */
if (is_connected)
{
wiced_aws_disconnect(aws_connection);
}
is_connected = 0;
}
}
Thanks,

I don't seem to be able to reproduce the issue that you are reporting. Can you give out your application and the steps for me to reproduce the issue?
