5 years ago Hello sumit612,
Using the latest in master as of this post. I am able to make an MQTT connection with your xConnectParameters.
I added to ESP32's aws_demo_config.h:
#define democonfigMQTT_AGENT_CONNECT_FLAGS ( mqttagentREQUIRE_TLS | mqttagentUSE_AWS_IOT_ALPN_443 )My quick and dirty code:
MQTTAgentHandle_t xMQTTClientHandle;
/* Create MQTT Client. */
if( MQTT_AGENT_Create( &( xMQTTClientHandle ) ) == eMQTTAgentSuccess )
{
MQTTAgentConnectParams_t xConnectParams =
{
clientcredentialMQTT_BROKER_ENDPOINT,
democonfigMQTT_AGENT_CONNECT_FLAGS,
pdFALSE,
clientcredentialMQTT_BROKER_PORT,
( const uint8_t * ) ( clientcredentialIOT_THING_NAME ),
( uint16_t ) strlen( ( const char * ) clientcredentialIOT_THING_NAME ),
pdFALSE,
NULL,
NULL, /* No call back not needed just to connect. */
NULL,
0
};
if( MQTT_AGENT_Connect( xMQTTClientHandle,
&xConnectParams,
pdMS_TO_TICKS( 20000UL ) ) != eMQTTAgentSuccess )
{
configPRINTF( ( "ERROR: Could not connect to the Broker.\r\n" ) );
}
else
{
if( MQTT_AGENT_Disconnect( xMQTTClientHandle,
pdMS_TO_TICKS( 20000UL ) ) == eMQTTAgentSuccess )
{
configPRINTF( ( "Disconnected from the broker.\r\n" ) );
if( MQTT_AGENT_Delete( xMQTTClientHandle ) == eMQTTAgentSuccess )
{
configPRINTF( ( "Deleted Client.\r\n" ) );
}
else
{
configPRINTF( ( "ERROR: MQTT_AGENT_Delete() Failed.\r\n" ) );
}
}
else
{
configPRINTF( ( "ERROR: Did not disconnected from the broker.\r\n" ) );
}
}
}my output:

This means some certificate verification failed somewhere down the handshake process. Please check and make sure that the keys in demos\include\aws_clientcredential_keys.h are correct and in correct format. Also that those keys are associated with your thing.

Describe the bug MQTT agent was connecting with TLS certificates in MQTT v1. After porting the same application on MQTT v2 with same connect flags( mqttagentREQUIRE_TLS | mqttagentUSE_AWS_IOT_ALPN_443 ) and credentials MQTT_AGENT_CONNECT() fails to connect with AWS broker via wifi while MQTT Demo is working fine.

Expected behavior Should connect with AWS mqtt broker
