[paho-dev] ESP-IDF - Subscribe and Yield

[Hitesh Pratyush V <hiteshpratyush@xxxxxxxxx>]

I am working on making a subscriber code to run on my ESP32. I am able to connect to my broker and I am able to subscribe as well but I am unable to receive the messages that are being sent to the Device and as a result the broker keeps sending messages to the device. Even when I receive the message, the ACK is not being sent back.

https://github.com/eclipse/paho.mqtt.embedded-c 

This is link to the code Client API that I am using but there is not proper documentation to help me out.

ESP_LOGI(MQTT_TAG, "MQTTUnsubscribe  ...");

ret = MQTTUnsubscribe(&client, "test/topic");

if (ret != SUCCESS) {

ESP_LOGI(MQTT_TAG, "MQTTUnsubscribe: %d", ret);

}

This is the code to subscribe.

while(1) {

ret = MQTTYield(&client, 1000);

if (ret != SUCCESS) {

ESP_LOGI(MQTT_TAG, "MQTTYield: %d", ret);

}

}

And this is the code to keep the client connection alive.

It would be great if someone could help me out 
I also posted an issue on Github at the link https://github.com/eclipse/paho.mqtt.embedded-c/issues/138
If someone knows something you can help me out on the link above. 

Thank You.
