Hi everyone, I have the same problem with the latest version.
Thank you for your help

I just tried here and I've got the notification "MQTT_EVENT_DISCONNECTED" when my broker went down. Is that what you're referring to?
D (28694) MQTT_CLIENT: mqtt_enqueue id: 29690, type=3 successful
D (28714) MQTT_CLIENT: msg_type=4, msg_id=39347
D (28714) MQTT_CLIENT: pending_id=39347, pending_msg_count = 1
D (28714) MQTT_CLIENT: received MQTT_MSG_TYPE_PUBACK, finish QoS1 publish
I (28724) LOG: MQTT_EVENT_PUBLISHED, msg_id=39347
E (28954) MQTT_CLIENT: Read error or end of stream
I (28954) MQTT_CLIENT: Reconnect after 10000 ms
I (28954) LOG: MQTT_EVENT_DISCONNECTED <<<<< this is my log
Snippet of my code:
static esp_err_t mqtt_event_handler(esp_mqtt_event_handle_t event) {
switch (event->event_id) {
case MQTT_EVENT_CONNECTED:
client = event->client;
ESP_LOGI(LOG, "MQTT_EVENT_CONNECTED");
break;
case MQTT_EVENT_DISCONNECTED:
ESP_LOGI(LOG, "MQTT_EVENT_DISCONNECTED");
break;
case MQTT_EVENT_SUBSCRIBED:
ESP_LOGI(LOG, "MQTT_EVENT_SUBSCRIBED, msg_id=%d", event->msg_id);
break;
case MQTT_EVENT_UNSUBSCRIBED:
ESP_LOGI(LOG, "MQTT_EVENT_UNSUBSCRIBED, msg_id=%d", event->msg_id);
break;
case MQTT_EVENT_PUBLISHED:
ESP_LOGI(LOG, "MQTT_EVENT_PUBLISHED, msg_id=%d", event->msg_id);
break;
case MQTT_EVENT_DATA:
ESP_LOGI(LOG, "MQTT_EVENT_DATA");
printf("TOPIC=%.*s\r\n", event->topic_len, event->topic);
printf("DATA=%.*s\r\n", event->data_len, event->data);
break;
case MQTT_EVENT_ERROR:
ESP_LOGI(LOG, "MQTT_EVENT_ERROR");
break;
}
return ESP_OK;
}
And the reconnection after 10s works too:
D (76214) MQTT_CLIENT: Reconnecting...
D (81214) TRANS_TCP: [sock=56],connecting to server IP:192.168.1.92,Port:1883...
E (98774) MQTT_CLIENT: Error transport connect
I (98774) MQTT_CLIENT: Reconnect after 10000 ms
I (98774) LOG: MQTT_EVENT_DISCONNECTED
The only thing that I noticed is that even when the client is disconnected, after a fail attempt, it will rise MQTT_EVENT_DISCONNECTED again.
And when my broker was started again, my MQTT client automatically connected to it:
D (263834) MQTT_CLIENT: Reconnecting...
D (268834) TRANS_TCP: [sock=61],connecting to server IP:192.168.1.92,Port:1883...

Hi @casmeiron
It is correct what you mention.
I am using the ethernet interface, when I disconnect the interface, the mqtt client does not launch the MQTT_EVENT_DISCONNECTED event, but in the previous version after disconnecting the interface the event was launched after the 10 second timeout.
Everything else is correct.
thanks for your answer.

Hi all,
Can we close this old issue? As far as I can see MQTT_EVENT_DISCONNECTED event works as expected (will yet test it with ethernet, but don't expect any issue there)

@bengiexd just tested on ethernet and MQTT_EVENT_DISCONNECTED event received correctly. Please note that you can configure keep alive timeout (by default 120s) to any value of your preference:
esp_mqtt_client_config_t mqtt_cfg = {
.uri = "mqtt://192.168.0.111",
.event_handle = mqtt_event_handler,
.keepalive = 10,
// .user_context = (void *)your_context
};
I'm taking the liberty to close the issue, please reopen if needed.
