Problem with multiple MQTT messages sent to MESH_NODE.

Posted: Wed Sep 18, 2024 2:16 am

I am working on a ESP32 MQTT5 WiFi Mesh project using IDF. I am running the same software in my MESH_ROOT as I am in my MESH_NODE both using ESP-32-S3, with a Mosquito broker on a local LAN PC.

I am finding if my client Host (PC App) sends some medium size payloads eg around 420 bytes in quick succession to a MESH_NODE, the first packet is received and responded to by my application, but I don't get a MQTT_EVENT_PUBLISHED event for my response and I don't receive the rest of the published messages.
I can see the response message continues to be resent at 1 second intervals (as we are not getting the Publish Ack from the broker).

Also when this happens I get a matching number of the following messages on my MESH_ROOT

  1. E (13:51:38.630) mesh_netif: Send with err code 16392 ESP_ERR_MESH_ARGUMENT

Eventually my MESH_NODE times out and disconnects from the broker and reconnects after which communications are restored. So its like the Host client MQTT messages overload the MQTT receiver and I lose connection with the broker.

If I add a 200mSec delay between messages published by my client Host app, they are all received and responded to correctly. I don't need this delay when sending to my MESH_ROOT.

I don't mind the 200mS delay, but I am concerned my delays at the Host client app will be washed out by the trip to the broker and then to the ESP32 MESH_ROOT and on to the target ESP32 MESH_NODE

I have streamlined my processing on the MQTT_EVENT_DATA event to simply stack the received message topic, payload, responsetopic and correlationdata into a vector as follows and process it and respond back from another task.

Code: Select all

[Codebox=cpp file=Untitled.cpp]    case MQTT_EVENT_DATA: {
        // ESP_LOGD(TAG, "MQTT_EVENT_DATA");
        // print_user_property(event->property->user_property);
        // if (event->property->content_type_len > 0 ) ESP_LOGI(TAG, "content_type: %.*s", event->property->content_type_len, event->property->content_type); // not sure what this is yet
        inBoxClass inBoxrecord = {};
        inBoxrecord.topic.assign(event->topic, event->topic + event->topic_len);
        inBoxrecord.payload.assign(event->data, event->data + event->data_len);
        inBoxrecord.responseTopic.assign(event->property->response_topic, event->property->response_topic + event->property->response_topic_len);
        inBoxrecord.correlationData.assign(event->property->correlation_data, event->property->correlation_data + event->property->correlation_data_len);
        MQTTInBoxMutex.lock();
        inBoxList.push_back(inBoxrecord); // queue into our InBox
        MQTTInBoxMutex.unlock();
        break;
    }
[/Codebox]
Are there some buffers I could increase the size or number of to fix this?

I found esp_wifi_init(&config) the config struct has a number of buffer sounding elements, so I tried increasing the ones which sounded buffer-like and were small as follows:
Code: [Select all] [Expand/Collapse]
  1.     wifi_init_config_t config = WIFI_INIT_CONFIG_DEFAULT();
  2.     config.tx_hetb_queue_num = 20;
  3.     config.rx_mgmt_buf_num = 20;
  4.     config.cache_tx_buf_num = 20;
  5.     config.static_tx_buf_num = 20;

But this did not help. I also tried increasing the mqtt5_cfg.buffer.size to 10,000 but no change.

Here is a failed run with no inter-message delay. See MQTT_EVENTS event_id=6, my INBOX with the message received, the esp_mqtt_client_enqueue with my response, No MQTT_EVENT_PUBLISHED event. A minute later we log a broker disconnect and reconnect and then everything is restored
