Espressif SoC revision.

ESP32-S3

Operating System used.

None

Development Kit.

Custom board

Power Supply used.

USB

What is the expected behavior?

Use both BT an MQTT

What is the actual behavior?

If I init bluetooth MQTT will crash the esp32

Steps to reproduce.

If I init BT it will work fine, but when I try to init the MQTT it will crash. MQTT alone works fine.

void bluetooth_init() {
    ESP_ERROR_CHECK(esp_bt_controller_mem_release(ESP_BT_MODE_CLASSIC_BT));
    esp_bt_controller_config_t bt_cfg = BT_CONTROLLER_INIT_CONFIG_DEFAULT();
    ESP_ERROR_CHECK(esp_bt_controller_init(&bt_cfg));
    ESP_ERROR_CHECK(esp_bt_controller_enable(ESP_BT_MODE_BLE));
    ESP_ERROR_CHECK(esp_bluedroid_init());
    ESP_ERROR_CHECK(esp_bluedroid_enable());
    ESP_ERROR_CHECK(esp_ble_gap_register_callback(gap_event_handler));
    esp_ble_scan_params_t scan_params = {};
    scan_params.scan_type = BLE_SCAN_TYPE_PASSIVE;
    scan_params.own_addr_type = BLE_ADDR_TYPE_PUBLIC;
    scan_params.scan_filter_policy = BLE_SCAN_FILTER_ALLOW_ALL;
    scan_params.scan_interval = 0x50;
    scan_params.scan_window = 0x30;
    scan_params.scan_duplicate = BLE_SCAN_DUPLICATE_DISABLE;
    ESP_ERROR_CHECK(esp_ble_gap_set_scan_params(&scan_params));
}

void mqtt_app_start(void) {
    const esp_mqtt_client_config_t mqtt_cfg = {
            .broker = {
                    .address={
                            .uri = "mqtts://test:[email protected]:8883"
                    },
                    .verification={
                            .certificate = (const char *) mqtt_eclipseprojects_io_pem_start
                    }
            },
    };

    ESP_LOGI(TAG, "[APP] Free memory: %" PRIu32 " bytes", esp_get_free_heap_size());
    esp_mqtt_client_handle_t client = esp_mqtt_client_init(&mqtt_cfg);
    /* The last argument may be used to pass data to the event handler, in this example mqtt_event_handler */
    esp_mqtt_client_register_event(client, MQTT_EVENT_ANY, mqtt_event_handler, NULL);
    esp_mqtt_client_start(client);
}

More Information.

Any ideas why is this happening? Or how to resolve this

[nopnop2002]

The ESP32 chip has four MAC addresses: Station (STA), Access Point (AP), BlueTooth (BT), and Local Area Network (LAN) These can be used at the same time.

I have created a GateWay for MQTT and Bluetooth using esp32. It works correctly.

MQTT--->ESP32--->Bluetooth MQTT<---ESP32<---Bluetooth

However, I have not tried it with ESP32S3+BLE.

(EDIT) I have created a GateWay for MQTT and BLE using esp32s3. It works correctly.

MQTT--->ESP32S3--->BLE MQTT<---ESP32S3<---BLE

@AlexMihai1804 could you provide the logs for the crash and a decoded backtrace, so I can try to identify the issue? Even better if you can provide a reproducer.

[euripedesrocha]

@AlexMihai1804 I'm closing this one, feel free to reopen, adding the reproducer.
