Sync problems between threads

The original code stops at:

[APP] Startup.. [APP] Free memory: 262052 bytes [APP] SDK version: 1.0.0(3e67f0f), Build time: 2016-Nov-04_10:46:54_EET [APP] Start, connect to Wifi network: Shirkan .. /work/esp32/esp-idf/components/freertos/./queue.c:716 (xQueueGenericSend)- assert failed! Guru Meditation Error: Core 0 panic'ed (Unhandled debug exception)

due to unsynchronized threads for connect and mqtt

the following changes resolved the issue for me: I used the 'original' startup / wifi connect code from the esp-idf samples (here: 03-http) and added a sync so the mqtt thread does not start before the network is set up properly:

void app_main()
{
    nvs_flash_init();
    system_init();
    initialise_wifi();
    //xTaskCreate(&http_get_task, "http_get_task", 2048, NULL, 5, NULL);
    /* Wait for the callback to set the CONNECTED_BIT in the
       event group.
    */
    xEventGroupWaitBits(wifi_event_group, CONNECTED_BIT,
                        false, true, portMAX_DELAY);
    ESP_LOGI(TAG, "Connected to AP");

    // Notice that, all callback will called in mqtt_task
    // All function publish, subscribe
    mqtt_start(&settings);

}
