The Modbus master code is pretty much the same as the example which is included in the ESP IDF, i just changed a few minor things.
My application runs a few tasks in parallel if that matters, which is a websocket/webserver, modbus client, modbus server and mqtt.
- void app_main()
- {
- const static char *TAG = "main";
- esp_err_t err = nvs_flash_init();
- if (err == ESP_ERR_NVS_NO_FREE_PAGES || err == ESP_ERR_NVS_NEW_VERSION_FOUND)
- {
- // NVS partition was truncated and needs to be erased
- // Retry nvs_flash_init
- ESP_ERROR_CHECK(nvs_flash_erase());
- err = nvs_flash_init();
- }
- ESP_ERROR_CHECK(err);
- wifi_app_main();
- led_setup();
- ws_server_start();
- xTaskCreate(&nvs_main, "nvs_main", 2000, NULL, 9, NULL);
- xTaskCreate(&server_task, "server_task", 2000, NULL, 9, NULL);
- xTaskCreate(&server_handle_task, "server_handle_task", 4000, NULL, 6, NULL);
- xTaskCreate(&count_task, "count_task", 2000, NULL, 2, NULL);
- xTaskCreate(&mb_master_main, "mb_master_main", 3500, NULL, 9, &mb_master_main_th);
- xTaskCreate(&mb_slave_main, "mb_slave_main", 3500, NULL, 9, NULL);
- xTaskCreate(&mqtt_ssl_main, "mqtt_ssl_main", 1024 * 8, NULL, 9, &mqtt_ssl_main_th);
- }
(I am a beginner with ESP IDF)
