Help using wifi_set_event_handler_cb with esp_open_rtos

[desha....@gmail.com]

Hi Forum,

I am new to esp-open-rtos and keen to learn how to use it.  I would like to create an example that allows me to see the state of the wifi connection.  After reading the espressif RTOS SDK I saw the wifi_set_event_handler_cb callback and I thought I would try to get an exampled working using esp-open-rtos.

However, I cannot figure out the include files to use for the System_Event_t type.  I tried user_interface.h but this go more errors, about already defined types.

Could some point me towards what include files I should use?

Please find attached the basic code I tried to comiple using make flash -j4 -C examples/test/ ESPPORT=/dev/ttyUSB0

example/test/test.c

#include "espressif/esp_common.h"

#include "esp/uart.h"

#include "FreeRTOS.h"

#include "ssid_config.h"

void broadcast_temperature(void *pvParameters)

{

    while (1){}

}

void wifi_cb(System_Event_t *evt)

{

  os_printf("event %x\n", evt->event);

  switch (evt->event) {

    case EVENT_STAMODE_CONNECTED:

        os_printf("connect to ssid %s, channel %d\n",

                evt->event_info.connected.ssid,

                evt->event_info.connected.channel);

        break;

    case EVENT_STAMODE_DISCONNECTED:

        os_printf("disconnect from ssid %s, reason %d\n",

                evt->event_info.disconnected.ssid,

                evt->event_info.disconnected.reason);

        break;

    case EVENT_STAMODE_AUTHMODE_CHANGE:

        os_printf("mode: %d -> %d\n",

                evt->event_info.auth_change.old_mode,

                evt->event_info.auth_change.new_mode);

        break;

    case EVENT_STAMODE_GOT_IP:

        os_printf("ip:" IPSTR ",mask:" IPSTR ",gw:" IPSTR,

                      IP2STR(&evt->event_info.got_ip.ip),

                      IP2STR(&evt->event_info.got_ip.mask),

                      IP2STR(&evt->event_info.got_ip.gw));

        os_printf("\n");

        break;

    default:

        break;

    }

}

void  user_init()

{

    uart_set_baud(0, 115200);

    printf("SDK version:%s\n", sdk_system_get_sdk_version());

    struct sdk_station_config config = {

        .ssid = WIFI_SSID,

        .password = WIFI_PASS,

    };

    sdk_wifi_set_opmode(STATION_MODE);

    sdk_wifi_station_set_config(&config);

    wifi_set_event_handler_cb(wifi_cb);

    xTaskCreate(&broadcast_temperature, "broadcast_temperature", 256, NULL, 2, NULL);

}

Thanks

I don't think it has a similar function. You can use sdk_wifi_station_get_connect_status to get the status and work further.
