RTOS的示例程序里面分别有STA和AP的示例，由于项目需要，要是用STA+AP工作模式；

之前将STA和AP的参数放在一起定义，导致一直只能启动STA；分开单独定义即可。

STA和AP参数定义

wifi_config_t wifi_config_ap = {

.ap = {

.ssid = EXAMPLE_ESP_WIFI_SSID,

.ssid_len = strlen(EXAMPLE_ESP_WIFI_SSID),

.password = EXAMPLE_ESP_WIFI_PASS,

.max_connection = EXAMPLE_MAX_STA_CONN,

.authmode = WIFI_AUTH_WPA_WPA2_PSK

},

};

wifi_config_t wifi_config_sta = {

.sta = {

.ssid = WIFI_SSID,

.password = WIFI_PASS

},

};

WiFi初始化

void wifi_init()

{

tcpip_adapter_init();

ESP_ERROR_CHECK(esp_event_loop_create_default());

wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();

ESP_ERROR_CHECK(esp_wifi_init(&cfg));

ESP_ERROR_CHECK(esp_event_handler_register(WIFI_EVENT, ESP_EVENT_ANY_ID, &wifi_event_handler, NULL));

if (strlen(EXAMPLE_ESP_WIFI_PASS) == 0) {

wifi_config_ap.ap.authmode = WIFI_AUTH_OPEN;

}

if (strlen((char *)wifi_config_sta.sta.password)) {

wifi_config_sta.sta.threshold.authmode = WIFI_AUTH_WPA2_PSK;

}

ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_APSTA));

ESP_ERROR_CHECK(esp_wifi_start());

ESP_ERROR_CHECK(esp_wifi_set_config(ESP_IF_WIFI_STA, &wifi_config_sta));

ESP_ERROR_CHECK(esp_wifi_set_config(ESP_IF_WIFI_AP, &wifi_config_ap));

ESP_LOGI(TAG, "wifi_init_softap&sta finished.AP->SSID:%s password:%s\tSTA->SSID:%s password:%s",EXAMPLE_ESP_WIFI_SSID, EXAMPLE_ESP_WIFI_PASS,WIFI_SSID, WIFI_PASS);

}

所有WiFi状态处理在wifi_event_handler(void* arg, esp_event_base_t event_base,int32_t event_id, void* event_data)函数中处理即可

wifi事件定义(esp_wifi_types.h)
