本文讨论了ESP32在STA+AP模式下无法上网的问题。通过详细的代码示例，展示了如何配置ESP32的WiFi模式、SSID和密码。具体步骤包括初始化WiFi、设置STA和AP模式的配置参数，并确保连接成功。最终目标是使ESP32能够同时连接到路由器并通过AP提供网络服务。

设置esp32模式sta+ap sta连接路由器，手机连接ap后无法上网。 请问需要怎么编码？ [mw_shl_code=c,true]#include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "freertos/event_groups.h" #include "esp_system.h" #include "esp_wifi.h" #include "esp_event_loop.h" #include "esp_log.h" #include "nvs_flash.h" #define WIFI_SSID "KKKKg" #define WIFI_PASS "123456zzz" static const char *TAG = "espressif"; /* FreeRTOS event group to signal when we are connected & ready to make a request */ static EventGroupHandle_t wifi_event_group; /* The event group allows multiple bits for each event, but we only care about one event - are we connected to the AP with an IP? */ const int CONNECTED_BIT = BIT0; static esp_err_t event_handler(void *ctx, system_event_t event) { switch (event->event_id) { case SYSTEM_EVENT_STA_START: esp_wifi_connect(); break; case SYSTEM_EVENT_STA_GOT_IP: xEventGroupSetBits(wifi_event_group, CONNECTED_BIT); break; case SYSTEM_EVENT_STA_DISCONNECTED: / This is a workaround as ESP32 WiFi libs don't currently auto-reassociate. */ esp_wifi_connect(); xEventGroupClearBits(wifi_event_group, CONNECTED_BIT); break; default: break; } return ESP_OK; } static void initialise_wifi(void) { tcpip_adapter_init(); wifi_event_group = xEventGroupCreate(); ESP_ERROR_CHECK( esp_event_loop_init(event_handler, NULL) ); wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT(); ESP_ERROR_CHECK( esp_wifi_init(&cfg) ); ESP_ERROR_CHECK( esp_wifi_set_storage(WIFI_STORAGE_RAM) ); wifi_config_t sta_wifi_config = { .sta = { .ssid = WIFI_SSID, .password = WIFI_PASS, }, }; wifi_config_t ap_wifi_config = { .ap = { .ssid = "esp32_ap", .password = "xj123456", .authmode = WIFI_AUTH_WPA_WPA2_PSK, .max_connection = 3, }, }; ESP_LOGI(TAG, "Setting WiFi configuration SSID %s...", sta_wifi_config.sta.ssid); ESP_ERROR_CHECK( esp_wifi_set_mode(WIFI_MODE_APSTA) ); ESP_ERROR_CHECK( esp_wifi_set_config(ESP_IF_WIFI_STA, &sta_wifi_config) ); ESP_ERROR_CHECK( esp_wifi_set_config(ESP_IF_WIFI_AP, &ap_wifi_config) ); ESP_ERROR_CHECK( esp_wifi_start() ); } void app_main() { ESP_ERROR_CHECK(nvs_flash_init()); initialise_wifi(); }[/mw_shl_code]   |
我同时看了乐鑫的Q&A，表明8266在sta+ap模式下，硬件是单信道。所以是有问题的。从测试效果来看esp32也是AP无法上网。估计esp32也是单信道。硬件上不支持吧。这样就把sta+ap模式价值大打折扣了
