使用ESP32-S3开发的产品,设备开机连接路由器正常,然后断电关机,重新开机连接,这样反复测试,经常会遇到连不到路由器的情况(将设备贴近路由器也是一样的效果,不是信号问题)。连接异常时,将SYSTEM_EVENT_STA_DISCONNECTED的异常打印出来 Code: Untitled.cpp Select allcase SYSTEM_EVEN
esp_err_tevent_handler(void*ctx,system_event_t*event){} 需要向esp_event_loop_init()传入一个专门的上下文指针,当使用wifi、以太网、IP协议栈时往往会产生事件,这些事件都会被保存在事件队列中等待收取,每个处理函数都会获取一个指向事件结构体的指针,这个指针用于描述现在队首的事件,这个事件被用联合标注:even...

We received this week 5 test units, they all work perfect, except one of them is never getting the IP event so it doesn't have internet connection. Same HW, same SW, same programming method, etc. Looking at the PCB there is no sign of bad solder or anything different from the other...

* SYSTEM_EVENT_STA_GOT_IP:直译过来就是获取到IP,在进入到这个标志时,表示esp32 已经成功连接到路由器中,并被分配了IP。* SYSTEM_EVENT_STA_DISCONNECTED:wifi连接断开,在这里面需要连接wifi,重新联网。*/staticesp_err_tevent_handler(void*ctx,system_event_t*event){switch(event->event_id){caseSYSTEM_...
xEventGroupSetBits(wifi_event_group, ESPTOUCH_DONE_BIT); 1 注意点②:在esp_event_loop_init()设置的回调事件,是一个设置轮询在回调的方法,在其的方法回调中,拦截了三个状态:SYSTEM_EVENT_STA_START、SYSTEM_EVENT_STA_GOT_IP和SYSTEM_EVENT_STA_DISCONNECTED,后面的系统断开连接回调,估计只是为了适配这个demo...
WiFi.onEvent(WiFiGotIp, SYSTEM_EVENT_AP_STA_GOT_IP6); WiFi.softAP("MyESP32AP"); } WiFiApStarted函数的实现将非常简单。我们将通过在WiFi外部变量上调用softAPenableIpV6方法来启用 IPv6 支持。此方法不带任何参数。 voidWiFiApStarted(WiFiEvent_t event, WiFiEventInfo_t info){ ...

One of the members of the union is called got_ip and it contains the information about the SYSTEM_EVENT_STA_GOT_IP event. The got_ip union member corresponds to a struct of type system_event_sta_got_ip_t. You can check it here. This struct contains a member called ip_info, which ...
