I created a function in wifi.c that receives a pointer. The pointer would work like a traffic light and, if there was a WiFi connection, its value would change to 1. The function was called in the main function app_main(), which passes the address of the pointer. But for some reason the function is ...

I need to ensure that the code only progresses if the Wi-Fi is connected https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/wifi.html#wifi-programming-model The WiFi stack uses the default event loop to publish events like DISCONNECT or GOT_IP to the application. If you want to ...

Hello friends, how are you? I can't check if the wifi is connected, even though it is connected. My main routine is basically: void app_main(void) { // initialization SPIFFS // initialization NVS wifi_event_group = xEventGroupCreate(); ESP_LOGI(TAG, "ESP_WIFI_MODE_STA"); wifi_init_sta(wifi_ssid, wif...

Hello friends! My problem remains unresolved, so I decided to post it on espressif's github. To follow just follow the link: https://github.com/espressif/esp-idf/issues/12121

1. If your code doesn't progress to after xEventGroupWaitBits you need to double check that a) xEventGroupSetBits is actually called on the event group you're waiting on and b) xEventGroupSetBits actually sets at least one of the bits you give to xEventGroupWaitBits. In your case, the press of a bu...

But for some reason, the condition... is not satisfied. The reason is that xTicksToWait = 1000 / portTICK_PERIOD_MS causes txEventGroupWaitBits to time out and return after 1 second when no even bits are set. And you want to pass xClearOnExit as pdTRUE to the function, else the bits never get clear...

Since the issue was not resolved, I made another change. The code needs to go to the switch and wait for the user to press the button. So I changed portMAX_DELAY by xTickToWait const TickType_t xTicksToWait = 1000 / portTICK_PERIOD_MS; EventBits_t uxBits = xEventGroupWaitBits(s_wifi_event_group, WIF...

Hello ESP_Sprite! Thanks for the answer! Yes, the bits are set in the function: static void event_handler(void* arg, esp_event_base_t event_base, int32_t event_id, void* event_data) { if (event_base == WIFI_EVENT && event_id == WIFI_EVENT_STA_START) { esp_wifi_connect(); } else if (event_base == WI...

Well, to start with, do you have any function that sets those event group bits? If you don't, the task will never proceed past that. Hello ESP_Sprite! Thanks for the answer! Yes, the bits are set in the function: static void event_handler(void* arg, esp_event_base_t event_base, int32_t event_id, vo...

Hello makers! My code does not go forward after function EventBits_t bits = xEventGroupWaitBits(s_wifi_event_group, WIFI_CONNECTED_BIT | WIFI_FAIL_BIT, pdFALSE, pdFALSE, portMAX_DELAY); Everything seems to be going well, the device receives an IP and is connected to WI-FI. The function runs, returns...
