Re: RMT transaction on led strip corrupted by WiFi interrupts

Thank you for the help. I think I found the cause of my problem. The DMA buffer size for RMT is by default too small in my case. The data frame has to break into several pieces and then extra delay caused by WiFi is then added in between the fragments. I have increased the mem_block_symbols in led_s...

Re: RMT transaction on led strip corrupted by WiFi interrupts

Hi dmitrij999, thanks for help. I am only using one RMT channel for one strip.
Workaround with SPI would be my last option if i really could not fix it with RMT.

RMT transaction on led strip corrupted by WiFi interrupts

Greetings, I am working on a project in which I use RMT of ESP32S3 to transmit data on a LED strip and WiFi for LED configuration. I have observed that some of the LEDs will flicker especially when the number of connected sockets changes in WiFi driver. And the LEDs will be much more stable if WiFi ...

Re: RGBW Support?

Hi,

This is the library that you can use: https://components.espressif.com/compon ... /led_strip

led_strip_config_t is where you can configure the driver to support RGBW.

Re: support Wi-Fi Aware (NAN) on ESP32S3

Thanks for the reply. I am aware of the document page. But the ESP-IDF (release 5.1) and the github says differently. ESP32S3 is not supported yet. https://github.com/espressif/esp-idf/blob/v5.1/components/esp_wifi/include/esp_wifi_types.h https://github.com/espressif/esp-idf/tree/v5.1/examples/wifi...

support Wi-Fi Aware (NAN) on ESP32S3

Hi, Based on what I found in ESP-IDF 5.1.3 and 5.2.1, it seems that Wi-Fi Aware or NAN (Neighbor Awareness Networking) is only supported on ESP32 and ESP32S2. See this example: https://github.com/espressif/esp-idf/tree/release/v5.2/examples/wifi/wifi_aware/nan_publisher and the code below typedef en...

大量DNS请求无法响应,导致网页加载时间太长

我在ESP32S3上写了个小程序,让WiFi开始AP模式,然后运行REST server。我是用ESP-IDF 5.1.2写的额。这是我的Main函数 void app_main(void) { nvs_flash_init(); ESP_ERROR_CHECK(esp_netif_init()); ESP_ERROR_CHECK(esp_event_loop_create_default()); initialise_mdns(); netbiosns_init(); netbiosns_set_name(CONFIG_EXAMPLE_MDNS_HOST_NAME); wifi_init_s...

extra delay when loading webpage on ESP32S3 in softAP mode

I try to create an application on ESP32S3 using ESP-IDF 5.1.2 which first starts WiFi in softAP mode and then starts a REST server. I have combined the softAP example https://github.com/espressif/esp-idf/tree/master/examples/wifi/getting_started/softAP and the REST server example https://github.com/...
