Does this project work for the STM32H753, i dont see anything in idf monitor :(

Good job!!!

Gracias por los vídeos. Thank You.

HI can you do a video on how to use images stored from spiffs and display it using lvgl decoder in esp32s3 device pls

Love all the videos on the channel, covers these topics in sequence in great depth. Love these for learning! Are there any other channels you would suggest for ESP-IDF based development with similar similar content?

How to subscribe to a topics? In AWS IOT!!!

Please provide code

Thank you!

Hi, thank you for your code! I have extended the Code so that the client can connect to a BLE server and that works! Now I want to read and write to its UUIDs, but I can't do it and have been stuck for weeks. Have you ever done this and could you give me tips on how to access the server's UUIDs read/write?

hi i use esp-idf + php+mysql +xampp (local host) +http but i can't upload data to mysql . what wrong with me . what should i do static void http_get_task() { esp_http_client_config_t config_post = { .url = "192.168.56.1/final/updateHX711data_and_recordtable.php", .method = HTTP_METHOD_POST, .cert_pem = NULL, .event_handler = _http_event_handler}; esp_http_client_handle_t client = esp_http_client_init(&config_post); char post_data[256]; snprintf(post_data, sizeof(post_data), "id=esp8266_01&&weight=10.6&status_read_sensor_hx711=SUCCESS&led_01=ON&led_02=OFF"); ESP_LOGI(TAG,"postdata: %s",post_data); esp_http_client_set_post_field(client, post_data, strlen(post_data)); esp_http_client_set_header(client, "Content-Type", "application/x-www-form-urlencoded"); esp_http_client_perform(client); esp_http_client_cleanup(client);

I love you! Got my post receiving function to work so easily that I cant even believe it!!!!! If I won the lottery, I'd give you 15%

Trying to use esp_websocket_client using idf 5.3.1 but not connecting to server. Using nodejs websocket library for server. Can connect to server using postman as client but can not with esp32 as client. I see you used postman as a server. I will try that next.

Great work, thanks for helping. Excellent (please boost your audio friend).

Could you make or send a video, how works MTLS to MQTT bruker.

How I fix it ? " E (2683) esp_https_server: No Server certificate supplied" and if you can shere exakt this code you run it.

Can you make one for mutex smaphore

can I have the code ?

Can I separate this code for server and client and run it on two esp32 boards?

The title says ESP-IDF, but isn't this really VS-Code/PlatformIO + IDF Plugin? The actual ESP-IDF is the Eclipse based tool? What would be needed for this project to build/debug under ESP-IDF/Eclipse? BTW, what's the limits as to the kinds of web-elements the ESP32 webserver deliver? For example, I assume audio/video is out.. but can it do things like CSS? (I'd like for the ESP32 to push (via websockets) ADC data, while all the connected browser clients can command LED toggles using uiverse io's switches )

היי, קודם כל הסרטונים שלך מעולים יש לי פרוייקט שבו אני צריך להשתמש במצלמה של הESP ואני לא מצליח, אני אשמח אם תוכל לעזור לי בזה ולהגיע אליך אפילו בתשלום לעזרה בנשוא

Great explanation

Really excellent introduction to freeRTOS, good job

Running similar code on my computer, the task does take the semaphore before main can. Is this a processor dependent thing?

👍🏼🇧🇷

Thanks for video. Esp-modbus hard to understand. I struggle in 1 month but not complete understand.

How can I install the ESP IDF version 5.0

how can I evaluate the consol input or create a custom command?

Modern programming - copy/paste 🙉

Thanks so much, I spent weeks trying to get a json object from the server, but your code fixed it, very grateful!

Does this no longer work in the newer versions of espressif?

Hi. I'm currently working on a project based on a WT32-eth01 and I would like to ping a specified address using the Ethernet port (as you have done in this useful video). I noticed that there is not much documentation involving the Ethernet connection as many libraries are designed to work with the WiFi module. Because of this I'd kindly ask you how to make this work on WT-eth01. I tried a lot, but at the end I get a ping error=0. Following up are most of the modification I tried to make it work: - stopping the DHCP client (assuming you enabled this service as I didn't notice the declaration of a static IP, SN, GW) - assigning a static IP, Subnet mask and default Gateway. - changing the pins as stated in the *Unofficial Guide to the WT32-eth01* including setting pin 16 High to power the port. - Enabling the 50MHz signal on GPIO0 via menuconfig (I'm using PlatformI in case it can be relevant) Knowing this is a lot of text, I want to thank you in advance for your consideration.

Hello, I am trying to do the same thing you are but when I try to post I being told "Permission denied on resource project SmartIrrigationFireStore."

You can explain an example of how can I to use vTaskSuspend() and vTaskResume()

Thank you for your video! One question. Would be possible to send something like a script? A mycropython script for instance?

Hey, got inspired and bought the board with the downloader chip to use it as a network port tester. Being a noob, I followed instructions to the t, however I just cant seem to get any thing uplaoded to the board via arduino ide. The compilation goes through fine, it just shows connecting and then gives fatal error - no serial data received even though i have the ch340 drivers installed and right com port selected in the ide. I have switched cables microusb/usb c, tried different ssequences of boot and rst key holds and press . nothing worked. can you please help me. Thanks in advance.

Very useful, thank you!

appreciated your content. I am about 6 hours into my ESP-IDF journey. Can you do something along the lines of this video: ruclips.net/video/pL3dhGtmcMY/видео.html

hello,I needed the wifi part of the code,when i upload and open serial monitor the first time handlers were working and i saw wifi messages ,but after i retried another day it doesnt work and i didnt change anything,what to do?

so you are using the FatFs library with the onboard memory from the esp32(4mb), but you could actually apply the same concept to formating an sd card and using it with an sd card reader if I understand(those arduino card readers)

i have question please, i want to read the temperature from sensor and what i have only my home wlan and Esp32.Can i connect to the free hivemq broker without caring about Certificate or public key? Second question when i connect to my university brokker i made while(1) and the inside it i put the publish call, but i always get problems with that not showing anything only error massage with connecting to Brokker, but it connected successfully

FreeRTOS SPI 인터페이스를 공부하는데 매우 도움이 많이 되었습니다. 감사합니다.

Thanks for your efforts! This was helpful... hard to find ESP-IDF tutorials and finding myself in a sea of acronyms being new to networking, which detracts from my learning

Thank you so much for these good video series. Why is necessary to add a vTaskDelay() before post_rest_function()? Is it wifi_connection() a non-blocking function?

using the name cacert.pem gave me an error, but it worked fine when I switched to servercert.pem. thanks a lot!

Could you go through BLE codes that are compatible with C++?

Me da un error de BLE_Init aguien sabe como solucionar

I will ask you something now. I will send data from another processor to ESP32 with UART using the spiffs system and write it to flash. Then I will read the data from flash by sending a command. I will use this method for the vending machine. I use esp32-wroom-32d 16mb flash to record data for months. That is, I will save the data to memory using it as my file system. # Name, Type, SubType, Offset, Size, Flags # Note: if you have increased the bootloader size, make sure to update the offsets to avoid overlap nvs, data, nvs, 0x9000, 0x6000, phy_init, data, phy, 0xf000, 0x1000, factory, app, factory, 0x10000, 1M, storage, data, spiffs, 0x110000, 0xD00000, I set the table like this and allocated 14 MB of space for spiffs. But I have a question, some people on RUclips say that you need to load the spiffs.bin file externally via pytool.py. I will not save the data I have already prepared as a user to flash and read it. I will communicate with the uart from another processor and record in that way. So this is mine. In this case, I do not need to install the spiff.bin file externally to esp32.

Great example! Any ideas on where to get the NimBLE libraries from for the EspressIF device? As mine won't compile...

fatal error: FreeRTOS.h: No such file or directory 2 | #include "FreeRTOS.h" | ^~~~~~~~~~~~ compilation terminated. How to fix this error?

man you are the best doing idf projects thank you!
