This was very interesting and needed. Moving from microcontroller that do not have protocols to the esp32 I am having to learn networking and protocols to get the most out of the chip. I am no longer limited to doing "local" projects. I took your learnESP32 course and it was fantastic. Thank you.
I started learning ESP32 a few weeks ago. Although I have been a professional Windows developer for more than 25 years and already knew the concepts of the HTTP protocol in principle, it was really interesting to follow the video and see how it is done with ESP32. The 90 minute video is a bit long, but it's worth it in my opinion. The topics are well selected and clearly explained so that you can start your own excursion. Thank you for all the work and sharing your knowledge! Greetings from Germany
Great video, learned a lot! I have begun to work on a ESP32 project recently and this video helped me a lot in developing it. I have a question, at 57:12 , what is the difference between the certificates mentioned in the given hierarchy. When should one use a particular certificate in the ESP32 application?
I want to send data to the localhost server frm esp32 but I am getting error like this E (4528) esp-tls: [sock=54] delayed connect error: Connection reset by peer E (4528) TRANSPORT_BASE: Failed to open a new connection: 32772 E (4528) HTTP_CLIENT: Connection failed, sock < 0 What is the solution for it?
is there any configuration should be done in the sdkconfig file for the http client example? because it didn't work for me. not even the https client but the http server worked. Also the example provided by espressif isn't working for me although I configured my ssid and password in sdkconfig file, but i don't know if there is something else that should be done.

Love the top-down teaching approach, you clearly share the knowledge. No stress for the listener. Great tutorial.

This is a great video, thanks a lot for taking the time to make this video and share your knowledge.
Tks! This material is amazing!
I like your content explained in your video, its a bit hard to find a good content as you show here, thanks.
I was going to add that a future video on using sockets with the esp32 would very useful.
Thank you !!!!

Hi sir are there any different between https and Rest api
Hi, is it neccessary to use free function for some buffer which taken by malloc ? 19:40
Yes, when you are finished with the data that is something you would want to do
24:04 I couldnt follow you because after upload the terminal to nothing :/ I dont know how i must work with makefiles in plattformio
I want to send data to the localhost server frm esp32 but I am getting error like this
E (4528) esp-tls: [sock=54] delayed connect error: Connection reset by peer
E (4528) TRANSPORT_BASE: Failed to open a new connection: 32772
E (4528) HTTP_CLIENT: Connection failed, sock < 0
What is the solution for it?
Hi, is it possible to download a 10MB file like mp4, mjp, raw from a http website and save it into SD card?
Yes. This is possible
is there any configuration should be done in the sdkconfig file for the http client example? because it didn't work for me.
not even the https client but the http server worked.
Also the example provided by espressif isn't working for me although I configured my ssid and password in sdkconfig file, but i don't know if there is something else that should be done.
Hi Haldar. what's the error?
@@mairswartz your http client example is not giving errors, but its not reading anything from the website, the buffer string is empty.
@@mairswartz Same issue here, I'm not sure what's up.
Hello did you record some tutorials for async http too?
If you use FreeRtos the application will everything in an async manner. see ruclips.net/video/E9FY-IOvC3Q/видео.html
could you give me your slide
@yen Yuthnea, I added the pptx file to the repo. Link in the above description
Hi Mair ,i see that in the sdkconfig file, you changed the partition table with a custom one, is that mandatory ? because during running i see errors of :
I (418) cpu_start: Starting scheduler.
