Thank you! Appreciate your comment 😊

[@ChristianGrumbeck]

Thanks for this video you have no idea how much you have helped me, just thanks.

[@joedgoh]

Glad to be of help 🙂

[@МаксимТарабцев]

Thankyou very much! I, it seems, did according to your project about 5 years ago and now i found it again, but already on a new controller and it already works!

Hi there, loved your educational series. I have a question for you. What is the best solution for communicating with 60 different identities Esp32 via Wi-Fi ?

[@kevintsilvers]

Great Job

[@arunc.a2821]

You never disappoint me

[@joedgoh]

Thank you!

[@alaingoyette7103]

Hi Joed, thx for the great video. Question, do you know what is the range when using WebServer SAP? Thx!

[@joedgoh]

Thanks. It depends on the model and antenna, and other factors like walls or open area. Typically 50 meters up to 200m

[@alaingoyette7103]

@@joedgohWhat about as an Access Point? 6 to 10 meters? It's possible I get the terminology wrong 😅

[@evelioexcellenta7652]

Hello im new to this, i see that you are not using AsyncWebServer and SPIFFS, may i ask what's the difference and which one should i use (your video or these 2)? because my teacher told me to use AsyncWebServer and SPIFFS. but from your video i can't seem to see the difference in function of using your method and my teacher's method, it seems to have the same output

I've just started to learn ESP32. I've been building projects with Arduino for year, but it was time to move up to something more powerful. I'd like to confirm something that I've noticed and been able to confirm what's causing it. I watched the video and what I'm seeing here on 2 different ESP32 boards (one is 32 pin, the other a 38 pin) is different. I edited my orig comment to make it shorter. Long story short, what I see with my 2 boards, is the moment that *WiFi.mode( WIFI_MODE_STA )* is executed in setup, the Blue onboard LED is on constantly. Actually, it flickers super fast and even though no more code is executed, the light stays on (like super fast data transfer). I also confirmed that it's NOT related to Serial as I disabled all of that. In my test sketch, to confirm what I'm seeing, I started sta, waited 10 seconds then *WiFi.mode( WIFI_MODE_NULL )* to stop WiFi. *The LED goes out and functions normally.* I figured that since everything seems to run ok, this must be an indicator that WiFi mode is set. And yes, any of the mode functions have the same effect, except, Null, of course. *But in seeing the video*, I see that *WiFi.mode( WIFI_MODE_STA )* is executed in setup, but the Blue onboard LED does NOT light up and go nuts. So now I wonder, do I have a problem here? Is this a library problem or could it be a firmware issue on the 2 different ESP32 boards?? As I'm new to ESP32, I'm not where to find the right firmware files to update them or even how to see which firmware version they currently have. So can anyone confirm if this is a problem or if it's just how some ESP32 boards work? I should say that one of them has the word, WROOM on it and supposedly it's: *ESP-WROOM-32 Chip CP2102* (38 pins) The other one says, *ESP32-D0WDQ6 Chip for IOT.* (30 pins) So as far as I can tell, they are different, yet with the WiFi mode set, they both have the Blue LED steady on. Does anyone know?? Thanks in advance.

Totally new to ESP32 how easy would this be to use toggle buttons instead of standard button?

[@sachintharavindu3356]

I need some help. The server can be accessed by clients on the local area network, but how can I deploy it to be accessed by my devices anywhere on earth through the internet? is there restrictions on the ESP to achieve this?

[@joedgoh]

the remaining lessons will answer your question.

[@rianriansct]

Hi, is it possible if in 1 wifi network I want control or remote 3 Unit ESP32 using web server?

[@saurabhjoglekar]

Yes, they all will have different IP addresses and you can each device's webpage by inputting that IP address. One issue you will encounter is that you will not know which IP addess is which device. You solve it by having your WiFi router to "Bind" each device to a separate IP address. That way each device will get same IP whenever they connect to the wifi.

[@growingscoville]

Hi sir, ask ko lang kung meron ka po bang uploaded video na timer switch for light.

Wala pa po. Can you give the expected behavior nung "timer switch for light" na hinahanap mo?

[@killergriller87]

Wow this is really damn well explained, thank you very much. This is perfect for my model building. I have a question can you also store a picture, because as far as I know the esp32 can not do that, but maybe I'm wrong.

[@joedgoh]

Yes you can store images to the flash file system. You can search on SPIFFS and AsyncWebServer. Thanks!
