Connect ESP32 to WiFi (ESP32 + Arduino series)

Learn how to connect your ESP32 to your WiFi network. This is the biggest advantage of the ESP32: built-in WiFi.

Once you have a WiFi connection, you can use it to send data to internet services such as ThingSpeak, AWS IoT, ...

Thanks for saving everyone's time in giving such a precise explanation.
And helping everyone by not giving the script and making them learn.

You’ve chosen the perfect name for your channel, even I understood it.

Schitterende video, erg goed uitgelegd. Dan nog wel van België!!! Congratz!

I liked the way you presented the Code. I recommend you to post more of such videos. For example for ESP 32 RFID | GSM | GPS etc.

Thank you for this EXCELLENT introduction to ESP32 wifi. Your explanation is super clear and easy to follow. Thank you for sharing your knowledge.

[kbruin]

Great and super clear tutorial. Thank you for sharing!

Thank you for the video. Is it possible to send digital data from an ESP32 with this sketch written to an ESP32 set up in APmode? For example, if I want to send a pulse or number every second.

I cannot get my ESP32 to connect using these among many other instructions/code. What settings does the wifi router need to be on? My conclusion is it must be the router that's causing the ESP32 to not connect.

Good day, please what C plus plus extension created the folder directory like that? With the lib, test and src folders

[baxter]

Very well explained. I wish the standard BSD sockets could've been designed and implemented as cleanly.

i just watched another one of these vids tho from a diff fella. this is explained better

Do you have a video or good resource for using Access Point mode to setup/change wifi credentials?

Ideally I would be able to put my esp32 into a configuration mode and connect to it with my phone or pc to configure the wifi settings somehow. (preferably something really easy so anyone can do it.) then when I reset the esp32 it tried to use the credentials it was given.

Thanks!

How to access/use the wifi ip address on mobile or laptop. What we can with this ip

[shikharsingh]

I have a quick question. On your serial monitor before displaying 'Connecting to a bunch of random characters are displayed. Why does this happen? The same thing happened when I tried your code from my side and when I changed the baud rate to 115200 nothing but random characters were displayed. The board did manage to connect to my wifi network regardless of the baud rate. Can you explain why these random characters are displayed and if there is some way to stop them from showing up?

What could you do if you wanted to connect an AVR ATmega328p (Arduino UNO) to WiFi ?

[OrientalStories]

[randyjavierpenaloflorian]

Can you change the channel in the wifi with the arduino IDE?
