ESP32 Bluetooth Classic - ESP32 Beginner's Guide

The ESP32 is a very powerful microcontroller with integrated WiFi and Bluetooth.
So, let's see how to use its built-in Bluetooth.

Very well explained. Thanks for taking your time to do this, appreciated.

[flaviodasilva]

Thank you. I have been trying to do this for days until I found you! Keep up the good work. You are very good at explaining. I would love it if you did a video to do the same thing you did here, but instead communicate via Bluetooth Classic with a PC using Python.

[sdouba]

Thank you for clear, yet concise instructions.

[fwjfkrb]

you explain it very nicely and in a understandable way !
Thank you

[AhmedHamdy-iklg]

Thank you so much for this and i just want to ask about using both wifi and bluetooth in the same program but there's an error indicating that I'm using 117% of the memory size

Just tried this, awesome work, love the Bluetooth app to test code, save me a heap of time.

[GaryParkin]

Thank you so much. This worked perfectly. I had to pair the phone first before going into the terminal. (I was wondering why I didn't see the devices in the Bluetooth app.).
I was able to use the external LED's we created in the last lesson. I don't yet know what I'm going to use the ESP32 for, but I'm truly surprised at what it can do.

[anabeldomenech]

you are the best..no one explain easy and fine like you...greetins from venezuela...carribbean sea...bolivar land..

[khadija]

Do you have a video that explain how to use BleScanner?

[jeantedesqui]

Very cool! I'm trying to do an anti-lost smartphone project using ESP32 and a small box that will vibrate in the person's pocket if they move away from the smartphone to the point of losing the Bluetooth connection with the ESP32. What changes should I make in this code to make my project work?

[Ravenseyes]

Can you enable Bluetooth so the ESP32 can run WLED from the app on your phone without being connected to a network?

[messix]

so does the usb wire need to be connected to the esp32 or will my solar panel will support the esp32 and eventually my sensor providing live feed to my blynk app. need help mate asap...

[farellalvaro]

what about connecting esp32 bluetooth to PC? In your case, connecting esp32 bluetooth to terminal bluetooth as slave. But what if connecting esp32 to pc (Master - master)?

[madhavdivya]

Nice video.

Got a few doubts and am looking forward to hearing from you.

What if I attempt connecting with the ESP 22 from multiple phones?

If my phone is not connected, can anyone else connect to the module from their phone?

Can I establish communication amidst a master ESP32 and two bluetooth slaves, also ESP32?

The connection amongst the 3 devices should happen only amongst themselves every time they are powered up.

Can it be done?

Conoces algun esp32 mas pequeño que este que tenga bluetooth clasico

[ikif]

How I send '1' or '0' to esp32 by Bluetooth from PC (win11) ?

[TheJavaSync]

I watched another video, ESP32 BLE micropython (& unfortunately it dioesn't work for me, my ESP32_BLE doesn't detected by my phonecell), why in Arduino it seems more simple (& hope it will work for me) 😅
Thank You!! ❤

Hi, i am beginner to esp32. I am trying to transfer file to sd card in esp32 development board using react native programming. is there any process to do so without any ftp or TCP or web server. please do guide me in this project. Thanks in advance.

[Tarou]

Excelent, but how do i know if the is no message being sent? in other words, make an action only when a message is sent

[csil]

Your video is very good and helpful. I

I used your program as a basic framework for sending a value to my phone by Bluetooth. There is nothing else in the program yet it uses 76% of the program storage space. When I try to incorporate that into another larger program, it exceeds the storage space and will not compile. Any suggestions?
