Getting Started with ESP32 Bluetooth Low Energy (BLE) on Arduino IDE

The ESP32 comes not only with Wi-Fi but also with Bluetooth and Bluetooth Low Energy (BLE). This post is a quick introduction to BLE with the ESP32. First, we'll explore what's BLE and what it can be used for, and then we'll take a look at some examples with the ESP32 using Arduino IDE. For a simple introduction we'll create an ESP32 BLE server, and an ESP32 BLE scanner to find that server.

Hey could you make a tutorial on Bluetooth serial communication on esp32

Boas Rui, sabes se já existe alguma coisa para enviar URL por ESP, seria algo de Broadcast.

Hello, love your tutorials, can you help with a small project. I want my esp32 to connect to the cycling program called "zwift" as a fitness machine. Ftms? And then receive the resistance characteristic value and serial.print the value. I have been trying for ages. Just need a start off to get going. Thanks for any help

Hi! Do you know any method to limit on the server the number of incomming connections (clients) to one? Thank you.

Dear Rui, Greetings. I am working on ESP32 module for one of my BLE projects. I used the BLE server sketch that was in one of your tutorials, and tried connecting the server to a android NRF phone client. It worked fine. BLE device name was available within the client. I was also able to read characteristics too, But the same experiment, if i tried executing in my house, the connection does not get established. I really dont know regarding this issue. Kindly advise in this regard.

I'm going to refer to your link to get more information

I'm trying to use a BluetoothBLE (ESP32) to receive audio and some info on the tracks from a mobile phone, I can't seem to get the audio streaming working, and I can't get it to work with IOS at all, do you have any ideas?

Do you have example about BLE broadcast ? thanks a lot

Will this wrk as Ble Midi controller????

Question - I am unable to get the name displaying in the scan example. I know there is a bug regarding this however do you have a work around? I am able to see Esp32 in a phone Bluetooth app but not on the ESP32.

Hi! Do you know if you can change the name of the bluetooth so that it appears as we want, when looking for it with another device?
