About Opinionated starter-code for web-bluetooth projects with arduino BLE serial modules.

But "Arduino Bluetooth Control" app's example code only work for Arduino board connect to an external Bluetooth module HC-05. So I modify it so it can be use on ESP32 as well.

IntroductionBluetooth® Low Energy (Bluetooth® LE or BLE) is a low-power, short-range wireless communication technology that is ideal for use on the Internet of Things (IoT). BLE is designed for ...

In this Arduino bluetooth tutorial we will connect two HC-05 bluetooth modules together using Arduino, and make them communicate using master slave configuration.

For this Arduino Bluetooth Controlled AC Project, make sure you have an Arduino Mega and not any other version of Arduino, since the code size is heavy. Install the IR Remote Library using this link ...

In Connecting to Intel® Edison from Android* with Bluetooth* LE (BLE) describes a way to access BT via Arduino code but additional BT shield/kit is required.

Thanks to the LightBlue Bean+, however, one of those roadblocks has been torn down. The Bean+ is basically an Arduino board that can be programmed via Bluetooth LE.

Arduino enthusiasts searching for a board that supports connection via Bluetooth rather than USB may be interested in the Z-duino Bluetooth Arduino board recently launched via Kickstarter.
