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.

Based on a Nordic Semiconductor 32-bit ARM system-on-chip that has built-in support for Bluetooth 4.0, the RFduino runs the same code as Arduino UNO and DUE boards, and it works with any type of ...

The Arduino 101* Bluetooth® LE is based on the Generic Attribute Profile (GATT) architecture. GATT defines a hierarchical data structure that is exposed to connected Bluetooth® LE devices.

The Coin Arduino-BLE kit is designed to simply that by offering a pre-rolled solution, completely with open-source software that will go up on Github in December, which is when the boards should ship.

“You can upload your code without USB cable. It is wireless by Bluetooth. Yes, once you have Bluetooth on you computer, you can update the Z-duino over the air.

Whether you’d like to do some real-time logging of data, or just want to control a project with your Android phone, [Thomas]’s Arduino-Android Bluetooth connection instructable is sure … ...

Primo will include Bluetooth LE (low energy), NFC, Wi-Fi, and infrared built-in — you typically need a “shield” add-on to get these features.

The watch is built around an Arduino Pro Mini, a scavenged Nokia LCD, and a BlueSMiRF Gold. The Bluetooth connects to a Nokia N900 with a little Bluetooth client app [Ahmet] wrote.

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...

Arduino Nano 33 BLE Sense is a nano-sized board with Bluetooth connectivity and well equipped with sensors which include a 9-axis inertial measurement unit (IMU) which adds a compass to the usual ...
