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.

This shield could be a good alternative to hobby RC controllers for robots that need a customizable open-source motor controller. The PCB design and source code are available on GitHub.

The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!.

– An all-in-one motor shield, Bluetooth shield, Wi-Fi shield, sensor shield and a wireless programming shield compatible with Arduino UNO,stm32 nucleo, Mega and Renesas (GR-Peach).
