Bluno is first of its kind in intergrating BT 4.0 (BLE) module into Arduino Uno, making it an ideal prototyping platform for both software and hardware developers to go BLE. You will be able to develop your own smart bracelet , smart pedometer and more. Through the low-power Bluetooth 4.0 technology, real-time low energy communication can be made really easy. 

Bluno integrates a TI CC2540 BT 4.0 chip with the Arduino UNO development board. It allows wireless programming via BLE, supports Bluetooth HID, AT command to config BLE and you can upgrade BLE firmware easily. Bluno is also compatible with all Arduino Uno pins which means any project made with Uno can directly go wireless! 

What’s more, there are Apps for Bluno (both Android and IOS) and they are completely opensource. You can modify and develop your own BLE-hardware platform. Click on the Wikidocs link for a quick demo video covering some of the major features of Bluno with the help of an Accessory Shield for Bluno. 

In short, you can use Bluno with any Bluetooth 4.0 compatible devices and enjoy features such as wireless transmission, master and slave settings, wireless programming and even establishing a Bluetooth HID connection with the PC between devices.
