Bluno - BLE with Arduino Uno

Introduction: It's time to get Bluetooth 4.0 into your project, together with your phone! For aficionados of smart devices and wearables, now you can go further than hacking things bought in the market to building your own prototype out of garage. Bluno board 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 smart. 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 with a TI CC2540 BT 4.0 chip with the Arduino UNO development board. It allows wireless programming via BLE, supports Bluetooth HID, supports AT command to config the 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!

Whatsmore, we also developed the App for the Bluno (both Android and IOS), and they are completely opensource, so that you can modify and develope your own BLE-hardware platform. Below is a quick demo video covering some of the major features of Bluno with the help of an Accessory Shield for Bluno, which will also be available very soon.

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 burning, and even establishing a Bluetooth HID connection with the PC between devices.

Note: For the demo application and arduino code, we integrated dfrobot wireless libraries for the beginners. The idea is supplying a simple way for you to use wireless modules without learning the wireless comunication protocol.However, for the developer, recommend to custom or choose the protocol according to the product features or the application.
