BLE LINK BLUETOOTH 4.0
BLE Link is a communication module based on bluetooth 4.0, it uses the XBEE model which is compact and is compatible with all shields with XBEE socket.
BLE Link supports both 5V and 3.3V MCUs. We've also developed Apps on both Android and IOS platform for you to start commumication between phone and arduinos immediately. With two BLE Links, you can enjoy features like point-to-point wireless transparent transmission, master-slave machine setting, wireless program burning and HID connection with PC. At the same time, we provide developers more freedom and support: users can not only debug Bluno through AT command, but also update BLE chip program via USB.
Bluetooth Low Energy (BLE 4.0) – nRF8001 LE
Bluetooth Module- RN-41
(Ask for A Quotation)
The module from Roving Networks is powerful, small, and very easy to use. This Bluetooth module is designed to replace serial cables. The Bluetooth stack is completely encapsulated. The end user just sees serial characters being transmitted back and forth. Press the 'A' character from a terminal program on your computer and an 'A' will be pushed out the TX pin of the Bluetooth module.
Bluno Nano – An Arduino Nano with Bluetooth 4.0
The Bluno Nano is perfect for BLE projects with limited space or weight. Everything is getting smart now: wristbands and watches monitor your daily behaviour and become social; phone-controlled camera add-ons move and take shots as you like; smart gardens grow virtually in your iPad and sharing is made easy. The Bluetooth Low Energy technology has made it easy and achievable. DFRobot's Bluno family is first of its kind in integrating BT 4.0(BLE) module into Arduino Uno, making it an ideal prototyping platform for developers to go wireless. 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 easy.
