Introduction

If you have Arduino UNO, MEGA Controller, or Expansion board with xbee socket, you just add DFRobot latest BLE - Blink module, you can use to the function of bluetooth 4.0. Imagine using Arduino or IOS combined with Arduino develop a wearable mobile device, such as smart phones, smart pedometer bracelet and so on. These wearable devices can communicate with your mobile phone via bluetooth 4.0. By linking into star network of low power consumption, low - power bluetooth 4.0 achieves rapid real - time communication. BLE - the LINK is the communication module based on bluetooth 4.0, it uses the XBEE package which is compact and compatible with the XBEE base. It also can run on 3.3V MCU. With our Android and IOS app, you can quickly build the communication between phone and arduinos. Two BLE4.0 modules can realize the point - to - point wireless transparent transmission, master - slave machine setting, wireless program burning, HID connection with PC. At the same time, we provide developers more freedom and support. User not only can debug BLUNO through the AT command, but also update BLE chip program via USB. BLE - LINK bluetooth 4.0 module can be plug on any Arduino MCU with XBEE base, so as to realize the bluetooth wireless control.
