- Easy AT command set to get up and running quickly: query die temperature, check the battery voltage, check the connection RSSI or MAC address, and tons more.
- Easy to add Bluetooth Low Energy connectivity to anything with a hardware or software serial port
- The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)
- Built in over-the-air bootloading capability so we can keep you updated with the hottest new firmware.
Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE UART Friend! It connects to your Arduino or other microcontroller or even just a standard FTDI cable for debugging and testing and has nice hardware flow control so you won't have to think about losing data..
This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service. You have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see with an AT Command Set.
