Description
The Bluefruit LE module is an nRF51822 chipset from Nordic programmed with multifunction code that 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.
The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set 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. You can also use the AT commands to query the die temperature check the battery voltage and more check the connection RSSI or MAC address and tons more. Really way too long to list here!
