-An [Arduino](http://arduino.cc) library for creating custom BLE peripherals with [Nordic Semiconductor](http://www.nordicsemi.com)'s [nRF8001](http://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF8001) or [nR51822](http://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF51822).

-Enables you to create more customized BLE Peripheral's compared to the basic UART most other Arduino BLE libraries provide.
-
-[nRFgo Studio](http://www.nordicsemi.com/chi/node_176/2.4GHz-RF/nRFgo-Studio) (and Windows) is not required when using the [nRF8001](http://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF8001).
+This is heavily based on @sandeepmistry's [arduino-BLEPeripheral](https://github.com/sandeepmistry/arduino-BLEPeripheral) library. This fork adds support for the observer role (i.e. receiving Bluetooth advertisements), but consequently can't support the nRF8001 anymore.
