·The Adafruit Bluefruit LE Breakout allows you to establish an
easy to use wireless link between your Arduino and any compatible iOS or
Android (4.3+) device.
·It works by simulating a UART device beneath the surface,
sending ASCII data back and forth between the devices, letting you decide what
data to send and what to do with it on either end of the connection.This BLE
module can act like an 'every day' UART data link (with an RX and TX
·Send and receive data up to 10 meters away, from your Arduino to
an iOS device.
·Unlike classic Bluetooth, BLE has no big contracts to sign and
no major hoops that you have to jump through to create iOS peripherals that you
can legally design and distribute in the App Store, which makes it a great
choice compared to classic Bluetooth which had (and still has) a lot of
restrictions around it on the iOS platform.
·And now that Android also officially supports Bluetooth Low
Energy (as of Android 4.3), it's also -- finally! -- a universal communication
channel covering the main mobile operating systems people are using
·Adafruit have even made it easy to get started with their very
own BLE connect app that
has a "serial console" for sending/receiving data and also an
'arduino pin i/o control station" to let you set pins on your Arduino
to inputs or outputs, high or low logic or even PWM output, as well as read
button presses and analog inputs. You can start prototyping your accessory and
then use their open source Objective C code to base your
new app on!
·The nRF8001 is nice in that it is just a BLE 'peripheral'
(client) front-end, so you can use any micrcontroller with SPI to drive it.
Adafruit have example C++ code for Arduino, which you can port to any other
microcontroller, but some microcontroller is required - it is not a stand-alone
·Please note: There is not an Android version of the Adafruit
Bluefruit LE App available (our native BLE application) at this
time,however you can use Nordic's Android nRF UART application with the nRF8001
Breakout on BLE capable Android devices (Nexus 4, Nexus 5, Nexus 7, etc.) for
·This is a product for ADVANCED USERS - At this time we recommend
this product for people who are either OK with using the apps available
(Nordic's UART demo or our Bluefruit LE Connect) or are comfortable with
writing iOS apps (and can refer to our App repository). We do not have a
tutorial for writing your own iOS or Android BLE app at this time, don't worry
we're working on one :)
·Adafruit have written an awesome guide to help you
setup your nRF8001 Bluetooth Low Energy breakout, and start using some of the
sample sketches we provide with it to connect to an iOS or Android device.
