This is largely a "demo" app showing howtoconnect to the nRF8001 Breakout Board from Adafruit (https://www.adafruit.com/products/1697).Adafruit haspublished a great Androidapp(https://play.google.com/store/apps/details?id=com.adafruit.bluefruit.le.connect&hl=en)forcommunicating with the device, however they didn't post thesource(that I could find). I also needed to be able to logthecommunications and AFAIK none of the existing apps do that.Thisturned out to be a great learning opportunity for myself; I'monlypublishing it here in case it is useful for anybody else.Features:* Connect to nRF8001 UART devices over the Bluetooth LowEnergyprotocol.* Receive UART communications and log them to a file onyourdevice's SD card (in the Documents folder).Full sources for this app are available at https://github.com/FuzzyWuzzie/BTLEDataLogger
