A note for future users of the Bluetooth Low Energy TinyShield (ST). The tutorial demonstrates using
nRF UART v2.0. The Android app does not appear to be current and fails. Fortunately, I did suceed with
nRF Toolbox and its
Universal Asynchronous Receiver/Transmitter (UART) function. To use, select the funtion, press All when the scanner starts, select BlueNRG, et voilà!
General Discoverable Mode.

I also tried
Serial Bluetooth Terminal, but it returns a message
Connection failed: no write characteristic (4/16).
