+/* Arduino BLE controlled Audio Player for nRF52
+ * 
+ * This is an example of me playing around with BLE control and different
+ * services/characteristics to test the AutoAnalogAudio library.
+ *
+ * Requirements:
+ * 1. nRF52 Device (Tested on nRF52840)
+*  2. SD Card with WAV files: 8-bit, 16-24kHz, Mono
+ * 3. I2S or Analog Amplifier + Speaker connected
+ * 4. Mobile device or 'other' with nRF Connect installed
+ *
+ * Connect via nRF Connect App:
+ * 1. Device should come up as BLE Audio Player
+ * 2. You should see:
+ *   a: Common Audio
+*    b: Audio Input Type:
+      Send a UTF-8 String to play a file: myfileDirectory/myfilename.wav
+ *   c: Audio Input Control Point:
+      Send an Unsigned value between 0-10 to set the volume low-high
