+# HeartRateGame #
+
+Demonstrates how to check a Bluetooth-connection, discover LE-devices, connect
+to devices, discover services and finally connect to a heartrate-service.
+The purpose of the game is increase the heartrate so much as possible in 60s.
+Relax before starting the game. Don't be too nervous, it increases the heartrate!
