+// Basic Bluetooth sketch HC-06_01
+// Connect the Hc-06 module and communicate using the serial monitor
+//
+// The HC-06 defaults to AT mode when first powered on.
+// The default baud rate is 9600
+// The Hc-06 requires all AT commands to be in uppercase. NL+CR should not be added to the command string
+// Use no line ending in serial monitor
+/*Command  Reply Comment
+  The HC-06 zs-040 expects commands to be in upper case and does not require carriage return and new line (\r\n) characters.
+  Open the serial monitor and select a baud rate of 9600 and ensure “No line ending” is selected from the drop down list at the bottom of the window.
+  Enter “AT” (no quotes) into the top text box and hit Send. If the HC-06 likes you it will say OK. AT is a basic communications test command that allows you to check the HC-06 is connected and communicating.
