   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.
