Following some early unsuccessful attempts at using an JY-MCY HC06 slave bluetooth module I have spent many hours on the internet in an effort to understand the module' capabilities and how to use it. As a novice you soon discover how tricky these devices can be. The attached document gives you some of my insights and working examples of using slave and master JY-MCU HC06 bluetooth modules in an effort to help others get started. The document was written in LibreOffice freeware but should be readable in MicrosoftOffice. Good luck.
