android bluetooth serial communication

Always wanted to write a technical document, but due to the limited self-inductance ability is not able to pen, recently made a on the Android platform to achieve and C language communication to operate the Bluetooth module project, the middle encountered a lot of problems, but also on the internet a lot of information, in the completion of the main functions, th

I recently in the study of embedded serial communication, the task is to write a mobile phone-side remote control to control the double-wheel balance trolley. The interface only takes one hours to write, and the important question is how to communicate with the SPP-CA Bluetooth module that the board is carrying.The Spp-ca module comes with code, and all I use her
