bluetooth hc05 is traditional or ble, ask before write data code is must write is similar to that of the interface on the debugging assistants, such as the display list, links and send button

That see you need, if you only require to send data don't write interface can also, if you want to display data that is about to write the process of the interface

I see other posts of bluetooth module adapted these are all very full, I only need to send two coordinates data, on the basis of I've already finished my test, write to send data part, I need to do is to write a connection function and the function of sending, adapter if these can be skipped
