Is it possible to change the program of the robots in the Bluetooth monopod?

Question

Bluetooth

I had a Selfie stick (Monopod) on a bluetooth connection, performing the click=shot function
By pressing the button on the stick, I get an increase in volume, which on an iPhone means to take a picture (If the Camera application is running), and it turned out that the tripod itself was broken, and I removed the module from the bottom of the stick,
As I see it:
1) connected it to the computer via USB and found some kind of program
2) uploaded the finished code, or wrote my own type (if click_ to something happens)
But how to do it all,
PS The module has 2 output wiring (Red Black) + and - which is very good.
Or still solder the button, and walk like a Hacker =)???

Answer 1

In the stick is some kind of processor manufactured at the factory. Most likely, to connect it to USB, you need a programmer, or some kind of strapping scheme (if it is possible to connect it). Then you just have to dump the program from this microprocessor, disassemble it, add something like: (if click_ to something happens) in the assembler of this microprocessor. Then everything needs to be debugged, and voila: you have a new device!
In terms of time, it may take you a month with knowledge of the main families of processors, and during this time a self-stick from friendly China may just come.
