This is an old revision of the document!
There is initially two goals to this starting investigation : one is to extract data from the system just because I can, and the other, much more concrete is that, after my bike fall the very first day I had it, the button to turn the 4 blink light stop working. It’s not a button that you need a lot but when you need it, you really do, and so I thought if I could reproduce what this button do programmatically, I would not have to replace a 300€ commodo and rely on my phone instead…. Let’s see if that is even possible.
