How to reprogram a fitness bracelet?

Question

Do it yourself

I bought myself a new bracelet, but the old one (Mi Band 2) has nowhere to go. I want to try something with it. For example, program a small game into it, make a stopwatch or something else.

Tell me, with the help of which programming languages ​​can you rewrite the bracelet software and how to write it there later (what programs or equipment are needed)?

Answer 1

I tried to somehow have fun with Mi Band 2 in Python. From a phone connected to it via Bluetooth. Already made him vibrate for a while. :)
And I got through to him using a library that works with bluetooth. Perhaps you should also dig in the direction of Python + Bluetooth libraries .

Answer 2

It is not known how the original mi band firmware works, so writing your own will not work - there will be a brick.

Answer 3

No way, this model, like many others, is not reprogrammed.
