Have anybody seen the working example of one? I've got one but can prove it is not designed to be working. Have 2 guesses: it never made one despite promise or I got the wrong file. Any comment welcome. At the moment I suffer of the forwarding this promise to a customer and not getting it work. No further communication was from the device owner. Want to hear even some idea how to approach commonly known way of counting steps based on the crossing the averaged data. Can discuss my approaches.
