Python library to work with Lenovo HW01

Project description

Lenovo HW01 Build Status

Library to work with Lenovo HW01. To be used in place of Android Lenovo Healthy app.


Traffic analysis

In order to analyse communication between official Android app Lenovo Healthy and Lenovo HW01 device, additional app NordicSemiconductor/Android-nRF-Connect is used to perform traffic logging.

It allows us to write an API library to interact with the watch without using the official Android app.
