polarusbdump

USB data dumper for Polar M400 (and other) watches.

I started this project as an attempt to write a polar watch data extractor and converter to TCX format. Right now I just want this to be a simple data dumper, as I figured out how to dump data over Bluetooth and will focus on that project.

Compile

mvn clean package

Run

java -jar target/polarusbdump.jar

Data

All data will be dumped into ${user.home}/.polar/backup/${device.id}/ directory. Please note that this data is still in polar format (Google Procol Buffers encoded).
