I know some medical research scientists who are using activity levels recorded on Jawbone devices to correlate against recovery times from surgical procedures. The only hangup is that Jawbone as a company has shut down, and our devices can no longer sync. Rumour has it that you can get step counts off the devices via BLE, without the need for a remote server. This probably involves reverse-engineering the manufacturer's android app. Has anyone out there done this before? Can you help me extract some data from now-unsupported devices?
