content: Bluetooth heart rate monitor with a simple protocol? I've been looking for cheap Chinese Bluetooth heart rate monitors, I want to read the raw data and translate it to CSV, or alternatively have an app that allows me to export the data in some common format such as xml. So far I only found models with a lot of extra functionalities such as SMSnotifications and generally some kind of integration with Android phones which should make for a complicated protocol (over Bluetooth) which in turn would be time consuming to reverse engineer. Any suggestions on how to accomplish this?
