Looks nice, and quite cheap (less than 30 bucks), but we don't have such a device and no specs, no nothing. Do you have one and want to help add support for it?

Unlike many activity monitors, 37 Body says the 37 Light wristband not only counts the wearer's time at rest, number of steps, and other physical activity, but also simultaneously accurately tracks and records a range of physiological data including blood pressure, resting heart rate, respiratory frequency, degree of fatigue, and even the wearer’s ‘mood’, using the principle of heart rate variability (HRV).

@cpfeiffer Yes, I've bought one at gearbest for $16, it should arrive soon, but there were claims that it doesn't measure blood pressure at all and just show you some random values based on the weight in profile ;-) Also there were claims disproving that claims - so I want to reverse-engineer their BLE protocol to find out what it really measures and what is just calculated by it's app.

Let us know what you find out, and if you need help integrating support for it. I'm curious about the outcome, in any case :-)
