Thanks Jay! Being in my mid-40's, assuming it's a straight-line graph, I'm spot on with approx 1 hour of deep sleep then! Probably even getting more REM than average, as typically nearer to 2 hours, and less overall wake time, though often split across several different events. Very interesting!
I can't see it explicitly mentioned in prior posts, but that maybe because I don't fully understand some of the previous documents, but perhaps someone can point me in the right direction if that is the case.....
Do we know what is the data that is transmitted over bluetooth, format, content, any encryption? Is there pre-processing in the sensor you wear on the headband, or is all the processing and inference about sleep state in either the bedside device or iphone/iPad/Android app? Does that vary between mobile and bedside versions?
If I'm going to use the data logging approach, and only have the mobile version, it would be simplest if I could do that in real-time and connect my headband directly to the raspberry Pi, over bluetooth, however, if the proprietary algorithms that convert braiwave data to inferred sleep state are only in the app, I will have to manually extract the data from the app and process it offline later. If I'm just looking at things like temperature, that vary relatively slowly, time synching betwen datasets isn't likely to be critical, but, you know, if I can do it all at the same time, it would be less hassle and therefore better
