2 days ago First thing is sort of problem device is very small and hard to wear if opened and tinkered, but I will try to do it.
Data doesn't get encrypted between device and app, this is actually big problem, because you are able to use device and read data from anyone near.
On data readings I am able to read heart rate and rr, for all times, I am currently unable to find out how to read temperature and blood oxygen, I think that temperature is constantly measured, but not shown, but blood oxygen is measured when device detects sleep.
Okay so what I have come up with is the following: read out the data of the sensors directly (needs physical manipulation), read out the raw data from the sensors to jump over the part where the sensor data probably gets encrypted. Then get the raw data that got sent to whoop and the results where you need the subscription for. Then let some datascience algorithms figure out the combination of the raw sensor data results, how to combine those together, to achieve the same results regarding the interpretation of the raw sensor data.
