Database Interpretation #167

Open notandorr opened 5 years ago

notandorr commented 5 years ago

Not an issue exactly but a doubt. How do you interpret the .db file? eg: if I get data for Sensors as below

timestamp: 1560244856709 deviceid: b locationid: b bluetooth : wifi:"a":-91,"b":-92,"c":-64,"d":-83,"e":-86,"f":-88,"g":-85,"h":-86,"i":-88,"j":-78,"k":-81,"l":-84,"m":-84

how would you read the wifi column? In other words what do the abc's represent? I thought wifi column showed BSSID but it doesn't look like one.

Also in the keystore table what do NB1 , NB2 , ProbabilityMeans show?

Those are encoded. The NB1/NB2 refer to Naive-Bayes: https://www.internalpositioning.com/doc/faq.md
