Quick Start

1.offline 1) fingerprints calibration. a) ./tool/bt-dev-con && xgps & b) ./run -n -r c) ./offline.py -c dat/.rmp d) ./offline.py -u 1 2) Dumbtest for stability. ./run -d 3) Compile all .py to .pyc. ./run -m

2.online 1) Pure fingerprinting. sudo ./online.py -v 2) Accuracy evaluation(GPS available). sudo ./test.py -v
