At the shell prompt, type the following commands:
# cd NMSDemo/2004/BeaconConfigDemo
# ./launchall.sh
Two programs will be launched. The first is called the Beacon Finder, which displays the distance measurement statistics for each beacon. The second application is called Beacon Configuration, which executes the two phases of configuring the adhoc beacon coordinate system and position tracking.
Use the Beacon Finder to verify that the listener is within
range of all beacons. Do this by holding the listener underneath each
beacon and verify that 1) it has a row entry for NUMBEACONS
different beacons and 2) none of the entries have excessively long
last-update times (
5000ms).
Otherwise, some beacons are out of range of the listener and cause the beacon coordiante configuration phase to fail. Please adjust the beacon placement until all the beacons are within range.
Below the numerical statistics are two sub-windows. The first sub-window is a graphical representation of the standard deviation of the measured distances of each beacon within a history window defined by FILTER_WINDOW_MS. The second sub-window is a time ``sweep'' stick plot of the distance measurements (stick height) in the history window. The color of each stick is encoded to correspond to the beacon from which the distance sample is measured.
