• LOW BATTERY USAGE - when we do not use gps nor nerworks, the power consumption will be very low

HOW TO USE

First of all, you should be able to build an Android project and install this on your Android device. Or, you can download Debug version .apk.

• Logging Toggle to enable logging or disable logging.
• Scan Now Button to do 1 time wifi scanning and write to log file.
• passive Toggle to enable or disable a interval timer to active scan wifi. Enable this if you wanna higher frequency of wifi scan than OS default. You can not change this when logging is enabled.
• 1 minutes Toggle to choose active scan fequency by every 1 minutes or every 30 seconds. You can not change this when logging is enabled.
• LogFile change the logfile name, default will be your sdcard_directory/ssidLogger.log . You can not change this when logging is enabled.
• Size display current logfile size
• FreeSpace display current sdcard free space
• Comment write one line of comment into log file

Generate GPX

We provides a perl script to generate gpx from the log file:

cat ssidLogger.log | ./log2gpx.pl > ourput.gpx

log2gpx.pl will store lat/lon cache at the file /tmp/bssidCache to speed up the API look up time on duplicate bssid. If you want to clear up the cache, just delete this file.
