Diagnostic Log File
The LTM application has the option to write the battery status to a diagnostic log file.
The file format is UTF-8 (simple ASCII). The file can be read on a PC using any text editor.
The log file is located in the “Internal Storage\Android\data\com.lava.tabletmanager7\files\”
folder. The log file name is LTM_***_LOG.txt. The *** portion of the file is the device serial
number.
The “log-file-rate” defines the number of minutes between updates of the diagnostic log file. The
permitted range is 0 to 1440, with a default of 0. A value of 0 results in updates only for changes
in charge direction.
The “log-file-limit” defines the maximum size of the diagnostic log file in units of 1000000
characters. The permitted range is 0 to 100, with a default of 0. A 0 disables the log file.
The log file can be erased at any time. The LTM application always appends new information.
When the log file is created, the current configuration settings from the configuration file are
written to a header in the file. Subsequent changes to the configuration file are not written until a
new log file has to be created.
Each line of data contains 16 fields. A comma separates each field of data. The first line after the
header contains a short “title” for each field, which is useful for some graphing applications.
