possible when space available on the storage media is exhausted. Together
with scheduled file closing, this option can be used to configure the
SDR2-USB as a circular buffer— as the disk fills, the oldest file is
overwritten.
// file name and path to record to
Filename=DATA\GPS0000.txt
// create new files when recording starts
Append=0
// buffer data when stopped
FlushBuffer=0
// always record if media is present
ForceRecording=1
// overwrite oldest file if necessary
OverWriteOldest=1
4.1.4 Scheduled File Closing Commands
Scheduled file closing, together with Append=0, allows the user to divide
recorded data into files of a more manageable size.
FileClose (default=0): The FileClose setup file line enables and disables
scheduled file closing.
FileCloseSeconds: The FileCloseSeconds setting configures the SDR2-USB
to close the current file and restart recording after the specified number of
seconds. For example, to configure the recorder to restart recording every
hour, use FileCloseSeconds=3600 (3600 seconds=60 minutes=1 hour).
FileCloseBytes: The FileCloseBytes setup file line configures the recorder to
close the current file and restart recording once the current file reaches the
specified number of bytes. For example, use FileCloseBytes=1048576 to
configure the SDR2-USB to create a new file if the size reaches 1 megabyte.
StartTime, StopTime: The StartTime and StopTime lines configure the
recorder to start and stop at specific times of day (specified in 24-hour
HH:MM:SS format). If start and stop times are equal, each file will contain
24 hours of data. FlushBuffer=1 (see above) is usually used if start and stop
times are different in order to reject data received while recording was
stopped.
// enable scheduled file closing
FileClose=1
// record only during business hours
StartTime=08:00:00
StopTime=17:00:00
FlushBuffer=1
4.1.5 Time Stamping Commands
The SDR2-USB can insert time and date information into files during
recording. Among other things, this is useful for scientific data analysis and
historical trending studies.
Timestamp (default=0): The Timestamp setup file line enables date/time
stamping.
