Dear micmisur,
To uploading time interval you need to use next command with the necessary parameters:
fix030s030m**n+password
Tracker will report a real-time location every 30 seconds when ACC is ON, and report every 30 minutes when ACC is OFF.
Note: The interval must not less than 10s.
Did you try this command to change time interval?
