How to Work with Processes > Working with the GPS/Navigation Processes Group

Process Purpose

The "Get GPS Value" process is used to get information from the device’s GPS.

When dealing with GPS related processes, use the "Start/Stop GPS" process to enable/disable the connection to device's GPS feature.

In terms of project execution, add the "Start/Stop GPS" process first and, then, the "Get GPS Value(s)" process. Depending on your project requirements, use the "Start/Stop GPS" process to disable the connection to the device's GPS as soon as it becomes unnecessary.

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the "Get GPS Value(s)" process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.
