VR – Version Information
This command obtains software versions for the measurement platform (MPM) firmware, FirstGPS API, FirstGPS
Library, native RTOS, and native processor (CPU). This is a query-only command.
Note: A complete VR command returns only the version of a particular product component one at a time (either MPM
firmware, API, library, RTOS or CPU). The command must include the component type to obtain the version for any
given query.
