Troubleshooting
- Primary Test: Make sure your software and computer operating systems (as applicable) are supported by the Vernier GPS (see requirements below).

Go outside with an unobstructed view of the sky, and wait for enough satellites to be acquired. The first time could take up to 5 min (or 30 min with an original VGPS).
