These are the few GSPro settings that change what PuttBay can do.
See when PuttBay is ready
In GSPro, open Settings > Visual and turn on Show Ball Ready Indicator. The white arrows next to the ball turn green when PuttBay is ready for a shot.
If GSPro stopped answering
If the GSPro tile says it stopped answering, open Settings > System in GSPro and choose Reset GSPro Connect. The full tile message is GSPro's connect app went silent. Reset GSPro Connect in GSPro's settings, or Close GSPro too. If reset does not work, choose Close GSPro too in PuttBay, then start again.
Let the camera do the putting
When camera putting is on, turn off GSPro Auto Putt so your real putt counts. Gimmes are fine.
GSPro must also have the putter selected before PuttBay sends a camera putt. See Why a putt did not reach GSPro if a roll was measured but held.
Playing online with a partner
Your partner's shots can move your team's ball in GSPro. PuttBay only sends the shots and putts played on your mat.
