wayland/vl53l1x-time-of-flight/set-distance-mode
Set distance mode. The VL53L1X has three distance modes (DM): short, medium, and long.
Long distance mode allows the longest possible ranging distance of 4 m to be reached. However, this maximum ranging distance is impacted by ambient light.
Short distance mode is more immune to ambient light, but its maximum ranging distance is typically limited to 1.3 m.
