Q2: Why is the controller light constantly green?
A: Quick introduction to the controller light state: the green light flashes when connected to the computing unit; a bright green light indicates connected, and the blue light is lit when charging.
Normal operation is the green light flickering for about 1 minute, turning brighter. If it keeps flashing nonstop, look under the computer Windows system if "scrcpy" software has been enabled on the NrealLight-Con option under the setting-Connected devices-Bluetooth option. To re-pair, click the back gear and select FORGET to delete the current controller. Then Re-open the handle switch and reconnect.
When connected, if the marked by the mouse style on screen (as shown below), you have the latest version, otherwise please upgrade. Upgrade happens automatically after connecting to a wireless network.
Premise: the battery of the computing unit or mobile phone has to be more than 30%. When upgrading, make sure that the controller does not leave the computing unit.

If the interface is loose, it will cause intermittent behavior, causing the RGB camera do not function properly. In addition, you can connect to a Windows PC via a USB Type-c interface. Switch the camera to the camera of the Nreal Light to confirm.
