BTS Official Light Stick Ver.4

The BTS Official Light Stick Ver.4 App is the companion for the Light Stick Ver.4, enabling Bluetooth pairing, Concert Mode with stage-synced light patterns, and firmware updates. To connect, turn off the Light Stick, hold the handle buttons for 2 seconds to enter Bluetooth Mode (blue blinking), then enable Bluetooth on your phone and pair. In Concert Mode you can check upcoming events and whether pairing is required and enjoy light effects tied to the performance. The app also supports updating the Light Stick firmware to the latest version.

App permissions and concert tips: Bluetooth is required to connect and control the Light Stick. Location is used as a reference for app services (data not stored). Photo allows saving/loading a code image, and Storage stores necessary app data. If pairing is needed at a venue, register the concert information in Concert Mode before pairing. Be mindful of on-site conditions, update firmware beforehand, and replace batteries as needed; the Light Stick will stay paired during the show with continuous light effects.
