Hi there! I see your BTS OFFICIAL LIGHT STICK MOTS SE is having trouble staying synced with your iPhone 14. I’m here to help you get that sorted out.

To start, can you tell me a bit more about what happens when you try to sync? For example, does your iPhone show the lightstick in Bluetooth settings and then lose connection? Or does the BTS Official Light Stick app not recognize it at all? Also, have you tried syncing before, and did it work at some point or is this the first time?

Meanwhile, here’s a step-by-step rundown of common fixes that might help with your issue:

1. Bluetooth & Battery Check:
- Make sure Bluetooth is enabled on your iPhone (Settings > Bluetooth).
- Confirm your MOTS SE light stick is fully charged or has fresh batteries. Sometimes low power can cause intermittent connections.

2. App Updates & Permissions:
- Ensure the BTS Official Light Stick app is up to date via the App Store.
- Double-check the app has Bluetooth permissions enabled in your iPhone’s privacy settings (Settings > Privacy > Bluetooth).

3. Sync Process:
- Open the BTS Official Light Stick app.
- Turn on your light stick by pressing its button twice (this usually starts Bluetooth pairing mode).
- In the app, go to [More] > [Sync Light Stick] to initiate connection.
- Follow prompts carefully; if the app asks to select between versions, make sure to pick the MOTS SE version if available.

4. Forget Device & Reconnect:
- On your iPhone, in Bluetooth settings, if the light stick appears, tap the ⓘ icon and choose “Forget This Device.”
- Then try to sync again from scratch using the app as above.

5. Close Other Bluetooth Devices:
- Sometimes multiple Bluetooth connections can interfere. Try turning off other devices connected via Bluetooth temporarily while syncing.

If you’ve tried these or if the light stick still won’t stay connected, it could be related to compatibility nuances or app bugs specific to iPhone 14 models. Some users have reported needing to update both the app and light stick firmware to fully fix this.

Let me know which of these steps you’ve tried, and if needed, I can guide you through firmware update checks or suggest next steps! How does that sound?
