Problem: Cannot connect to the controller via Bluetooth.

Possible Causes:

• Bluetooth is disabled on your phone.
• Controller is not powered on.
• Interference from other Bluetooth devices.
• App is not functioning correctly.

Solutions:

• Ensure Bluetooth is enabled on your smartphone.
• Verify the controller is powered on and receiving sufficient power.
• Try restarting the app and your phone's Bluetooth.
• Move closer to the controller to ensure a strong Bluetooth signal.
• Temporarily disable other Bluetooth devices nearby.

Problem: LED strip is not lighting up.

Possible Causes:

• No power to the controller.
• Incorrect connection of the LED strip.
• Incompatible LED strip.
• Faulty LED strip or controller.

Solutions:

• Check the USB power connection and ensure the controller's indicator light (if present) is on.
