Before Using the APP for Parameter Tuning, please connect the signal wires correctly first
To ensure proper use of the APP tuning function with devices like the Meteor LED strip and EXT PRO frame, follow the connection and setup steps below:
Meteor LED Strip Wiring Instructions
Connect the LED strip to any available UART port on the flight controller, as shown below.

EXT PRO Frame Wiring Instructions
Connect the frame’s LED strip to any available UART port on the flight controller. Refer to the wiring diagram below for details.

Enable MSP on the Corresponding UART
Using a PC ground station or the SpeedyBee Android app with a data cable, enable the MSP function for the UART port used in the previous step.

Once the wiring is complete and the correct UART's MSP function is enabled, you can use the APP to tune the LED strip or frame.
If the issue persists after trying the above steps, contact support through the following methods:

- Use the “Contact Us” page in the APP to send connection logs.
- Provide the following additional details:A video of the connection process (including the LED status on the FC, phone model, and system version);Close-up, focused photos of both sides of the FC.
We’ll assist you in diagnosing the issue further.
We hope the above information helps you resolve the connection problem!
