Note

Please let me know if you have tested this app on another drone so I can update this README.

How do I know if it worked?

Open the DJI Fly app and go to the Transmission tab. Look at the horizontal bar around -90 dBm:

• If it lines up with the 1km mark, your drone is in CE mode.
• If it falls below the 1km mark, your drone is in FCC mode.

Check the images below for reference.
