What's new

1. Direct-to-drone USB mode (VCOM)

If FCC doesn't work through the RC, try connecting a second phone directly to the drone's USB-C port. The app auto-detects which mode to use.

AOA mode (phone → RC USB): The normal path. Works if FCC persists after switching to DJI Fly.

VCOM mode (phone → drone USB-C): For drones where DJI Fly resets FCC. Requires a second device:

  • Device 1: DJI Fly connected to RC normally
  • Device 2: FreeFCC USB plugged into the drone's USB-C port

2. Response diagnostics

The activity log now shows every response frame from the controller/drone — parsed with sender, destination, command set/ID, and payload. This shows whether your drone is ACKing the FCC commands or ignoring them.

If you tested before and FCC didn't work: please try v2.0 and share a screenshot of the activity log after tapping Enable FCC. The response frames will tell us exactly what's happening.

How to use

Method 1 — Through RC (AOA):

  1. Close DJI Fly → plug phone into RC TOP USB → Connect → Enable FCC → switch to DJI Fly

Method 2 — Direct to drone (VCOM):

  1. Phone A: run DJI Fly, connected to RC normally
  2. Phone B: run FreeFCC USB, plugged into drone's USB-C port
  3. Tap Connect → Enable FCC on Phone B
  4. FCC persists because DJI Fly never sees the change
