What's New

Keepalive Re-Apply Loop

  • New toggle: keeps re-applying FCC every 2 seconds in the background
  • Prevents DJI Fly from resetting radio back to CE mode
  • Same technique used by NLD FCC — continuously flips FCC back if DJI Fly resets it

Launch DJI Fly Button

  • After enabling FCC, tap 'Launch DJI Fly' to open DJI Fly directly
  • Keep FreeFCC running in background with keepalive enabled
  • FCC mode stays active while you fly

NLD SET Parameter Command

  • Added cmdset=4 cmdid=0x33 (SET parameter) with 0xFFFF altitude unlock
  • This is the DUMPL command that NLD FCC uses for altitude unlock

Proper Release Signing

  • APK is now signed with a proper release keystore (not debug)
  • You may need to uninstall the old v1.4.01 before installing v1.4.02

Note on Altitude Unlock

Altitude unlock via DUMPL commands may not work on all CE drones — the 120m C0 limit is enforced by the DJI Fly app. The keepalive loop + SET parameter command improves the chances, but if DJI Fly still caps at 120m, the only known fix is a modded DJI Fly APK or firmware patch.
