Important Notes
CLI aux mode migration
inav 2.5 moves the CLI aux mode value from a boxid that was not guaranteed to be stable between releases to a permmanentId that is guaranteed to be stable between releases. This is a "breaking" change for inav 2.5 that brings stability in the future.
In order to use a diff or dump from 2.4 or earlier in inav 2.5, the user must do one of the following:
- Remove
auxsettings from thediff/dumpand recreate them in inav 2.5; or - Use the box2perm tool to migrate the
diff/dumpautomatically; or - Manually edit the
auxsettings; a conversion table is provided as part of the box2perm documentation.
F3 Deprecation
STM32 F3 flight controllers like Omnibus F3 or SP Racing F3 are deprecated and soon they will reach the end of support in INAV. If you are still using F3 boards, please migrate to F4 or F7.
Upgrading from 2.4
- Download and install the new configurator
- Save to a file the current diff all from the CLI.
- Modify the
diffto update or remove theauxstatements - Upgrade to INAV 2.5 using the Full Erase option in the configurator.
- Upload your OSD font of choice from the OSD tab.
- Go the CLI again and paste the contents on the file you previously create and write save , press ENTER and done!
- You should be ready, explore new 2.5 features and enjoy!
Upgrading from 2.3 or older version
Please follow the instructions on this page.
New targets:
- AIRBOTF7
- OMMINBUSF7NANOV2

New drivers and protocols

Initial Rover and Boat support (@DzikuVx)
Starting from version 2.5, INAV supports Rovers and Boats (more general: ground and water vehicles without altitude control with yaw steering only. Remark: tanks and vehicles with differential steering are also supported).
The Rover and Boat related features:
- Flight modes: PosHold, AltHold, Cruise, Launch, Loiter Direction Change, Angle, Horizon, FPV Angle Mix, Turn Assist, Airmode are not available on Rover and Boat platforms
- Feature 3D is renamed to Reversible Motors
- Reversible ESCs are now working correctly
- New Heading PID controller used for YAW control on rovers and boats
- Return To Home is working. Rover will disarm at the end of RTH procedure. Bear in mind, it will return in a straight line, no Smart RTH support yet.
- Waypoint Missions are operational. Rover will drive directly int the direction of the Waypoint. At the last Waypoint, it will stop motors instead of loitering.
Reversible ESCs support (@DzikuVx)
Description
New Matrix Filters for Multirotors (@DzikuVx)
The new Matrix Notch filter comes enabled by default on INAV. It's a dynamic notch filter that detects noise frequencies on each individual axis (X, Y and Z) and apply the filters to each axis, resulting in a much better noise handling.
Check out this video to see a detailed explanation of how the Matrix Filter works.
JUMP, HOLD and LAND Waypoint types (@giacomo892, @Jacky2k, @stronnag)
INAV 2.5 supports additional waypoint types, allowing more complex missions to be performed.
- JUMP: Defines a 'jump' to another waypoint, allowing mission loops (backward jump) and forward jumps. The number of jump iterations is also user defined.
- POSHOLD_TIME: Defines the amount of time for which the aircraft will loiter at the waypoint position before proceeding to the next waypoint.
- LAND: Defines a location for landing. This allows INAV to perform one-way missions.
The navigation messages wiki page provides more information and annotated examples.
HUD POI Waypoints markers (@OlivierC-FR)
Shows the next waypoints in the hud. To enable this feature, enter the count of next waypoints in the CLI command:
set osd_hud_wp_disp = 0 to 3
Or on the CMS menu: OSD > HUD > Displayed items > Next waypoints: (from 0 to 3, 0 means disabled)
Then start a WP mission, the next WPs will appear as soon as the mission is loaded in FC memory AND that the aircraft has a valid GPS heading, so it must move if it's not fitted with a magnetometer.
Servo S.BUS output (@digitalentity)
It's now possible to connect S.BUS servos to INAV. You can configure INAV to output servo commands as S.BUS stream on one of the serial ports. Important note - F4 boards generally don't support inversion on serial ports, for those boards a hardware inverter might be required.
VTX/CMS Unification (@digitalentity)
Now CMS has one unified page for configuring VTX settings. No need to remember which protocol your VTX is talking (Tramp, S.Audio or other).
ESC Sensor listen-only mode (@digitalentity)
ESC sensor can now be put to listen-only mode, allowing ESC sensor functionality to be used when an ESC is connected with a PWM-based protocol and configured to sent telemetry automatically. This will be useful on airplanes to provide RPM feedback without the need to use DSHOT.
Legacy Targets
Due to flash / memory restrictions the following functions have been disabled on F3 targets:
- Pitot
- Multirotor braking
