INAV 8 no longer includes F411 targets as part of the official release.

GPS: UBLOX7 and UBLOX have been merged into a single UBLOX option, and units with older firmware are now deprecated. Only M8 and newer will be supported in the future.

Make sure to remove props and check your motor and servo outputs before powering your upgraded flight controller with a battery for the first time. The changes to enable flexible motor and servo allocation may change what outputs your configuration uses by default.

Known Issues in 8.0

  • None

  5. Select Keep current settings from the defaults pop-up
  6. Go to CLI and restore your edited inav diff
  7. Done

This tool can help migrate your INAV 7.x diff over to INAV 8.0.0. It will take care of the major changes that have been highlighted in these release notes.

Upgrading from older versions

Please follow the instructions on this page.

Highlights

Geozones

The Geozone feature allows pilots to define one or multiple areas on the map in Mission Control, to prevent accidental flying outside of allowed zones (Flight-Zones, FZ) or to avoid certain areas they are not allowed or not willing to fly in (No-Flight-Zone, NFZ). This type of feature might be known to many pilots as a "Geofence" and despite providing the same core functionality, INAV Geozones are significantly more versatile and provide more safety and features. Read the Documentation for more info
IMPORTANT: Geozones will not be available for STM32F722 based Flight Controllers due to insufficient flash storage.

GPS Fix estimation (dead reckoning, RTH without GPS fix) for Airplanes

This new feature allows INAV to return to its launch location, in case of a failed GPS due to hardware failure or interference. INAV will use the remaining sensors and the already calculated wind speed and direction, to blindly return towards the home location. For this feature, no extra sensors are strictly necessary, aside from the standard Accelerometer, Gyroscope and Barometer, but its highly recommended to have a compass and for best precision, to also have an Airspeed sensor. The feature will not be able to precisely return to the pilot, but it allows the Aircraft to either get out of an area with interferences, or to give the pilot time and a chance to regain control for a manual return, when the aircraft is closer. Details here

MSP-Linkstats

A new MSP Message that allows RC links that communicate with the Flight controller via MSP, to provide Link Information to INAV like LQ, RSSI, Power Level, SNR and more. The first RC Link to support this is the mLRS Project with more possibly coming in the future. Details here

MSP-VTX

MSP-VTX has been updated by @geoffsim to increase compatibility with HDZero vtxs.

Mavlink Advancement for MavlinkRC

The previously simple Mavlink Telemetry was extended to be compatible with flow control capable links (Thanks @MUSTARDTIGERFPV). This now allows RC Control via Mavlink and Telemetry at the same time over a Single UART. It is tested successfully with ELRS Mavlink-RC and mLRS Mavlink. Additionally it allows the Use of Mission Planner, QGroundControl and potentially other GCS Applications to be used for Flight Monitoring with INAV.
Note: To receive RSSI and LQ for ELRS Mavlink-RC you need to set mavlink_radio_type=ELRS in the CLI. Details here

Walksnail Serial Gimbal and Headtracker support

INAV now also supports the Caddx / Walksnail GM Series Gimbals. These can now be controlled via a dedicated uart UART or via MSP and don't need up to 3 PWM Outputs anymore. This enables the direct Gimbal Control via Head Tracking from Walksnail goggles, without additional wiring. Details Here

OSD Updates

  • Users can change the precision (amount of decimal places) for Altitude and Distance #10431
  • Enhancements for Custom OSD Elements #10282
  • Update arming screen for better space utilisation #10300
  • OSD system message improvements #10090
  • Better organisation of the post flight stats screen with more stats available #9617

ADSB Receiver Support

It is now possible to connect an ADSB receiver to your flight controller and get OSD Warnings if any ADSB enabled Aircraft, is close by. INAV Configurator can show these Aircraft on the map for additional safety of UAV flights. ADSB is supported for generally available receivers like uAvionix pingRX (not tested) and Aerobit TT-SC1 (tested) and should also work with the upcoming PicoADSB Details here

I-Term Lock for Fixed Wing

The Fixed Wing PIDFF Controller was reworked. The PIDs are now attenuated based in the amount of Setpoint (Stick deflection in Acro Mode) for a more "Manual" flight feel during aggressive inputs while keeping the locked in feel of a PID-Assisted flight. This allows the Pilot to have a PID tune with very high P and I values for a locked in flight feel, while keeping a good manual feeling of the plane's flight characteristics, especially when flying slow. Additionally the Attenuation fixes the Bounce-Back caused by the Integral of the PID controller, after sharp roll or pitch inputs. Details Here

U-Blox AssistNow Support in INAV Configurator

AssistNow is a Service that provides GPS Satellite information data for offline-applications, to dramatically increase the time to fix for GPS Devices. By Providing your own AssistNow Token, INAV Configurator can automatically download the latest data set and transfer it to any connected INAV UAV. With this, a GPS fix after cold start should merely take seconds instead of minutes. This is especially helpful for people who go fly with a big fleet of aircraft. Details here

Sensor ID change for SmartPort telemetry

The sensor IDs for the Modes and GNSS data have changed in SmartPort telemetry. The default settings in INAV are to now use the new sensor IDs. The INAV OpenTX-Telemetry-Widget has been updated to use these new IDs. So you will not see any issues when using the latest version of this widget. However, if you use another widget or app that uses the SmartPort telemetry. It is recommended to inform the creator of the app/widget, as the old sensor IDs will be removed in INAV 10.0.0. Details here

You can change INAV to use the old sensor IDs with the CLI parameter set frsky_use_legacy_gps_mode_sensor_ids = on. However, it is recommended to only use this only as long as necessary. This parameter will also be removed in INAV10.0.0.

Improved SD Card support for F7 and H7 flight controllers using SDIO

This version of INAV fixes some long standing bugs with the SDIO driver for H7 and F765 flight controllers. Now they share the same HAL based driver and fixes.
This affects a small number of targets, as most targets use the older and slower SPI based access to SD cards.
Moving forward, SDIO is the preferred and recommend way to implement SD Card blackbox in INAV, as it is faster than SPI and support up to 4BIT wide data access, versus SPI 1 bit.

This change affects the following targets:

  • FLYWOOH743PRO
  • IFLIGHT_BLITZ_H7_PRO
  • KAKUTEH7WING
  • MATEKF765
  • MATEKH743
  • MICOAIR743
  • NEUTRONRCH7BT
  • PIXRACER
  • TBS_LUCID_H7

DJI O4 support

DJI released a new air unit, and while rumors suggested it would include full INAV font support, that is unfortunately not true with the released firmware. There is also a bug on DJI firmware that prevents it from detecting when the flight controller is armed and leaves the air unit stuck in low power mode.

There are two possible workaround for the arming issues:

  1. Turn off low power mode This should work with older INAV versions as well
  2. On INAV 8.0.0, you can type this on the cli: set enable_broken_o4_workaround = ON

With the added workarounds, setup in INAV should be the same as O3.

Other important changes:

  • Multirotor inverted crash detection #10099
  • Waypoint tracking improvements #10278 (Note usage change for nav_fw_wp_tracking_accuracy may require change of setting)
  • Fixed wing altitude velocity control #9471 (see know issues above related to this change)

Diff breaking changes

Profile consolidation

The profile CLI command has been renamed to control_profile. When updating from an older version of INAV. You will need to edit your diff with this change. For example: 

# profile
profile 1

set fw_p_pitch = 14
set fw_i_pitch = 5
set fw_d_pitch = 5
set fw_ff_pitch = 137
...

Will become 

# profile
control_profile 1

set fw_p_pitch = 14
set fw_i_pitch = 5
set fw_d_pitch = 5
set fw_ff_pitch = 137
...

OSD Custom Elements

If you have previously used OSD Custom Elements. You will need to update the diff for these, so that they continue to work in the same way. The system has been expanded to allow the use of logic condition results and have more numerical variations. To keep your OSD Custom Elements working, you will need to change the element type IDs, if they are 4, 5, 6, or 7. The table below shows the old and new IDs.

Numeric format Old name Old ID New name New ID
000 CUSTOM_ELEMENT_TYPE_GV_SMALL 6 CUSTOM_ELEMENT_TYPE_GV_3 7
00000 CUSTOM_ELEMENT_TYPE_GV 4 CUSTOM_ELEMENT_TYPE_GV_5 9
0.0 CUSTOM_ELEMENT_TYPE_GV_SMALL_FLOAT 7 CUSTOM_ELEMENT_TYPE_GV_FLOAT_1_1 10
0000.0 CUSTOM_ELEMENT_TYPE_GV_FLOAT 5 CUSTOM_ELEMENT_TYPE_GV_FLOAT_4_1 16

Below, you can see the position of the IDs that you need to change if they are 4, 5, 6, or 7.
