Important Notes

PCA9685 PWM driver no longer supported

The I2C PCA9685 servo driver is no longer supported as obsolete and not widely adopted. All PCA9685 setups are advised to upgrade to SBUS output and SBUS to PWM decoders

Gyro and Acc alignment settings removed

The align_acc and align_gyro settings are removed. Gyro/Acc orientation should always be set with align_board_yaw

GPS Glitch Detection

The NAV_GPS_GLITCH_DETECTION was removed as not suitable for modern aircraft. There is no user action required

Removal of depreciated MSP frames

INAV 5 removed the support for the following MSP frames:

• MSP_IDENT
• MSP_PID
• MSP_PID_CONTROLLER
• MSP_BF_CONFIG
• MSP_BF_BUILD_INFO
• MSP_SET_PID_CONTROLLER
• MSP_SET_PID
• MSP_SET_BF_CONFIG
• MSP_CF_SERIAL_CONFIG
• MSP_SET_CF_SERIAL_CONFIG

No user action is required in the case of the INAV Configurator or mwptools (mwp etc.). In the case of 3rd party INAV configuration apps, this change might break the compatibility if the app was using any of those frames. SpeedyBee developers have been notified, other apps have to adjust accordingly.

Strict MSP payload length checking

In order to help mitigate the "randomly changed settings" bug, strict MSP payload length checking has been implemented. Fixed size MSP frames that do not specify the correct payload size will be rejected. The INAV Configurator and mwptools (mwp etc.) are compliant. In the case of 3rd party INAV configuration / mission planning / monitoring apps, this change might break interoperability if the app was not correctly setting the payload size. SpeedyBee developers have been notified, other apps may have to adjust accordingly.

Upgrading from a previous release

Upgrading from INAV 4 and 4.1

0. Download and install the new configurator
1. Save to a file the current diff all from the CLI.
2. Upgrade to INAV 5.0 using the Full Erase option in the configurator.
3. Upload your OSD font of choice from the OSD tab.
4. Go to the CLI again and paste the above-described contents from the file you previously created and write save , press ENTER.
5. There are a large number of new, changed, and removed settings. Check carefully that the settings are correct and fix any unrecognized or out-of-range items from the saved configuration.
6. You should be ready, explore new 5.0 features, and enjoy!

Upgrading from older versions

Please follow the instructions on this page.

Important changes

Configurable outputs mode

INAV allows changing the function assignment of ALL PWM outputs. Bear in mind, that it's not resource mapping! This function allows assigning all outputs as motors or all outputs as servos. It's driven by CLI output_mode setting

• AUTO assigns outputs according to the default mapping
• SERVOS assigns all outputs to servos
• MOTORS assigns all outputs to motors

Improved landing detection

Updates landing detection for multirotor and add detection for fixed-wing. Detects when flying and activates landing detection from that point. Multirotor detection was added for non-autonomous landing as well as RTH. Fixed-wing detection is based on velocity, axis rates, and finally absolute movement in roll and pitch (so it probably wouldn't work if stuck in a tree being blown around by the wind). For details see #7270

Add the ability to adjust LED Strip color with RC channel

LED hue can be updated with an RC channel. For example, CLI led 7 8,10::H:6 will adjust hue of LED number 7 based on RC channel 6. For details see #7618

An option to not calibrate the gyro during boot

This feature allows to arm of INAV aircraft on a boat or any other moving vehicle, as it allows to use of stored gyro calibration value instead of calibrating on every boot.

• init_gyro_cal If defined to OFF, it will ignore the gyroscope calibration done at each startup. Instead, the gyroscope's last calibration from when you calibrated will be used. It also means you don't have to keep the UAV stationary during a startup.
• gyro_zero_x gyro X calibration stored
• gyro_zero_y gyro Y calibration stored
• gyro_zero_z gyro Z calibration stored

WP mission waypoint enforce altitude option

Provides an option to force mission waypoint altitude to be achieved before moving on to the next waypoint. If the set altitude hasn't been achieved when the craft arrives at the waypoint it will hold and adjust the altitude as required with a target margin of 100cm. Planes use a spiral loiter whilst changing altitude. The option is set for the whole mission and applicable to basic and timed hold waypoints. For details see #7644

Improved Altitude Hold controller

INAV will now use the SQRT controller for Altitude Control on Multirotors. No extra pilot action required. For details see #7845

TBS Sixty9 SA2.1 UART Configuration

Adds the vtx_smartaudio_stopbits setting that when set to 1 fixes the TBS Sixty9 SmartAudio 2.1 issues.

Rangefinder in Logic Conditions

Adds following value as Logic Conditions Operands:

• AGL_STATUS boolean 1 when AGL can be trusted, 0 when AGL estimate can not be trusted
• AGL integer Above The Groud Altitude in cm
• RANGEFINDER_RAW integer raw distance provided by the rangefinder in cm

Matek 1G3SE control via IRC Tramp

To use the Matek 1G3SE with IRC Tramp. You will need to enter the CLI command set vtx_frequency_group = FREQUENCYGROUP_1G3. You must also make sure that the initial VTx settings in the configuration tab are in a valid range. They are:

• vtx_band 1 or 2
• vtx_channel between 1 and 9
  As part of this change.

The default VTx band has been changed from 4 to 1. If you are updating, please check that the band is still correct for your setup.

For details see #7949

PWM function mapping change for some targets

KAKUTEH7, MAMBAF722_2022A and MAMBAH743 have now 4 motor and 4 servo outputs by default. To enable X8 mode, CLI set output_mode=MOTORS command has to be used.

New targets

Important changes

Filtering changes

With INAV 4.0 there are a couple of important changes in how gyro and D-term are filtered. They mostly affect Multirotor pilots.

1. Kalman filter aka Unicorn Filter is enabled by default
2. Unicorn Filter setup is simplified: you only tune Q factor. Window size and sharpness settings are removed
3. Dynamic Notch aka Matrix Filter is enabled by default
4. Matrix filter has been reworked and simplified. Now you only set minimum frequency and Q factor
5. Matrix filter resolution is now 4 times higher than with INAV 3
6. Static gyro notch was removed
7. First D-term LPF type changed to PT2 and second D-term LPF is disabled - this gives the same filtering as previously but with less settings to worry about
8. The Alpha-Beta-Gamma filter removed
9. The Smith Predictor is enabled by default by the new Configurator defaults

H743 support

INAV 4.0 comes with the full support of all H7 boards compatible with MATEKH743 target. This includes the SD Card and MSC mode support. Bear in mind, CAN and UAVCAN are still not supported by INAV and currently, there are no plans to implement them.

Blackbox improvements

Blackbox now always logs the Control Derivative and Feed Forward components, as well as rate target in degrees-per-seconds.
The latest INAV Blackbox Explorer is required to fully use those features.

New command blackbox allows setting which Blackbox fields are recorded to conserve space and bandwidth. Possible fields are:

• NAV_ACC - Navigation accelerometer readouts
• NAV_PID - Navigation PID debug
• NAV_POS - Current and target position and altitude
• MAG - Magnetometer raw values
• ACC - Accelerometer raw values
• ATTI - Attitude as computed by INAV position estimator
• RC_DATA - RC channels 1-4 as returned by the radio receiver
• RC_COMMAND - RC_DATA converted to [-500:500] scale with expo and headband
• MOTORS - motor output

Usage

• blackbox currently enabled Blackbox fields
• blackbox list all available fields
• blackbox -MOTORS disable MOTORS logging
• blackbox MOTOR enable MOTORS logging

Rate Dynamics

INAV 4.0 adds a port of the EmuFlight Rate Dynamics system. It modifies stick input to change the flight feeling. To find out more refer to:

1. https://www.youtube.com/watch?v=8WyJx2FcLzI
2. https://github.com/emuflight/EmuFlight/wiki/Rate-Dynamics

Below are some presets you might want to try

WP Mission Enhancements

Multi-Mission

Multiple missions may be uploaded to the flight controller and a mission selected for execution by OSD, Stick Command or Mission Planner. Multi-Mission is supported by the inav Configurator and mwp mission planners.

Number of Waypoints

The maximum number of WPs is now 120.

On the fly missions

INAV 4.0 adds the capability to generate an "on the fly" mission while flying using aircraft positions.

Fly By Home Waypoints

INAV 4.0 adds Fly-by-home waypoints. This is a waypoint whose location is set to the home position at arm time.

Fixed-wing changes

Soaring mode

The soaring mode comes to iNav 4.0. The addition is great for people who fly gliders. The soaring mode adds a modifier that you can use to change how Course Hold, Cruise, or Position Hold (loiter) behave. When enabled, it disables altitude control and allows Angle mode to free float in pitch, allowing the plane to soar freely.

Two-stage climb first for RTH

This change allows the climb phase of a climb first RTH to have two separate parts. This is useful for pilots who want to climb first, to clear potential obstacles. But, don't want to be wasting energy flying away from home. This allows you to set a first climb stage altitude. Once it meets or exceeds that altitude, the plane will turn to home and continue climbing to the RTH altitude. See the iNav Wiki for more information.

Autotune no longer tunes P and I

There were often autotunes in iNav 3.0 which resulted in too high P and I. Also, D was not tuned at all. New default PIDs, that will work reasonably on all sizes of planes (#1390) have been added. This should give good results with an autotune, which can then be fine tuned to your plane.

OSD Units

If you previously used the UK units in your OSD. You will now find that your units are set to Metric + MPH. This is the new name for the old UK units. There is also a new UK units set, that better represents transportation units used in the UK. Full details can be found in the pull release.

There is also a new units set aimed at General Aviation pilots. This set uses Knots, Feet, Nautical Miles, 100 Feet per Minute, and Celsius for their respective values.

Important changes

Filtering changes

With INAV 4.0 there are a couple of important changes in how gyro and D-term are filtered. They mostly affect Multirotor pilots.

1. Kalman filter aka Unicorn Filter is enabled by default
2. Unicorn Filter setup is simplified: you only tune Q factor. Window size and sharpness settings are removed
3. Dynamic Notch aka Matrix Filter is enabled by default
4. Matrix filter has been reworked and simplified. Now you only set minimum frequency and Q factor
5. Matrix filter resolution is now 4 times higher than with INAV 3
6. Static gyro notch was removed
7. First D-term LPF type changed to PT2 and second D-term LPF is disabled - this gives the same filtering as previously but with less settings to worry about
8. The Alpha-Beta-Gamma filter removed
9. The Smith Predictor is enabled by default by the new Configurator defaults

H743 support

INAV 4.0 comes with the full support of all H7 boards compatible with MATEKH743 target. This includes the SD Card and MSC mode support. Bear in mind, CAN and UAVCAN are still not supported by INAV and currently, there are no plans to implement them.

Blackbox improvements

Blackbox now always logs the Control Derivative and Feed Forward components, as well as rate target in degrees-per-seconds.
The latest INAV Blackbox Explorer is required to fully use those features.

New command blackbox allows setting which Blackbox fields are recorded to conserve space and bandwidth. Possible fields are:

• NAV_ACC - Navigation accelerometer readouts
• NAV_PID - Navigation PID debug
• NAV_POS - Current and target position and altitude
• MAG - Magnetometer raw values
• ACC - Accelerometer raw values
• ATTI - Attitude as computed by INAV position estimator
• RC_DATA - RC channels 1-4 as returned by the radio receiver
• RC_COMMAND - RC_DATA converted to [-500:500] scale with expo and headband
• MOTORS - motor output

Usage

• blackbox currently enabled Blackbox fields
• blackbox list all available fields
• blackbox -MOTORS disable MOTORS logging
• blackbox MOTOR enable MOTORS logging

Rate Dynamics

INAV 4.0 adds a port of the EmuFlight Rate Dynamics system. It modifies stick input to change the flight feeling. To find out more refer to:

1. https://www.youtube.com/watch?v=8WyJx2FcLzI
2. https://github.com/emuflight/EmuFlight/wiki/Rate-Dynamics

Below are some presets you might want to try

WP Mission Enhancements

Multi-Mission

Multiple missions may be uploaded to the flight controller and a mission selected for execution by OSD, Stick Command or Mission Planner. Multi-Mission is supported by the inav Configurator and mwp mission planners.

Number of Waypoints

The maximum number of WPs is now 120.

On the fly missions

Inav 4.0 adds the capability to generate an "on the fly" mission while flying using aircraft positions.

Fly By Home Waypoints

Inav 4.0 adds Fly-by-home waypoints. This is a way point whose location is set to the home position at arm time.

Fixed wing changes

Soaring mode

Soaring mode comes to iNav 4.0. The addition is great for people who fly gliders. Soaring mode adds a modifier that you can use to change how Course Hold, Cruise, or Position Hold (loiter) behave. When enabled, it disables altitude control and allows Angle mode to free float in pitch, allows the plane to soar freely.

Two-stage climb first for RTH

This change allows the climb phase of a climb first RTH to have two separate parts. This is useful for pilots who want to climb first, to clear potential obstacles. But, don't want to be wasting energy flying away from home. This allows you to set a first climb stage altitude. Once it meets or exceeds that altitude, the plane will turn to home and continue climbing to the RTH altitude. See the iNav Wiki for more information.

Autotune no longer tunes P and I

There were often autotunes in iNav 3.0 which resulted in too high P and I. Also, D was not tuned at all. New default PIDs, that will work reasonably on all sizes of planes (#1390) have been added. This should give good results with an autotune, which can then be fine tuned to your plane.

OSD Units

If you previously used the UK units in your OSD. You will now find that your units are set to Metric + MPH. This is the new name for the old UK units. There is also a new UK units set, that better represents transportation units used in the UK. Full details can be found in the pull release.

There is also a new units set aimed at General Aviation pilots. This set uses Knots, Feet, Nautical Miles, 100 Feet per Minute, and Celsius for their respective values.

Changed Settings

Setting	Description
blackbox_device	Default: target
log_level	Default: ERROR
nav_overrides_motor_stop	When set to OFF the navigation system will not take over the control of the motor if the throttle is low (motor will stop). When set to OFF_ALWAYS the navigation system will not take over the control of the motor if the throttle was low even when failsafe is triggered. When set to AUTO_ONLY the navigation system will only take over the control of the throttle in autonomous navigation modes (NAV WP and NAV RTH). When set to ALL_NAV (default) the navigation system will take over the control of the motor completely and never allow the motor to stop even when the throttle is low. This setting only has an effect on NAV modes which take control of the throttle when combined with MOTOR_STOP and is likely to cause a stall if fw_min_throttle_down_pitch isn't set correctly or the pitch estimation is wrong for fixed wing models when not set to ALL_NAV

Important Notes

F3 Removal

STM32 F3 flight controllers like Omnibus F3 or SP Racing F3 are no longer supported in INAV. If you are still using F3 boards, please migrate to F4 or F7.

The supporting code will be retained for a few more releases, but will not be maintained and is not guaranteed to build or work properly in the future.

Adjustments

There are now separate adjustments for D and CD/FF gains. This breaks compatibility with diffs from previous releases. Check the adjustments tab in the configurator after restoring a diff to makes sure they are set up correctly.

Font update required

The OSD fonts have been improved (@Jettrel) and there are several new symbols. A font file update is required to use the new symbols and avoid an invalid font warning. Upload the updated font of your choosing from the OSD tab.

Upgrading from previous releases

We suggest NOT to do a full diff or dump upgrade. To get the best performance set up your aircraft from scratch. You can copy osd, aux, serial, and mixer settings, as well as accelerometer and magnetometer calibration values from INAV 2.6, but other settings should be tuned again.

dshot_beeper_tone	Sets the DShot beeper tone Values: 1 - 5 Default: 1
fw_d_pitch	Fixed wing rate stabilisation D-gain for PITCH Default: 0
fw_d_roll	Fixed wing rate stabilisation D-gain for ROLL Default: 0
fw_d_yaw	Fixed wing rate stabilisation D-gain for YAW Default: 0
fw_level_pitch_trim	Pitch trim for self-leveling flight modes. In degrees. +5 means airplane nose should be raised 5 deg from level Values: -10 - 10 Default: 0
fw_yaw_iterm_freeze_bank_angle	Yaw Iterm is frozen when bank angle is above this threshold [degrees]. This solves the problem of the rudder counteracting turns by partially disabling yaw stabilization when making banked turns. Setting to 0 (the default) disables this feature. Only applies when autopilot is not active and TURN ASSIST is disabled. Values: 0 - 90 Default: 0
gyro_abg_alpha	Alpha factor for Gyro Alpha-Beta-Gamma filter Values: 0 - 1 Default: 0
gyro_abg_boost	Boost factor for Gyro Alpha-Beta-Gamma filter Values: 0 - 2 Default: 0.35
gyro_abg_half_life	Sample half-life for Gyro Alpha-Beta-Gamma filter Values: 0 - 10 Default: 0.5
gyro_anti_aliasing_lpf_hz	Gyro processing anti-aliasing filter cutoff frequency. In normal operation this filter setting should never be changed. In Hz Values: 0 - 255 Default: 250
gyro_anti_aliasing_lpf_type	Specifies the type of the software LPF of the gyro signals. Default: PT1
gyro_dyn_lpf_curve_expo	Expo value for the throttle-to-frequency mapping for Dynamic LPF Values: 1 - 10 Default: 5
gyro_dyn_lpf_max_hz	Maximum frequency of the gyro Dynamic LPF Values: 40 - 1000 Default: 500
gyro_dyn_lpf_min_hz	Minimum frequency of the gyro Dynamic LPF Values: 40 - 400 Default: 200
gyro_main_lpf_hz	Software based gyro main lowpass filter. Value is cutoff frequency (Hz) Values: 0 - 500 Default: 60
gyro_main_lpf_type	Defines the type of the main gyro LPF filter. Possible values: PT1, BIQUAD. PT1 offers faster filter response while BIQUAD better attenuation. Default: BIQUAD
gyro_use_dyn_lpf	Use Dynamic LPF instead of static gyro stage1 LPF. Dynamic Gyro LPF updates gyro LPF based on the throttle position. Default: FALSE
