Hello and welcome to INAV 9.0.1 Please carefully read all of this document for the best possible experience and safety. Contact other pilots, share experiences, suggestions and ask for help on: INAV Discord Server INAV Official on Facebook This is a patch release with bug fixes and new target support. No settings have been renamed or removed, so your 9.0.0 configuration will work without changes. Changes since 9.0.0 Bug Fixes CRSF frame length validation - Fix missing frame length verification when handling CRSF_FRAMETYPE_MSP_REQ/MSP_WRITE, preventing potential buffer issues (#11210, @VoodooChild99) Position estimator corrections - Fix position and velocity corrections for improved GPS hold and navigation accuracy. Addresses issues #10360, #10391, #10893, #11049 (#11270, @breadoven) Position estimator sanity limit - Relate correction sanity limit to loop rate for consistent behavior across different loop rates (#11270, @breadoven) STM32H7 DFU mode - Fix CLI dfu command on H743/H750 targets which would reboot as VCP instead of entering DFU mode (#11295, @sensei-hacker) DShot beeper arming loop - Fix feedback loop where DShot beeper confirmation prevents re-arming by resetting the guard timer on each attempt (#11306, @sensei-hacker) Surface mode Z velocity - Fix mathematical inconsistency where AGL velocity update used squared acceleration weight factor while altitude update used linear weight factor (#11255, @sensei-hacker) Terra Ranger Evo - Fix rangefinder driver for TeraRanger Evo sensors (#11311, @error414) New Targets AIKONF4V3 - Aikon F405 V3 flight controller (#11284, @sensei-hacker) COREWINGF405WINGV2 - CoreWing F405 Wing V2 (#11291, @MakeSomeFakeNews) Build & CI PG struct validation - Add build-time Parameter Group struct size validation to catch EEPROM-breaking changes before release (#11283, @sensei-hacker) Upgrading from INAV 9.0.0 Download and install the new INAV Configurator 9.0.1 Backup configuration with CLI diff all command Flash INAV 9.0.1 - Full Chip Erase is not required when upgrading from 9.0.0 Restore your settings from CLI or select Keep current settings from the defaults pop-up ⚠️ Important Upgrade Information (from INAV 8.x) Flashing Notes Full chip erase REQUIRED when upgrading from 8.x Back up your configuration with diff all before flashing Review 9.0.0 Release Notes for breaking changes and incompatible settings Upgrading from INAV 8.0 Download and install the new INAV Configurator 9.0.1 Backup configuration with CLI diff all command or use the Diff All and Save to file buttons. Flash INAV 9.0.1 WITH Full Chip Erase option enabled Load your 8.0 Diff settings in to the CLI. Then take a note or write down the incompatible settings changes marked in RED. Then copy your 8.0 Diff file and rename it 9.0. And edit the old incompatible settings. Go to CLI and load your edited INAV 9.0 Diff Done Tip Concerning step 6. It can be a safer option to load your Diff All settings in two parts if you are using multiple Profiles. e.g. Control, Mixer or Battery. This can be done by copying and loading the Diff All text setting from the top, down to the bottom of the # master settings category. Then load that into the CLI and press enter. Once it has written, press the Save Settings button. Wait until it reboots and go back to the CLI tab again, then copy and load the rest of the Diff All text file. Starting from the # Control_profile 1 settings category, down to the bottom. Press enter. Once written, it will save by itself. Diff update tool Rather than steps 4 and 5 above. You can try this diff update tool. This is a work in progress. Currently it will try to update version 7 or later diffs to version 8 or later. Just paste your full diff all (not dump) in to the tool. Select the INAV version you're upgrading to. Then press the button. It will create a new diff for you and give you warnings about anything you should check.

Compatibility Not compatible with ExpressLRS 3.x.x, 2.x.x, or 1.x.x. ExpressLRS major versions are not cross compatible therefore this version 4 OTA is incompatible prior versions and will not connect at all (theoretically). Support for STM32-based hardware has been removed, including all R9M hardware, your ExpressLRS PP, and Ghost devices. NDAA Blue can eat our shorts. Fullres packet modes users in 8ch and 12ch mode will find CH9 or CH13 missing, and Arm moved to CH14. See "Optional Arming Method" below. Any custom hardware.json and options.json (set from the webui Options tab) will be lost due to the flash filesystem update, back them up before updating. See "Flash Filesystem Changed". Highlights Automatic Antenna Modes Stop babysitting your receiver antenna modes. Updated RX/TX syncing now automatically select between True Diversity and Gemini mode based on the transmitter setting so you don't have to. If you connect to a single RF chip receiver, the transmitter also automatically steps down from Gemini mode to antenna switch mode. Optional alternative arming method (requires EdgeTX 2.11.0 or higher) The alternative arming method doesn’t use CH5 to communicate the user’s arming request to the TX module leaving CH5 free to use as a regular control channel. Arming is performed by user selected sources, e.g. physical or logical switches, anything EdgeTX offers as a source really. The alternative arming method works for all packet rates and switch modes but is especially useful for the fullres packet rates in connection with PWM receivers. No more “remapping CH5” required to use CH5 as control channel. The optional arming method can be enabled in the EdgeTX Internal/External RF Model Setup menu by changing “Arm using” to “Switch”. Due to this change, fullres modes no longer "skip" CH5. Previously, 8ch and 12ch modes would generate 9ch or 13ch but now generate exactly the number of full resolution channels specified and CH5 is always a full channel. Users may shift CH6+ down by one or use a higher channel count to account for the change. CH14 now carries the 1 bit arming flag in 8ch and 12ch mode. Expanded PWM receiver output offerings You bought the whole servo, use the whole servo, available servo stretch mode now extends the channel input to 500-2500us output Failsafe ranges have been extended to 476-2523 allow you to failsafe wherever you want on the dial DSHOT 3D mode added as an available output option Statistical Adaptive Dynamic Power Instead of fixed SNR values compiled into the firmware, the dynamic power system now statistically models the SNR expected to result in 99%+ LQ and adjusts power to achieve that. This majorly improves dynamic power for LR1121 systems, which in 3.x tend greatly toward full blast output. Now it goes up, up, up, for a moment... but you're gonna be, gonna be golden. New WebUI New modern WebUI with an updated look and beautiful organized code instead of a pile of javascript that didn’t even have any consistent whitespace. Improved telemetry bandwidth Double telemetry bandwidth when operating in Gemini mode. We're putting eggs in every basket now. Instead of redundant packets, the telemetry downlink now sends data across both Gemini packets, doubling the telemetry bandwidth. All my single ladies aren't left out either. OTA rejiggering means improved telemetry bandwidth for all non-Fullres packet modes too. Std telemetry rate on 500Hz shows a 30% increase in bandwidth, reducing the time to receive 14 Betaflight telemetry items from 6.6s to 5.1s. Combined with the Gemini telemetry change, this provides 66% additional improvement, from 5.1s to 3.1s. Headtracking tracking more than heads Headtracking through the backpack now supports sending the data to EdgeTX instead, and an arbitrary number of channels. Designed for wireless connected pedals (available now) and built in wireless trainer mode (future). New DJI output protocol Slap that DJI Air Unit out of low power mode without needing a flight controller. ExpressLRS now has the ability to arm DJI air units, either tied to arm state or permanently on. New input telemetry protocols supported A NMEA-output GPS can now be attached directly (115200 baud) for sending position, ground speed. Altitude, and satellite count. HoTT telemetry has been extended to support the VSpeak turbine protocol including RPM, fuel level and flow, EGT, ECU voltage, pump and throttle % and status. (Image credit: StartZero100) More robust syncing The OTA now requires a counter synchronization lock to function, ensuring that TX and RX share a consistent state. There were certain cases where you could start a connection, but the Link Quality would stay very low (10-20%) even at close range. Instead of this failed sync going on indefinitely, the connection can no longer progress without proper sync and the RX will automatically retry the connection. Solves the “radio off to check failsafe” issue where sometimes the receiver behaved erratic after re-connect. Making our code less garbagey Core code refactors mean our interface is more CRSF spec compliant, and a new CRSF packet routing system allows data to move data between more than just a handset and flight controller. There's an expanded event flags system and other framework optimizations for the internal device framework that runs peripherals. STM32 support has removed, and our platforms and libraries have been updated to the latest versions. Expanded packet modes for LR1121 The whole reason 4.0 needed to happen! The new sync structure means being able to support more packet modes. LR1121 gets more, up to a staggering 20 packet modes. The Team900, Team2.4, and GemX modes are also no longer mixed in one list and are selectable by band. New modes: K1000 2.4 ➡️ 1000Hz FSK (module baud rate must be 921k or higher) DK250 2.4 ➡️ 250Hz DVDA FSK D50 LoRa 900 ➡️ 50Hz DVDA 25Hz LoRa 900 ➡️ 25Hz LoRa 900 Flash Filesystem Changed The internal flash filesystem has been changed from the deprecated SPIFFS to LittleFS. There is no way to upgrade the filesystem in place. This means custom changes made on the old hardware.html page will be erased during the upgrade, along with items from the Options tab in the webui (receiver baud, airport, wifi and regulatory domain overrides, etc). The hardware.json can be downloaded from the webui before updating and then replaced after updating. PWM mappings and serial protocols are not affected. Minor changes Backpack is now disabled in wifi and BLE modes Wide switch mode is always 6-bit now instead of switching between 6 and 7 bit modes, returning boost telemetry performance back to levels before 3.5.4 TQly telemetry item now samples the last 100 telemetry receives, up from 25 Reduced jitter in receiver serial output by always sending synced with the packet timer instead of at packet reception time. Linkstats are always sent to the handset, even when disconnected. This allows a more immediate notice if the TX believes telemetry has stopped, and in the future we hope this will allow EdgeTX to display more TX status information while disconnected. Lua r16 - Now labeled elrs.lua, contains bugfixes but old r15 or whatever is on your handset is probably fine.
