ExpressLRS V3.2.1
Getting Started 3.0 Documentation
The important stuff
- Arming must be on AUX1 for safety and feature reasons, having this fixed allows us to maintain small packet sizes and deliver better aux channel options
- Be sure to flash both the TX and RX.
- Lua script MUST be updated to elrsV3.lua and is backwards compatible with 2.x. Get it here: Lua
Compatibility
This is a bugfix release (bug-fixes only, no new targets or features) and is compatible with V3.X.
Who should update from V3.2.0?
- There are minor fixes that benefit all users, so ideally everyone should update, however some fixes will be more important for:
- Users with Skystars SS24D receivers
- Users with Emax 900Mhz transmitter modules
- Users with Radiomaster Zorro, TX12 or TX16S handsets, with internal ELRS modules
- Users within the EU_LBT region
Maintenance
- Hide the 'Reset Runtime Options' button in webui if runtime options are not customized #2053
- Tweak output power values for Emax 900Mhz targets #2126
Fixes
- Fix Skystars SS24D target layout #2078
- Fix "random hangs" when using the EU_LBT region, and a "channel in use" is detected #2055
- Fix issue where some MSP commands would be mistakenly processed by the RX as RX commands #2062
- Fix race condition in Telemetry #2103
- Display the correct UID (the one that is currently being used) in the webui #2112
- Fix the displayed telemetry bandwidth in LUA when using F1000 TLM 1:2 #2118
- Fix "AST node column out of range", python 3.11 support (#2116) #2138
- Fixed an issue that caused RF power to increase past the set limit on TX modules that use the SKY85321 #2142
Known Issues
- Changing the packet rate via the screen + 5way while a link is active between TX and RX may sometimes result in a failure to re-link after the rate change. Reverting back to the previous packet rate will recover the link. The current workaround for this issue is to use the LUA to change packet rates, which is not affected by this problem.

What happened to V3.1.0?
V3.1.0 was pulled as there was a serious upgrade issue for some users on Windows systems. Their TX module or ESP32-based receivers appeared soft-bricked, as they would enter wifi hardware-configuration mode because of an obscure bug in the platformio ESP32 base system which left the flash chip unable to be read by the firmware.
There were also a couple of other bugs found during testing that we really wanted to get fixed.
Compatibility
This is a minor version release (new features, targets and bug-fixes only) and is compatible with V3.X.

Getting Started 3.0 Documentation

- Be sure to flash both the TX and RX.
- Lua script MUST be updated to elrsV3.lua and is backwards compatible with 2.x. Get it here: Lua
Compatibility
This is a new major version, 3.x, and like previous major versions the software is incompatible with the previous major versions, ExpressLRS 1.x and 2.x. TXes running 3.x software only work with RXes running 3.x software-- both sides must be upgraded. SPI RXes all currently run 2.x and will not work with a 3.x TX.
Users of SPI receivers (AIO boards) maintain compatibility with currently available V2 RF modes. Flight controllers can be updated from PR betaflight/betaflight#11783 or wait until merged into BF master.
Packet types and RF smarts
-
FLRC - The F is for Fast (modulation) and lower latency, but a shorter range than our normal modes. Our version can still easily do +10km and comes in 500Hz and 1000Hz flavors #1277
-
Déjà Vu Diversity Aid (DVDA) - On top of FLRC, these modes use multiple sends to create more reliable connection when faced with interference such as at FPV races with many transmitters. 250Hz and 500Hz versions, which do quad and double sends respectively, and across multiple frequencies. #1527
-
More Full Resolution channels (Full) - Instead of just 4ch + 8x switches, support for 10-bit 8ch/12ch/16ch modes in 100Hz and 333Hz rates, using LoRa modulation. #1572
-
LBT - For compliance, listen-before-talk has been added to allow certification of our TX modules in the EU up to 100mW. #1243
-
Increased precision over 2.x modes - 25% better stick precision in the 988us to 2012us range, except for fullres modes. 1 "bit" over-the-air used to represent 1.2us of stick, now 1 bit = 1us. #1572
-
Video: ExpressLRS 3.0 Packet Modes Explained https://youtu.be/ymv9OJFWgJ4
New Features
- Wifi-based Betaflight Configurator through the RX (mobile and desktop versions). #1274
- Loan model - Easily loan your quad to someone else by effectively binding it to their TX from Lua or by bumping for TXes with accelerometers (Axis Thor). #1459 #1510
- Dynamic bind phrase - A loan not enough? Just type a new bind phrase in the web-ui to own the model forever.
- PWM servo output refactored - Allows per-output servo rate (50Hz, 100Hz, 160Hz, 333Hz, 400Hz) and massively reduced update latency over 2.x. #1558
- Lua config for receivers - Currently just telemetry power and diversity antenna select. #1362
- VBAT telemetry for PWM RXes - Not just the Matek converters, built into the native PWM RX itself.
- Lua shows TX Power / VTX Admin settings without drilling down. Current Model ID and Tlm bandwidth shown as well. #1436
- Updated web-ui with tabs and more options. #1604
Functionality changes
- Rewritten Dynamic Power - Uses SNR instead of RSSI to determine appropriate power, as RSSI doesn't factor in the noise floor or if the RX has an amplifier. Also reacts faster, needing just a single telemetry packet to make a decision, and preemptively steps up power when missing packets instead of waiting to jump to full. Also will lower power if overloading the RX at close range.
#1529 - "Standard" telemetry ratio - Automatically picks a basic ratio for the selected packet rate, which means it will pick a “good default” for the packet rate selected. #1599
- "Race" telemetry ratio - Same as "Standard" except disables telemetry and SYNC packets when armed (replaces NO_SYNC_ON_ARM). #1599
- New (factory defaults) transmitter modules now default to 250Hz for Team2.4 #1815
Minor enhancements and fixes
- New Lua file name: elrsV3.lua (V3 LUA also works with 2.x firmware as well)
- Display warning message when baud too low for the selected RF mode #1672
- Long-press the button on receivers to reset RX config #1681
- Reduce handset sync margin - Reduces latency for all RF Modes by 0.3ms #1532
- Increased telemetry bandwidth - Makes things like RxBt and GPS position update more frequently.
- TX modules will not start transmitting until they receive a ReceiverID command from the handset, or at least 5s from the first received channels packet. This prevents syncing using ModelID 0 on boot #1775
- Lua: Update sensitivity while changing packet rate #1808
- Lua: Don't pause updating while in edit mode #1809
- Lua: Support touch events on popups, reduced code size #1753
- Safer updating of SwitchMode on the RX instead of ignoring it #1792
- Adjust VBAT scaling for 6ch PWM RX #1724
- Fix difficulty flashing Betaflight passthrough where target name was reporting a number #1708
- Allow TX to function with a failed accelerometer #1698
New targets
- TX12 Target #1738
- EMAX OLED TX and RX #1787
- Foxeer RX #1796
- HappyModel EP1 Dual RX #1821
- Unified ESP targets - Our internals are now set up to produce just one firmware image for all devices of the same type (all ESP32-based TXes, all ESP8285 RXes and now ESP32 based RXes)
#1552 - Integrated VTX - New receivers with the VTX combined on a single MCU, similar to the Happymodel Fyujon, but without the extra MCU for the VTX side. This will allow for AIOs with serial RXes, rather than SPI, thanks to us taking over the VTX duties and only using a single UART. Keep an eye out for the next generation of ExpressLRS AIO’s from your favorite manufacturers in the near future.
Manufacturers and DIYers can find reference designs here #1607 - True diversity receivers with optional integrated VTx - working with manufacturers currently to make these
Manufacturers and DIYers can find reference designs here #1555 (comment) - Receivers with more PWM outputs - working with manufacturers currently to make these, 6ch, 8ch and 10ch at least in pre-production
- Use any (ESP8285) receiver as TX - Just for DIYers really #1457
Known Issues
- On performing WiFi updates to some TX modules you may get a “Bad Size Given” error. If you get this error, it can be remedied by either flashing via UART, or flashing the repartitioner from https://github.com/pkendall64/repartitioner/releases/download/1.0/repartitioner.bin then reflashing via wifi after it has completed.

A note on versioning
The versioning scheme chosen by the ExpressLRS devs is based on the semantic versioning scheme.
Where a version is defined as “major.minor.patch”
major = major new feature and/or incompatible changes
minor = minor features or enhancements and/or new targets
patch = bug-fixes
