ExpressLRS V2.0.0 Release Candidate 2
https://www.expresslrs.org/2.0/quick-start/getting-started/
Changes since 2.0.0-RC1
- Prevent going to 1:2 ratio when disconnected and entering Lua (#1092)
- Do not process start wifi on stm32 (#1099)
- Use two param popupConfirmation on FreedomTX (#1096)
- No reason to clear IRQ flags manually (#1086)
- Fix LUA render on NV14 (#1091)
- Shorten Namimno OLEDs to 15 chars (#1093)
- Prevent crash when using BACK item when lua is reloading (#1080)
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 for 2.0RC2, and is not backwards compatible with 1.x. Get it here: LUA
- Users of SPI receivers (AIO boards) must not update until ELRS SPI 2.0 is available, as the protocols are incompatible.
- This is a RELEASE CANDIDATE, and is not guaranteed to be stable or bug free. Test at your own risk! Bad things might happen!
- The user notes below are a concise version of the new features and fixes. Once the final release has been cut, these will be expanded to explain each feature in detail. For now, testers are expected to research within the relevant pull request links, and be prepared to use documentation that is not yet complete

ExpressLRS V1.2.0 Release
ExpressLRS V1.2.0 Release Notes
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
expresslrs.org/quick-start/
Enhancements
- NA
Bugfixes
- For Happymodel EP receivers that take multiple plugins to start, with a "dim LED" or "solid LED for 3-10 seconds before starting to blink", a software workaround for the underspec regulator on those devices (labeled
SDG) allows most to function as proper receivers. Contact HappyModel for replacement options if you have a receiver with this regulator.
#929 - Fix for LQ dropping to 75 then 50 then 25 (nonce slip bug) when using ‘no sync on arm’ due to a bug in the TX code. This may also happen when sync is used but not noticed since the link will usually self-heal.
#946 - Fix intermittent crash-reboot when starting TX module #897
- Telemetry was sending more Advanced Telemetry (Betaflight telemetry items) than it should have, resulting in fewer LinkStatistics telemetry being sent
#905 - Fixes RX communication with KISS V1. Select UART_RX_SPEED_400K in the Configurator. #959
