ExpressLRS V1.0.0 RC5 Release

ExpressLRS V1.0.0 RC5 Release

Thanks to all the testers and reports, If on previous release candidate please update ASAP to avoid potential failsafe issue (#553).

Change Log:

• Code reorganization and several bug fixes to address Issue #553 (sudden failsafe on Team900 with RX lockup) PR#594
• Reduce minimum LQ required to connect an RX from 75 to based on number of FHSS channels
  • Team2.4 - 5
  • FCC915 - 5
  • AU915 - 9
  • EU868 - 9
  • EU/AU433 - 37
• Increase power output on Ghost Lite TX which did not have its power amplifier on at all
• Fix via_Betaflight bricking ESP8266 RXes when flashing through iNav (EP1, EP2)
• Force DIVERSITY disabled on EP1, EP2 RX which do not have diversity hardware
• Enable missing interrupt priorities on FM30 hardware for tighter timing
• Add -DDISABLE_STARTUP_BEEP to disable TX startup melody
• Add DIY TX_1280_Minimal TX PCB design

1.0.0-RC3

ExpressLRS V1.0.0 RC3 Release

As always, 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

Another week, another RC., Thanks to all that tested and reported bugs with RC1 and RC2. Update to RC3 through configurator or VScode, no special updating precautions are required. Bootloaders all remain the same.

As always please report any bugs and issues found.

This weeks changes and improvements are:

• Enable via_BetaflightPasshthrough for ESP8266 targets (will work after you update to RC3)
• No longer count telemetry packets which previously artificially inflated RX LQI a small amount
• Fix unable to manually bind when TX already set to highest rate
• Fix unable to manually bind without enabling ENABLE_TELEMETRY
• Lower HappyModel 2.4GHz output power (was 1-2dBm too high)
• Fix possible loss of RX binding information or crash on startup due to not correctly initializing EEPROM
• Lua - Don't display bogus version mismatch error on starup
• Lua - Add telemetry bandwidth to display

1.0.0-RC2

ExpressLRS V1.0.0 RC2 Release

As always, 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

Thank you to all that tested and reported bugs with RC1, update to RC2 through configurator or VScode, no special updating precautions are required.

This V1.0.0-RC2 release has the following changes and bug fixes:

• Fixed critical bug with LOCK_ON_FIRST_CONNECTION not working as intended

  • LED blinks when disconnected and LOCK_ON_FIRST_CONNECTION is active

• Improved initial sync behaviour, syncing at lower pkt rates should be faster and more reliable

  • Removed FAST_SYNC option (deprecated)

• Fixed RGB led on Ghost atto/zepto target

• Fixed crash in neopixel LED library.

• Fixed advanced telemetry not working on 1:128 or 1:64 telemetry ratios

• Tuned power output for NamimnoRC TX

• Updated super slim case and PCB files

• Added t-lite PCB

• Minor readme edits

1.0.0-RC1

ExpressLRS 1.0.0-RC1 Release Notes
