ExpressLRS v3.5.0 RC1 and Backpack v1.5.0 veröffentlicht
ELRS ist in der Version 3.5RC verfügbar und bietet viele neue Features
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.
- This is a release candidate. We have tested it using our release test plan, but there may still be bugs. Don’t flash it to anything important. We appreciate the community testing.
- Lua script MUST be updated to elrsV3.lua and is backwards compatible with 2.x. Firmware get it here: Lua
Compatibility
This is a minor version release (which means it contains new features, targets and bug-fixes only) and is compatible with any other hardware that is running V3.X.
Who should update from V3.4?
- Anyone who is interested in the latest and greatest features listed below.
Announcement
ELRS V3.5 will be the last release to support STM32 based hardware. This includes the Happymodel PP, ES915 Tx and Rx, early NamimnoRC Flash and Voyager, FrSky, SIYI and IMRC hardware.
New Features
NOTE: More detail on the below features will be added with future RCs and the final release.
MAVLink Support for ELRS #2753
Native MAVLink support allows for direct communication between MAVLink-compatible devices via ExpressLRS. Monitor real-time telemetry in Mission Planner, upload waypoint missions, change parameters while airborne, and control your craft all at the same time via the same low latency RC link. MAVLink-RC also converts telemetry to CRSF on the handset so that your sensors in EdgeTX work as expected #2808.
Independently tested out to 126 km of range without failsafe, MAVLink-RC guarantees a reliable, stable and cost effective solution for our MAVLink users.
More information including setup can be found at https://www.expresslrs.org/software/mavlink/
Enhanced Backpack Support
Complimentary to MAVLink-RC, the Backpack system now forwards telemetry data in a range of different flavors, including MAVLink via WiFi. This is especially beneficial for complex setups where telemetry data is critical.
FSK Modes #2789 #2832
That’s right, ELRS has added FSK support in the form of ‘K’ modes for both SubGHz and 2.4 GHz. The maximum packet rate for the SubG band now jumps from 200Hz to a blistering 1000Hz! With the addition of Forward Error Correction (aka self healing packets) being built into the 2.4 GHz band for increased performance in noisy race environments.
Add native SmartAudio and TRAMP VTX support #2836 #2835
Limited support for SmartAudio and TRAMP VTXs has been integrated, allowing direct control through ExpressLRS receivers.
ESP32 C3 RX support #2610
Native support for ESP32 C3-based receivers has been introduced, expanding hardware compatibility and offering more options for users building or configuring their systems. The C3 is a replacement for the ESP8285 on new receiver hardware from ELRS V3.5.
Add linkstats to module display #2843
Link statistics are now available directly on the module screen. From the home screen users can press down to monitor critical link parameters, signal strength and packet loss in real-time without needing additional tools or interfaces.
Add optional secondary serial device to ESP32 receivers #2605
An optional secondary serial device has been added to ESP32 receivers, increasing the flexibility and customization potential of their setups. This is particularly useful for setups using external sensors such as HoTT.
LR1121 RF Switch Configuration; for simpler hardware designs. #2824
The LR1121 can fully control the signalling to power amplifiers and switches taking the burden off the main MCU.
LR1121 firmware upload. #2825
The LR1121 is firmware upgradable for new features and bug fixes; so we’ve added the ability to upload these directly into the web UI of LR1121 based devices.
LR1121 Continuous Wave testing; #2709
So we can ensure that hardware meets the highest of standards and will all seamlessly connect with each other.
Allow flashing an RX as a TX #2826
Receivers can now be flashed as tiny transmitters allowing users the flexibility to experiment with early release hardware. Or install tiny transmitters in custom handsets.
Other Notable Features
Add bleJoystick as a button event #2842
RX LUA: Make (SBUS) Failsafe Mode line visible #2787
Handset Communication Optimizations #2772
Binding Storage Returnable #2744
Add extra lines for larger screen (e.g. Jumper T15) #2717
Adds betaflight passthrough flashing for S3/C3 #2714
Adds RX fan support #2492
Check file type being uploaded #2756
Fixes
- Remove two sources of telemetry startup hangs #2839
- Downgrade wifi power for 8285 based devices #2848
- Fix LR1121 binding compatibility #2884
- Fix disabling of wifi-auto-on-internal #2897
