Support ExpressLRS

Supporting ExpressLRS is as easy as contributing a feature, either code or just a fleshed out idea. Coding not your thing? Testing a Pull Request using the convenient Configurator tab and providing feedback is essential as well. We're all working together.

If you don't have the time to contribute in that way, consider making a small donation. Donations are used to buy test equipment, software licenses, and certificates needed to further the project and make it securely accessible. ExpressLRS accepts donations through Open Collective, which provides recognition of donors and transparency on how that support is utilized.

Quick Start Guide

If you have hardware that you want to flash, please refer to our guides on the website, and our FAQ

Installation

We provide a standalone program for 64bit Windows, Linux and Mac.

Download the installer from Releases page.

Notes

Windows

The minimum required version of windows is Windows 8.

macOS

Changes to the security model used in the latest versions of MacOS X 10.14 (Mojave) and 10.15 (Catalina) mean that the operating system will show an error message ('"ExpressLRS Configurator.app" cannot be openend because the developer cannot be verified') when trying to install the application.

To work around this, click ExpressLRS Configurator.app while pressing control key, and click Open. In the popup, you'll be able to forcefully open the application. (you may need to try this twice.)

Alternatively, run the following command in a terminal after installing:

sudo xattr -rd com.apple.quarantine /Applications/ExpressLRS\ Configurator.app

Linux

Linux users have to install udev rules for PlatformIO supported boards/devices. The latest version of rules may be found at https://raw.githubusercontent.com/platformio/platformio-core/master/scripts/99-platformio-udev.rules

This file must be placed at /etc/udev/rules.d/99-platformio-udev.rules (preferred location) or /lib/udev/rules.d/99-platformio-udev.rules (required on some broken systems).

Please open system Terminal and type:

# Recommended
curl -fsSL https://raw.githubusercontent.com/platformio/platformio-core/master/scripts/99-platformio-udev.rules | sudo tee /etc/udev/rules.d/99-platformio-udev.rules

# OR, manually download and copy this file to destination folder
sudo cp 99-platformio-udev.rules /etc/udev/rules.d/99-platformio-udev.rules

Restart "udev" management tool:

sudo service udev restart
# or
sudo udevadm control --reload-rules
sudo udevadm trigger

Ubuntu/Debian users may need to add own "username" to the "dialout" group if they are not "root", doing this issuing:

sudo usermod -a -G dialout $USER
sudo usermod -a -G plugdev $USER

Similarly, Arch users may need to add their user to the “uucp” group

sudo usermod -a -G uucp $USER
sudo usermod -a -G lock $USER

Ubuntu 18.XX / Older Debian installs troubleshooting

On Ubuntu 18.XX you are not able to get recent git version by default, and some other system dependencies are missing.

Read more about this in issue #26.

To work around that you can manually install required packages:

# install missing sys packages
sudo apt update
sudo apt-get install gconf2 gconf-service python3-distutils

# install git version >= 2.25
sudo add-apt-repository ppa:git-core/ppa
sudo apt update
sudo apt install git

This Electron application is split into two parts: a local API server that does all the work, and a UI layer. Both of these application layers communicate within each other using Graphql protocol.

Heavy use of TypeScript and @graphql-codegen/cli is made throughout the repository to ensure the datatypes transmitted between the API and UI layers are consistent at compile-time and Graphql ensuring the datatypes are consistent at runtime.

Starting Development

Prerequisites

• node >=16.0
• git >= 2.25
• python >= 3.6
• platformio >= 5.0

Start the app in the dev environment:

yarn install --frozen-lockfile
yarn start

In order to simulate WI-FI devices on your local network you can start application with MULTICAST_DNS_SIMULATOR_ENABLED environment variable:

npx cross-env MULTICAST_DNS_SIMULATOR_ENABLED=true yarn start

Other useful cli commands

Generate TypeScript types from Graphql schema and Queries located in src/ui/gql/queries:

yarn run gql-codegen
