“ELRS is great, but the first-time setup was a PITA!” This is one of the main complaints we see across the groups about ExpressLRS.

We understand the challenges faced during the initial setup process of ExpressLRS, with many users expressing their frustration. In version 1.4, we are doing something to improve this, starting with the introduction of pre-compiled builds.

While our "just-in-time" firmware compilation approach has served us well in the past, it has also caused inconvenience and frustration. Various factors, some of which were completely out of our control (e.g. updates to the Platformio framework), have resulted in failed configurator builds, leading to user dissatisfaction.

To overcome these challenges, we have made a significant change in v1.4. Instead of relying on local compilation for release versions, the configurator will now seamlessly retrieve pre-built firmware from the cloud and flash it onto your device. This shift not only drastically reduces firmware update times from minutes to seconds but also eliminates many annoying build issues, where users are faced with the dreaded red "failed build" error message in the Configurator.

Make sure you have updated to version 1.6.0 the Configurator to take advantage of this awesome new feature: https://github.com/ExpressLRS/ExpressLRS-Configurator/releases

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
