OpenTX version 2.3 Discussion Thread

openTx has introduced a range of new features, ideas and bling. It is fast becoming the firmware of choice for many users. openTx will run on ALL current hardware platforms, including the gruvin9x and sky9x boards. Work has already started to support the new FrSky X9D radio!

OpenTX version 2.3 Discussion Thread

Post by pafleraf » Wed Aug 28, 2019 7:15 am

Good morning everyone!

As we are moving forward towards the 2.3 release, more tests are needed. As of now, all the supported targets have been opened to the nightlies and it seems we already have something working quite nicely.

There are still a couple of minor things to come, but the binary format is now settled, Companion and all the radio firmwares should be working with it (including proper conversions from 2.2.x). The times have come to now fix everything we can find and finalise the release.

As this is still in beta state, it is a good idea to backup everything you have on 2.2 before testing on the 2.3 branch. For those already on nightlies (new radios), doing backups is still a good idea, so you can always revert to the previous working state in case something slips through the QA.


Please remember that you have to configure "Use nightly builds" in Companion (Settings / Application settings).
