We are working with Actility togather to support LLR on RAK2245 Pi HAT recently. It will take some time to release.
It may work on RAK831 too, but we need to test it on RAK831 after we get the release version.
In fact, this project is developing by us and Actility, but i can’t give out the timeline for the final release, because i can’t control the progress of Actility. I’ll contact with Actility to urge them to complete ASAP. When we release it finally, i’ll reply you in this topic at the first time.
