Through ESP-IDF? Which version?

The latest, but it was a few months ago. The results were off by 50 meters or so, and many persons have the same problems : https://github.com/espressif/esp-idf/issues/8976

Damn! That’s good to know, we’ll be tackling that on our board soon. Wonder what’s causing it? Driver bugs is my guess

Edit: hah if I read the GitHub link, my guess was right. Seems they have a patch there for you to try? Fingers crossed they fix it
