Unfortunately, it did not help — LE devices are still not detected (either at all or after one-two successful pairings). Seems I managed to reproduce: https://gist.github.com/Vudentz/0988a78da9e5658a06edec159847db27 Looks like ax201 is not generating SCAN_RSP for some reason, will need to follow up with Intel firmware folks to see what is going on. -- Luiz Augusto von Dentz
