You have to be more specific. Output of pastekodi would help here.
Kodi of Orange Pi one plus H6,is 19 alpha?I have problem with pvr addons...Dependence error
This is all pre-alpha. At this point addons can be broken at any point. And no, there is no stable image yet.
That works, but is there a cleaner way to make it work out of the box by now?
No, I made a PR for that but it has several issues (doesn't work in all cases and should be done with udev instead of services). I guess best solution would be to develop some kernel and U-Boot patches, so BT MAC gets set same way as ETH MAC.
