xiota [1] filed a deletion request for ts-bt [2]: Package is for maintainer's personal project, which has not been updated since 2016. Maintainer also did not update the package or respond to a comment from over a year ago. This package builds the git master branch, but is missing the -git suffix. There does not appear to have ever been a stable release. There are other defects, like missing `pkgver()` and broken depends.
This package should be deleted. Then if still interested, the maintainer can update the package and resubmit with the suffix correct name. [1] https://aur.archlinux.org/account/xiota/ [2] https://aur.archlinux.org/pkgbase/ts-bt/
