this old macos /older mac does it still have the option to reset the BT module..(?)

Hold the Shift Option Keys and click open the BT icon in the Upper right menu bar>Debug>

"Remove All Devices" and "Reset All Devices"  and "Reset the BlueTooth Module"

you can always try —

reset NVRAM/PRAM Reset NVRAM on your Mac - Apple Support

and

Reset the SMC How to reset the SMC of your Mac – Apple Support

To trouble shoot further you can:

—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account. 

—A SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
