Selective Bluetooth connection

[Grayarooney]

Recently my phones bluetooth has become very selective, only connecting to some and not all devices, it will not connect to some of its previously paired devices. 

As we are unable to clear cache and data directly from the app, I cleared cache by connecting my phone to my laptop and held down the two buttons and did it that way, this has made no difference at all.

Im avoiding a full factory re set but cant think of anything else to try.

Can anybody help?

Have you tried Settings > General management > Reset > Reset Wi-Fi and Bluetooth settings. Note: You'll need to reconnect your devices/networks.

Also- go to samsung members app- support- diagnostics. Make sure it passes

Have done both of the above, even passes the diagnostics, but just won't connect to some, one being my truck which means no phone in truck.
