Inspiron 3542 (2014) win 10 bluetooth connection

Dear Support,

My subject laptop has 1705 driver with Win 10. Sometimes when I was listening to music by connecting my laptop to a jack output speaker, then trying to switch to another one with bluetooth, it stated on the marked spot (Hungarian), that connection failed.

These times I have to restart the whole system so that it can connect.

How can the connection be stabilzed after switching speakers?

With the 1704 driver my Device Manager does not even list the bluetooth device.

Have a nice day,

Szabi
