Why has my bluetooth timed out?

AC Question

bluetooth timeout

I have an Android model K90 tablet running version 4.4.4 operating system.
My problem is my Bluetooth connection. If I don't send anything to my speaher, after about a minute the connection is broken. The speaker beeps, and the tablet reverts to its internal speaker.
I have several other tablets/telephones, and they maintain connection much longer.
There is probably a setting somewhere for me to change, but I have not been able to find it.
Thanks for any help you can offer.
