How do I disable bluetooth discoverability without just shutting off the bluetooth?

A

AC Question

I paired with speakers in my classroom. I don't want to be paired because my calls are playing over the speakers. So I unpaired them from my device. Now every 30 seconds it pops up and says type in passcode and pair with speakers. I don't want to shut off my bluetooth everytime I'm in class. I forget to turn it back on when I'm in the car. I want my phone to stop discovering bluetooth devices and asking me to pair, unless I want to discover a device.

I already went into settings and shut off "Nearby device scanning". It still does it anyway.
