Mac – Bluetooth Automatically Pairs with “Broadcom Bluetooth Device”

I'm experiencing a very annoying issue (Mojave 10.14.1).

When I am staying at a hotel (which I do frequently for work), my computer constantly pairs with devices called "Broadcom Bluetooth Device". It doesn't just discover them – it automatically pairs with them and immediately interferes with legitimate connections to my AirPods or other bluetooth headphones. It breaks and chops the audio into complete, unintelligible, stuttering uselessness.

I have to manually disconnect these things every 1-2 minutes.

I've looked for a few solutions:

• One mentions turning Handoff "off". My Handoff is, in fact, off.

• Another mentions that this issue only crops up when a browser window is open; this happens to me regardless.

• Another mentions using Terminal to 'sudo write' the DontPageAudioDevices value in the bluetooth .plist file in my library to '1'. I have done this, and it fixed the problem partially: the connections to this device have become less frequent, and my computer will automatically disconnect after a few seconds, but usually not quick enough to prevent it from disrupting my audio just the same.

I'm running out of places to treasure hunt for a solution. I don't know why my computer is so stubbornly determined to connect to these random, unknown devices to the point of disrupting fundamental user experience.

Does anybody have a legit solution to force my computer to cease this behavior? This seems like a massive bug that doesn't have a lot of attention. Any help is appreciated.
