How to block bluetooth device that auto connect

[glpi-ios]

Hi,

A bluetooth device that is not mine try to connect on my MacBook pro every minutes.
This has the consequence of disconnecting me for a few seconds from my bluetooth devices.

I've tried - Disable Bluetooth

• Delete "com.apple.Bluetooth.plist" from "Library/Preferences" and "ByHost" folders

• plutil -convert xml1 /Library/Preferences/com.apple.Bluetooth.plist

• Add this section to the plist:
  <key>IgnoredDevices</key>
  <array> <string>MAC ADRESS</string>
  </array>

• sudo plutil -convert binary1 /Library/Preferences/com.apple.Bluetooth.plist

• Reboot

• Enable Bluetooth

But my changes to this plist get reverted back and the device appears again.

Please, can you help me...

MacOS 10.13.6 / Jamf 10.6.0

Thanks

Dated post, so you've probably solved the issue?? If not, I would suggest an nvram reset, either holding the command option p r keys on startup, or in the Terminal: nvram -xp & reboot.
