Bluetooth Disconnection After 20 seconds

    I'm having an issue where the bluetooth connection between my MacBook (server) and Thinkpad (client) is disconnected after 20 seconds. This happens every time I initiate a bluetooth connection, and it doesn't matter whether there is keyboard/mouse activity or not.

    • Hardware: MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports, 2.7GHz i7, 16GB)
    • OS: macOS High Sierra, 10.13.6

    • Hardware: Lenovo Thinkpad T490 (i7-8665U, 24GB)
    • OS: Windows 10, Version 1909, OS Build 18363.1316
    • Not running Across client software, just advertising the Mac as bluetooth keyboard/mouse
    Please let me know what information I can provide to assist in troubleshooting.

    This does not happen with other clients.

    Hi Seungjin,

    Thanks for getting back to me.

    I've tried disabling bluetoothaudiod, and also stopping HandOff.

    $ sudo launchctl list /System/Library/LaunchDaemons/com.apple.bluetoothaudiod.plist
    Could not find service "/System/Library/LaunchDaemons/com.apple.bluetoothaudiod.plist" in domain for system

    Neither of the above worked and the issue still remains.

    Unfortunately I cannot roll back to a previous version of Windows, as the Windows laptop is provided by my company's corporate HQ and I do not have local admin privileges.
