On didDisconnectNotif:notif forDevice:dev Set disconnectionNotifObj to (dev's registerForDisconnectNotification:me selector:'didDisconnectNotif:forDevice:') If (dev's nameOrAddress() as text) contains myKeyboard then Set connectionNotifObj to IOBluetoothDevice's registerForConnectNotifications:me selector:'didConnectNotif:forDevice:' Property disconnectionNotifObj : missing value Property connectionNotifObj : missing value Property IOBluetoothDevice : class 'IOBluetoothDevice' Copy the following script into Script Editor: use AppleScript version '2.4' - Yosemite 10.10 or later That way your app will sleep quietly in the background until it gets a notification that a device has been connected or disconnected. That would look like this: property lastStatus : trueīut set all that aside, because I think the best solution is to use the IOBluetoothDevice methods for registering observers. I'll add that it's far better to use an idle loop than an endless repeat loop. I suspect the problem is that you didn't add parentheses to some of your objC methods, specifically: nameOrAddress() and isConnected().

When it fails to detect the reconnect, it is still matching my keyboard name in the pairedDevices() list, just not as connected. If (device's nameOrAddress as string) contains substring thenĮdit: I have inserted lots of debug log messages in various places. Repeat with device in (current application's IOBluetoothDevice's pairedDevices() as list) If kbStatus is not equal to lastStatus thenĭo shell script '/usr/local/bin/ddcctl -d 1 -i 27'ĭo shell script '/usr/local/bin/ddcctl -d 1 -i 17' Set kbStatus to isDeviceConnected(myKeyboard)

If it matters, I'm on Catalina (10.15.7) on a 2019 MacBook Pro. However once the keyboard has disconnected and later reconnects it never detects the connected state again. When I export it as an App (with Run-only) and run it, it starts out detecting the correct state. When I run it in Script Editor it detects both connected and disconnected states as I switch back and forth. Based on I am using the IOBluetooth framework to detect disconnect/reconnect of my keyboard, such that switching it to a second host triggers changing the display input to that host as well.
