An Applescript to connect bluetooth devices, such as Airpods. Nice when paired with an alfred trigger.

use framework "IOBluetooth"
use scripting additions

set AirPodsName to "AirPods"

on getFirstMatchingDevice(deviceName)
	repeat with device in (current application's IOBluetoothDevice's pairedDevices() as list)
		if (device's nameOrAddress as string) contains deviceName then return device
	end repeat
end getFirstMatchingDevice

on toggleDevice(device)
	if not (device's isConnected as boolean) then
		device's openConnection()
		return "Connecting " & (device's nameOrAddress as string)
	else
		device's closeConnection()
		return "Disconnecting " & (device's nameOrAddress as string)
	end if
end toggleDevice

return toggleDevice(getFirstMatchingDevice(AirPodsName))

An issue I encountered is that if the AirPods are named, that nickname is not expressed in deviceName. So, the bluetooth device is properly found, but SwitchAudioDevice is unable to match against the bluetooth device name.

As a more robust solution, you can have SwitchAudioDevice find the device via it's address string rather than pure name, which not only makes the script run much faster, but fixes the above problem!

use framework "IOBluetooth"

set AirPodsName to "AirPods Pro"

on getFirstMatchingDevice(deviceName)
	repeat with device in (current application's IOBluetoothDevice's pairedDevices() as list)
		if (device's nameOrAddress as string) contains deviceName then return device
	end repeat
end getFirstMatchingDevice

on toggleDevice(device)
	set deviceAddress to quoted form of (do shell script "echo" & (device's addressString as string) & " | tr [:lower:] [:upper:]")
	
	if not (device's isConnected as boolean) then
		device's openConnection()
	end if
	
	with timeout of 10 seconds
		set successfulConnection to false
		repeat while not successfulConnection
			set output to do shell script "/opt/homebrew/bin/SwitchAudioSource -u " & deviceAddress
			set successfulConnection to output contains "output audio device set to"
		end repeat
		
		return "Connected " & (device's nameOrAddress as string)
	end timeout
end toggleDevice

try
	return toggleDevice(getFirstMatchingDevice(AirPodsName))
on error e
	return e
end try
