Toggling Your Bluetooth Connection using
bluetoothctl on the Command-Line
Since getting a pair of Bluetooth headphones, I've been thoroughly enjoying being able to be hands-free.
However, one thing that's annoyed me is that to switch between my desktop (where I play my music on) and my work laptop (for Zoom calls), which requires either clicking around in UIs, or running a couple of invocations of command-line, none of which is useful if I need to quickly switch between them.
bluetoothctl, there's no way to determine if the controller is connected to any device, but given we know the MAC address for the device, we can use the
info subcommand and determine if it's connected:
if bluetoothctl info "$device" | grep 'Connected: yes' -q; then
bluetoothctl disconnect "$device"
bluetoothctl connect "$device"
This will now toggle the connection of the device.
