- Device Discovery: Scan for nearby Bluetooth devices.
- Pairing: Pair with Bluetooth devices.
- Connecting: Establish a connection with paired devices.
- Trusting: Mark devices as trusted to allow automatic connections in the future.
- Agent Management: Manage Bluetooth agents, which handle pairing requests and PIN/passkey entry.

Pair and Connect a Bluetooth Device
$ dzdo bluetoothctl pair <device MAC> $ dzdo bluetoothctl pair D6:A3:C1:F9:2C:21 Attempting to pair with D6:A3:C1:F9:2C:21 [CHG] Device D6:A3:C1:F9:2C:21 Paired: yes Pairing successful
Once the pairing is complete, you need to connect the Bluetooth device:
$ sudo bluetoothctl connect D6:A3:C1:F9:2C:21 Attempting to connect to D6:A3:C1:F9:2C:21 Connection successful
Trusting a Bluetooth Device
If the pairing failed due to error "AuthenticationRejected", you may have to trust it first:
$ dzdo bluetoothctl pair D6:A3:C1:F9:2C:21 Attempting to pair with D6:A3:C1:F9:2C:21 Failed to pair: org.bluez.Error.AuthenticationRejected $ dzdo bluetoothctl trust D6:A3:C1:F9:2C:21 [CHG] Device D6:A3:C1:F9:2C:21 Trusted: yes Changing D6:A3:C1:F9:2C:21 trust succeeded $ dzdo bluetoothctl pair D6:A3:C1:F9:2C:21 Attempting to pair with D6:A3:C1:F9:2C:21 [CHG] Device D6:A3:C1:F9:2C:21 Paired: yes Pairing successful
