BondManager

Manages Bluetooth device bonding (pairing) operations.

Bonding is the process of establishing a trusted relationship between two Bluetooth devices. Once bonded, devices can automatically reconnect and communicate securely without requiring user interaction for each connection.

This class provides a reactive approach to bonding using Kotlin coroutines Flow, allowing callers to observe bond state changes in real-time.

Bond States

• BondState.BOND_NONE - No bond exists; devices are not paired

• BondState.BOND_BONDING - Bonding is in progress; user may need to confirm pairing

• BondState.BOND_BONDED - Devices are successfully bonded/paired

Usage Example

val bondManager = BondManager(context)

bondManager.bondDevice(bluetoothDevice)
    .collect { bondState ->
        when (bondState) {
            BondState.BOND_BONDING -> showPairingDialog()
            BondState.BOND_BONDED -> onPairingSuccessful()
            BondState.BOND_NONE -> onPairingFailed()
        }
    }

Permissions

Requires android.Manifest.permission.BLUETOOTH_CONNECT on Android 12 (API 31) and above.
