# registerForConnectionEvents(options:)

Register for an event notification when the central manager makes a connection matching the given options.

```
func registerForConnectionEvents(options: [CBConnectionEventMatchingOption : Any]? = nil)
```

## Parameters

`options`

A dictionary that specifies options for connection events. See [Peripheral Connection Options](/documentation/CoreBluetooth/peripheral-connection-options) for a list of possible options.

## Discussion

When the central manager makes a connection that matches the options, it calls the delegate’s [`centralManager(_:connectionEventDidOccur:for:)`](/documentation/CoreBluetooth/CBCentralManagerDelegate/centralManager(_:connectionEventDidOccur:for:)) method.
