Overloads
| DiscoverCharacteristics(CBService) |
Discover all characteristics in a service (slow). |
| DiscoverCharacteristics(CBUUID[], CBService) |
Discovers the list of characteristics in the specified service. |
DiscoverCharacteristics(CBService)
Discover all characteristics in a service (slow).
public void DiscoverCharacteristics (CoreBluetooth.CBService forService);member this.DiscoverCharacteristics : CoreBluetooth.CBService -> unitParameters
- forService
- CBService
Service that you want to discover all the characteristics for.
Remarks
When the characteristics are discovered, the event DiscoverCharacteristic is raised (or alternatively, if you set a Delegate, the method DiscoverCharacteristic on the delegate is invoked with the results).
Once the characterstics have been discovered, they are available on the Characteristics property.
This method is potentially slow and will return all the characteristics supported by the service. Ideally, you should use the overload that allows you to specifify an array of CBUUIDs as that will be faster.
