AEP service class IDs

  • Article

Association Endpoint (AEP) services provide a programming contract for services that a device supports over a given protocol. Several of these services have established identifiers that should be used when referencing them. These contracts are identified with the System.Devices.AepService.ServiceClassId property. This topic lists several well-known AEP service class IDs. The AEP service class ID is also applicable to protocols with custom class IDs.

An app developer should use Advanced Query Syntax (AQS) filters based on the class IDs to limit their queries to the AEP services they plan to use. This will both limit the query results to the relevant services and will significantly increase the performance, battery life, and quality of service for the device. For example, an application can use these service class IDs to use a device as a Miracast sync or DLNA digital media renderer (DMR). For more information about how devices and services interact with each other, see DeviceInformationKind.

Bluetooth and Bluetooth LE services

Bluetooth services fall under one of two protocols, either the Bluetooth protocol or the Bluetooth LE protocol. The identifiers for these protocols are:

  • Bluetooth protocol ID: {e0cbf06c-cd8b-4647-bb8a-263b43f0f974}
  • Bluetooth LE protocol ID: {bb7bb05e-5972-42b5-94fc-76eaa7084d49}

The Bluetooth protocol supports several services, all following the same basic format. The first group of digits in the GUID vary based upon the service, but all Bluetooth GUIDs end with -0000-1000-8000-00805F9B34FB. For example, the RFCOMM service has the precursor of 0x0003, so the full ID would be 00000003-0000-1000-8000-00805F9B34FB. The following table lists some common Bluetooth services.
