+# @ohos.bluetooth.hfp (Bluetooth hfp Module)
+
+The **hfp** module provides APIs for using the Bluetooth Hands-Free Profile (HFP).
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+
+
+## Modules to Import
+
+```js
+import hfp from '@ohos.bluetooth.hfp';
+```
+
+
+## hfp.createHfpAgProfile<a name="createHfpAgProfile"></a>
+
+createHfpAgProfile(): HandsFreeAudioGatewayProfile
+
+Creates an **HfpAgProfile** instance.
+
+**System capability**: SystemCapability.Communication.Bluetooth.Core
