# @ohos.bluetooth.map (Bluetooth MAP Module)

The **bluetooth.map** module provides APIs for exchanging messages between devices.

> **NOTE**
>
> The initial APIs of this module are supported since API version 11. Newly added APIs will be marked with a superscript to indicate their earliest API version.



## Modules to Import

```js
import map from '@ohos.bluetooth.map';
```


## map.createMapMseProfile

createMapMseProfile(): MapMseProfile

Creates a **MapMseProfile** instance.

**System capability**: SystemCapability.Communication.Bluetooth.Core

**Return value**

| Type                           | Description        |
| ----------------------------- | ---------- |
| MapMseProfile | **MapMseProfile** instance created.|

**Example**

```js
import { BusinessError } from '@ohos.base';
try {
    let mapMseProfile = map.createMapMseProfile();
    console.info('MapMse success');
} catch (err) {
    console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
}
```


## mapMseProfile

Provides APIs for exchanging messages between devices using the Bluetooth Message Access Profile (MAP). Before using any API of **mapMseProfile**, you need to create an instance of this class by using **createMapMseProfile()**.
