# Bluetooth Subsystem Changelog

## cl.bluetooth.1 Split of Bluetooth APIs by Profile

1. Split ArkTS APIs in corresponding .d.ts files.
2. Changed the interface permission to **ohos.permission.ACCESS_BLUETOOTH**. [Some APIs](#apis-requiring-dual-permission-verification) also require the **ohos.permission.MANAGE_BLUETOOTH** permission.

**Change Impact**

1. The module to import is changed.
2. After the permission change, you only need to pay attention to the **ohos.permission.ACCESS_BLUETOOTH** and **ohos.permission.MANAGE_BLUETOOTH** permissions.

**Adaptation Guide**

Determine the module to import based on the profile module. For some interfaces, multiple TS files need to be imported.

```js
//For example, getConnectionState() in @ohos.bluetooth.baseProfile.
import a2dp from '@ohos.bluetooth.a2dp';
try {
    let a2dpSrc = a2dp.createA2dpSrcProfile();
    let ret = a2dpSrc.getConnectionState('XX:XX:XX:XX:XX:XX');
} catch (err) {
    console.error('errCode: ' + err.code + ', errMessage: ' + err.message);
}

```
