HarmonyOS 打开蓝牙，报201 Permission denied.？

Question

调用以下代码打开蓝牙，报 201 Permission denied.

import { access } from '@kit.ConnectivityKit';
import { AsyncCallback, BusinessError } from '@kit.BasicServicesKit';
try {
  access.enableBluetooth();
} catch (err) {
  console.error('errCode: ' + (err as BusinessError).code + ', errMessage: ' + (err as BusinessError).message);
}

权限已开启

{
  // 蓝牙
  "name": "ohos.permission.ACCESS_BLUETOOTH",
"reason": "$string:app_name",
"usedScene": {
  "when":"inuse"
}
},

Answer 1

module.json5文件内:

"requestPermissions": [
{
  "name": "ohos.permission.ACCESS_BLUETOOTH",
"reason": "$string:EntryAbility_desc",
"usedScene": {
  "abilities": [
  "EntryAbility"
  ],
  "when": "always"
}
}
]

ACCESS.BLUETOOTH权限需要为用户授权才可使用，用户授权demo可参考：

let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
try {
  let context = getContext(this);
  atManager.requestPermissionsFromUser(context, [‘ohos.permission.ACCESS_BLUETOOTH’], (err: BusinessError, data: PermissionRequestResult)=>{
    console.info(‘data:’ + JSON.stringify(data));
    console.info(‘data permissions:’ + data.permissions);
    console.info(‘data authResults:’ + data.authResults);
  });
} catch(err) {
  console.log(catch err->${JSON.stringify(err)});
}
