HarmonyOS 鸿蒙Next 权限级别不够，怎么签名
权限级别不够，怎么签名 我需要使用BLE蓝牙，但是需要ohos.permission.MANAGE_BLUETOOTH这个权限
我在requestPermissions配置了，但是又需要我签名，我想问一下这个需要怎么签名?

签名分为自动签名跟手动签名， 参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V13/ide-signing-V13#section18815157237
自动化签名的调试方式要求您的网络可以访问Internet。如果您的应用/元服务调试时无法联网，可以在AGC中申请调试证书和Profile后，再通过手动签名的方式进行调试，具体步骤请参见手动签名方式调试HarmonyOS应用/元服务。

1.是这样一个流程，AppGallery Connect地址：https://developer.huawei.com/consumer/cn/service/josp/agc/index.html

2.ohos.permission.MANAGE_BLUETOOTH权限设置:https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V13/app-permissions-V13
试下能否解决问题
现在这个权限是系统权限，暂不支持第三方使用。

return;
}

// 授权成功
