Bluetooth LE supports the ability to send authenticated data over an unencrypted ATT bearer between two devices with a trusted relationship. This is accomplished by signing the data with a Connection Signature Resolving Key (CSRK). The sending device places a signature after the Data PDU. The receiving device verifies the signature and if the signature is verified the Data

PDU is accepted as authentic.
蓝牙低功耗支持在两个具有信任关系的设备之间通过未加密的ATT承载发送经过身份验证的数据。这是通过使用连接签名解析密钥(CSRK)对数据进行签名来实现的。发送设备在数据PDU之后放置签名。接收设备验证签名,如果签名验证成功,则接受数据PDU为真实的。

Gradle JVM version incompatible. This project is configured to use an older Gradle JVM that supports up to version 11 but the current AGP requires a Gradle JVM that supports version 17.
这个问题是因为你的 Android Gradle 插件需要使用支持到 Java 17 版本的 Gradle JVM,而你当前使用的 Gradle JVM 版本只支持到 Java 11。解决这个问题需要升级你的 Gradle JVM 版本,具体步骤如下:
1. 打开你的项目根目录下的 gradle/wrapper/gradle-wrapper.properties 文件。
2. 修改 distributionUrl 属性的值为最新版本的 Gradle,例如:
```
distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip
```
这里以 Gradle 7.3.3 版本为例。
3. 保存修改后的 gradle-wrapper.properties 文件。
4. 在 Android Studio 中点击菜单栏的 "File" -> "Invalidate Caches / Restart",然后选择 "Invalidate and Restart" 选项重启 Android Studio。
5. 等待 Android Studio 重新构建 Gradle 项目,这可能需要一些时间。
6. 如果一切顺利,你的项目现在应该能够正常运行了。如果还有其他问题,请检查你的项目配置是否正确,或者在 Stack Overflow 等社区寻求帮助。
urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'OpenSSL 1.1.0h 27 Mar 2018'.
I see that you are facing an issue with urllib3 version 2.0. It requires OpenSSL 1.1.1, but currently, your 'ssl' module is compiled with OpenSSL 1.1.0h from March 27, 2018. To resolve this issue, you have a few options:
1. Upgrade OpenSSL: You can try upgrading your OpenSSL version to 1.1.1 or above. You may need to consult the documentation or support resources of your operating system or package manager for instructions on how to do this.
2. Use a different urllib3 version: If upgrading OpenSSL is not feasible, you can try using a different version of urllib3 that is compatible with your current OpenSSL version. You can check the urllib3 documentation or project page for more information on compatible versions.
3. Downgrade OpenSSL: Another option is to downgrade your OpenSSL version to 1.1.0h or an earlier version that is compatible with urllib3 v2.0. Again, you may need to refer to the documentation or support resources for your operating system or package manager for instructions on how to do this.
Remember to carefully consider the security implications of upgrading or downgrading your OpenSSL version and make sure it aligns with your specific requirements.
