根据您提供的信息,我可以看到设备返回的UUID列表。其中,包含了读取和写入Characteristic值的UUID。要设置所有TXRX,您需要使用AT指令向设备写入相应的UUID。根据收到的响应,您需要向以下UUID写入相应的值:
- 读取UUID: 2A00, 2A01, 2A04, 2AA6, 2A23, 2A24, 2A25, 2A26, 2A27, 2A28, 2A29, 2A2A, 2A50
- 写入UUID: 43484152-2DAB-3141-6972-6F6861424C45, EA2021FF-0000-1000-1000-000000FFFF00, EA2021FF-0000-1000-1000-000000FE0200, EA2021FF-0000-1000-1000-000000FEFF00
您可以使用AT+CHRX和AT+CHTX命令分别设置读取和写入UUID。例如,要设置读取UUID 2A00,您可以使用以下命令:
```
AT+CHRX=2A00
```
要设置写入UUID EA2021FF-0000-1000-1000-000000FEFF00,您可以使用以下命令:
```
AT+CHTX=EA2021FF-0000-1000-1000-000000FEFF00
```
请注意,您需要根据您的设备和通信协议来确定正确的UUID。根据您提供的信息,设备返回的UUID可能不完整。如果您需要更多帮助,请向设备制造商或通信协议文档提供者咨询。

jdbc:oracle:thin:@//10.39.192.10:1521/jzgzgl 怎么连接数据库
您可以使用以下代码连接到Oracle数据库:
```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class OracleConnection {
public static void main(String[] args) {
// JDBC driver name and database URL
String jdbcDriver = "oracle.jdbc.driver.OracleDriver";
String dbUrl = "jdbc:oracle:thin:@//10.39.192.10:1521/jzgzgl";
// Database credentials
String user = "your_username";
String password = "your_password";
Connection conn = null;
try {
// Register the JDBC driver
Class.forName(jdbcDriver);
// Open a connection
conn = DriverManager.getConnection(dbUrl, user, password);
// Do something with the connection
// ...
// Close the connection
conn.close();
} catch (SQLException se) {
// Handle errors for JDBC
se.printStackTrace();
} catch (Exception e) {
// Handle errors for Class.forName
e.printStackTrace();
} finally {
// Close resources
try {
if (conn != null) conn.close();
} catch (SQLException se) {
se.printStackTrace();
}
}
}
}
```
请替换 `your_username` 和 `your_password` 为您的Oracle数据库的用户名和密码。
java.security.KeyManagementException: org.apache.http.conn.HttpHostConnectException
java.security.KeyManagementException: org.apache.http.conn.HttpHostConnectException是一个Java异常,表示在使用HttpClient发送请求时发生了连接异常。具体来说,这个异常通常是由于无法连接到指定的主机或端口引起的。
以下是一个示例代码,演示了如何使用HttpClient发送请求并处理连接异常:
```java
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.conn.HttpHostConnectException;
public class HttpClientExample {
public static void main(String[] args) {
HttpClient httpClient = HttpClientBuilder.create().build();
HttpGet request = new HttpGet("http://example.com");
try {
httpClient.execute(request);
} catch (HttpHostConnectException e) {
// 处理连接异常
e.printStackTrace();
} catch (Exception e) {
// 处理其他异常
e.printStackTrace();
}
}
}
```
在上面的代码中,我们创建了一个HttpClient对象,并使用HttpGet请求发送到"http://example.com"。如果无法连接到该主机或端口,就会抛出HttpHostConnectException异常。我们可以在catch块中处理这个异常,例如打印异常信息或执行其他操作。
