21.1 | 87 | Write to the UDP port that the device node sends to the server |
| |

| |
21.1 | 89 | Example My UDP device node sends to server port 8585 |
| 90 | just write 8585 | ||
| |
20.2 | 91 | |
| |
21.1 | 92 | Note that the port that is already in use cannot be used. If the receiving fails, you need to check whether the port of the server is occupied. The sending port of the device node should not use the default port used by the server, such as a common port such as 8080. |
| |
20.2 | 93 | |
| |
21.1 | 94 | In order to avoid data confusion, different types of nodes do not use the same UDP port, because different nodes have different data formats and different functions. |
