108 -just write 8585

110 -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.
111 -
112 -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.
