Iotp2pgate two IOT devices point-to-point communication fast implementation scheme

IoTP2PGate

Project address

IoTP2PGate

describe

   In order to solve the problem that the communication module of the Internet of things cannot quickly realize point-to-point communication with mobile phones or other Internet of things devices ,IoTP2PGate emerge as the times require .IoTP2PGate It is mainly used for simple development verification , After all, it was written for the convenience of graduation design .

characteristic

1. It supports and only supports point-to-point communication between two IOT devices .
2. The device will (ip,port) As the address of another device , Hide the server forwarding process behind .

Use

1. Prepare to have a public network IP,Linux One ECS of the system .( Please ensure that the firewall on the server and the firewall provided by the cloud service provider platform have opened the corresponding ports )
2. Enter the following command to download and compile IoTP2PGate ：

git clone https://github.com/MisakaMikoto128/IoTP2PGate.git
cd IoTP2PGate
make

perhaps

git clone https://gitee.com/liuyuanlin6445/IoTP2PGate.git
cd IoTP2PGate
make

3. Use ：

./p2pgate <port> [debug]

• debug Is an optional parameter , Used to view information in the communication process .
• port Is the port number , Mandatory . for example 666
• eg: ./p2pgate 666

4. At this time, two network connected devices pass socket.connect( Server public network IP,PORT) To establish its TCP Connect , The two devices can communicate with each other .

matters needing attention

1. Two socket After the connection between the client and the server is established, the channel for mutual communication is officially established .
2. after IoTP2PGate Will reject other sockt Connect until the original two socket One or all of the clients disconnect from the server .
