### IOBOX API USAGE GUIDE
   This document provides an overview and usage instructions for the APIs available in `iobox_api.h`.
#### 1. Api name and features
* Scan

    `std::vector<std::string> scanNetworkDevicesMulticast(int timeout);`
    
    API need to be passed a timeout in second unit. The API will return a list of IPs as a vector string.
* Connect

    `bool connectToIobox(const std::string& ip, int port); `
    
    Connect to a specific IP device from list of IPs above. Default port is 502.

* Disconnect

    `bool disconnectToIobox(const std::string& ip);`

    Disconnect to a specific IP device that is connected before

* Get value of channel

    `std::string getValueDataStringIoboxFromChannelName(const std::string& ip, const std::string& channelName);`

    Get value of specific channel name from a IP device that is connected before. 
    List of channel name is included in `channel_name` array.

* Set value of channel

    `bool setValueDataStringIoboxFromChannelName(const std::string& ip, const std::string& channelName, const std::string& value);`

    Set a value of specific channel name from a IP device that is connected before. List of channel name is included in `channel_name` array.

#### 2. How to using example test in main.cpp

You need build this project before run by using g++ compiler

`g++ .\*.cpp -lws2_32 -o main.exe`

Then you need only running `main.exe`.

Start application, it will show

`Enter command followed by Enter: exit, scan, setip, connect, disconnect, show, get, set`

* You type `scan`, it will scan all device iobox on local network then it will list them on terminal attach their IP address if they is found.
* Then type `setip` to setup IP of iobox you need to connect
    Then you will be required to input of specific IP address and you need type IP you want.
* Next you type  `connect` to connect to this IP device
* Then you can use `get` or `set` command to continue get or set value to any channel.
