Hello,
IoT devices are taking over the world by
being always connected and extremely functional to serve as a solution for
variety of technical requirements. I’ve been experimenting with them for a couple
of months and found them technically intriguing and worth great value. However,
if you’re experimenting with an IoT device or wish to communicate with the same
using a regular desktop-pc or laptop running any modern OS, there will be a
need to communicate with the device after deployment to debug issues or collect
sensors data.
This communication with the IoT
Device usually happens through the famous and extremely versatile Universal
Serial Bus (USB) communication protocol found in modern electronics hardware.
In order to use an IoT device to communicate with a pc, one can simply connect
the same via regular UART/USB interface cable and use following code (written
in C#) to communicate with the device:
Code Snippet:
[DllImport("user32.dll")] //Required for
the Serial Communication
static void Main(string[] args)
{
Initialize();
}
private static void Initialize()
{
SerialPort mySerialPort = new SerialPort("COM3"); //Port
Selection
mySerialPort.BaudRate = 115200; //Set as per
setting on Device
mySerialPort.Parity = Parity.None;
mySerialPort.StopBits = StopBits.One;
mySerialPort.DataBits = 8;
mySerialPort.Handshake = Handshake.None;
mySerialPort.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);
mySerialPort.Open();
Console.WriteLine("Awaiting
for the data...");
Console.ReadKey();
mySerialPort.Close();
}
private static void DataReceivedHandler(object
sender, SerialDataReceivedEventArgs e)
{
try
{
SerialPort sp = (SerialPort)sender;
string indata = sp.ReadLine();
Console.WriteLine(indata); //Print received information
}
catch (Exception
ex)
{
Console.WriteLine(ex.Message.ToString());
}
}
