Smdn.Net.SkStackIP 1.2.0

Smdn.Net.SkStackIP 1.2.0

Smdn.Net.SkStackIP is a library that provides APIs for operating devices that implement Skyley Networks' SKSTACK IP.

This library supports to use any Stream or PipeReader/PipeWriter as the communication channel for the SKSTACK IP protocol, so it has the ability to communicate with devices that use other than serial ports, e.g., pseudo devices.

Getting started

First, add package Smdn.Net.SkStackIP and System.IO.Ports to the project file.

dotnet add package Smdn.Net.SkStackIP
dotnet add package System.IO.Ports

Next, open the serial port to which the SKSTACK-IP device is connected using with the SerialPort class.

Then, create a SkStackClient instance from the SerialPort.BaseStream and call the SkStackClient's method to send the command.

using Smdn.Net.SkStackIP;

// Open the serial port to which the device implementing SKSTACK-IP is connected
using var port = new SerialPort(
  portName: "/dev/ttyACM0", // Specify a port name such as COM1 on Windows
  baudRate: 115200, // Specify the appropriate baud rate for the device
  parity: Parity.None,
  dataBits: 8,
  stopBits: StopBits.One
) {
  Handshake = Handshake.None,
  DtrEnable = false,
  RtsEnable = false,
  NewLine = "/r/n", // CRLF
};

port.Open();
port.DiscardInBuffer(); // Discard previous buffer contents before communication starts.

// Create a SkStackClient instance based on a stream of the SerialPort instance
using var client = new SkStackClient(stream: port.BaseStream);

// Send SKVER command to get and display the firmware version of SKSTACK IP
var respSKVER = await client.SendSKVERAsync();

Console.WriteLine($"VER: {respSKVER.Payload}");

// Send SKAPPVER command to get and display the firmware version of application
var respSKAPPVER = await client.SendSKAPPVERAsync();

Console.WriteLine($"APPVER: {respSKAPPVER.Payload}");

// Send SKINFO command to get and display the communication configurations.
var respSKINFO = await client.SendSKINFOAsync();

Console.WriteLine($"LinkLocalAddress: {respSKINFO.Payload.LinkLocalAddress}");
Console.WriteLine($"MacAddress: {respSKINFO.Payload.MacAddress}");
Console.WriteLine($"Channel: {respSKINFO.Payload.Channel}");
Console.WriteLine($"PanId: {respSKINFO.Payload.PanId:X4}");
