go-span-client

This repository contains a simple client library for communicating with Span as an IoT device. If you want to access the Span API for managing Span resources, the library you want is the Go Span API Client.

This library uses the Pion DTLS library.

Minimal example

package main

import (
    "log"
    "time"
    client "github.com/borud/go-span-client"
)

func main() {
    client, err := client.Connect(client.NewDefaultConfig())
    if err != nil {
        log.Fatal(err)
    }
    defer client.Close()
   
    n, err := client.Write([]byte("this is a test"), time.Second)
    if err != nil {
        log.Fatal(err)
    }
    log.Printf("wrote %d bytes", n)
   
    buffer := make([]byte, 1024)
   
    n, err = client.Read(buffer, time.Second*5)
    if err != nil {
        log.Fatal(err)
    }
    log.Printf("read %d bytes: [%s]", n, string(buffer))
}
