Raw bluetooth for Go

This is a raw bluetooth library which connects to a MAC address by using syscall on Linux and Windows.

Features

• Implements a simple Read/Write interface.
• Same behavior on Linux and Windows.
• Zero-dependency (expect Go's x/sys)
• Built-in scanner for devices
  • Linux: using the hcitool
  • Windows: no dependency (WSALookupService)

Roadmap

• Rewrite Linux scan not to use hcitool
• Add Darwin supports to Communicator

Usage

package main

import (
	"fmt"

	"github.com/infiniteloopcloud/bluetooth-go"
)

func main() {
	// Connect
	conn, err := bluetooth.Connect(bluetooth.Params{
		Address: "58:CF:0A:BB:28:FC",
	})
	if err != nil {
		// handle err
	}

	// Write data into the connection
	_, err = conn.Write([]byte("data"))
	if err != nil {
		// handle err
	}

	// Read from connection
	_, data, err := conn.Read(500)
	if err != nil {
		// handle err
	}
	fmt.Println(string(data))
	
	// Close connection
	err = conn.Close()
	if err != nil {
		// handle err
	}
}

Implement custom logger

package main

import (
	"fmt"

	"github.com/infiniteloopcloud/bluetooth-go"
)

type Logger struct{}

func (Logger) Print(a ...interface{}) {
	fmt.Println(a...)
}

func main() {
	// Connect
	_, err := bluetooth.Connect(bluetooth.Params{
		Address: "58:CF:0A:BB:28:FC",
		Log: Logger{},
	})
	if err != nil {
		// handle err
	}
	//....
}

Scanner

package main

import (
	"fmt"

	"github.com/infiniteloopcloud/bluetooth-go"
)

func main() {
	devices, err := bluetooth.NewScanner().Scan()
	if err != nil {
		// handle err
	}
	fmt.Println(devices)
}
