Bose SoundTouch API Client

A modern Go library and CLI tool for interacting with Bose SoundTouch devices via their Web API.

Features

✅ Implemented (Phase 1)

• HTTP Client with XML Support: Complete client for SoundTouch Web API
• Device Information: Get detailed device info via /info endpoint
• UPnP Discovery: Automatic device discovery on local network
• Cross-Platform: Works on Windows, macOS, Linux, and WASM
• CLI Tool: Command-line interface for testing and basic operations
• Comprehensive Tests: Unit and integration tests with real device responses
• Flexible Configuration: Support for .env files and environment variables
• Hybrid Discovery: Combines UPnP discovery with configured device lists

🔄 Planned

• Real-time WebSocket events
• Playback control (play, pause, volume, etc.)
• Source management (Spotify, Bluetooth, etc.)
• Preset management
• Web application interface
• Multi-room zone support

Installation

Using Go

go install github.com/user_account/bose-soundtouch/cmd/soundtouch-cli@latest

From Source

git clone https://github.com/user_account/bose-soundtouch.git
cd bose-soundtouch
make build

Quick Start

Configuration

Create a .env file in your working directory to configure preferred devices:

# Copy the example file
cp .env.example .env

Example .env configuration:

# Discovery Settings
DISCOVERY_TIMEOUT=5s
UPNP_ENABLED=true

# Preferred Devices (alternative to UPnP)
# Format: name@host:port;name@host:port;...
PREFERRED_DEVICES="Living Room@192.168.1.100;Kitchen@192.168.1.101;192.168.1.102:8091"

# HTTP Client Settings
HTTP_TIMEOUT=10s
USER_AGENT="Bose-SoundTouch-Go-Client/1.0"

CLI Usage

Device Discovery

# Discover SoundTouch devices (combines UPnP + configured devices)
soundtouch-cli -discover

# Discover and show detailed info for all devices
soundtouch-cli -discover-all

Device Information

# Get device information by IP address
soundtouch-cli -host 192.168.1.100 -info

# With custom port and timeout
soundtouch-cli -host 192.168.1.100 -port 8090 -timeout 15s -info

Go Library Usage

package main

import (
    "context"
    "fmt"
    "log"
    "time"

    "github.com/user_account/bose-soundtouch/pkg/client"
    "github.com/user_account/bose-soundtouch/pkg/discovery"
)

func main() {
    // Option 1: Connect to known device
    soundtouchClient := client.NewClientFromHost("192.168.1.100")
    
    deviceInfo, err := soundtouchClient.GetDeviceInfo()
    if err != nil {
        log.Fatal(err)
    }
    
    fmt.Printf("Device: %s (%s)\n", deviceInfo.Name, deviceInfo.Type)

    // Option 2: Discover devices automatically
    discoveryService := discovery.NewDiscoveryService(5 * time.Second)
    ctx := context.Background()
    
    devices, err := discoveryService.DiscoverDevices(ctx)
    if err != nil {
        log.Fatal(err)
    }
    
    for _, device := range devices {
        fmt.Printf("Found: %s at %s:%d\n", device.Name, device.Host, device.Port)
    }
}

API Documentation

The SoundTouch Web API uses HTTP with XML payloads. Key endpoints include:

• GET /info - Device information
• GET /now_playing - Current playback status
• POST /key - Send key commands (play, pause, etc.)
• GET/POST /volume - Volume control
• GET /sources - Available audio sources
• WebSocket / - Real-time event stream

For complete API documentation, see docs/API-Endpoints-Overview.md.

Configuration Options

The application supports configuration through .env files and environment variables:

Variable	Default	Description
DISCOVERY_TIMEOUT	5s	Timeout for device discovery
UPNP_ENABLED	true	Enable/disable UPnP discovery
PREFERRED_DEVICES	(empty)	Semicolon-separated list of devices
HTTP_TIMEOUT	10s	HTTP client timeout
CACHE_ENABLED	true	Enable device caching
CACHE_TTL	30s	Cache time-to-live

Device Configuration Format

The PREFERRED_DEVICES environment variable supports multiple formats:

# Host only (uses default port 8090)
PREFERRED_DEVICES="192.168.1.100"

# Host with port
PREFERRED_DEVICES="192.168.1.100:8091"

# Named device
PREFERRED_DEVICES="Living Room@192.168.1.100"

# Multiple devices
PREFERRED_DEVICES="Living Room@192.168.1.100;Kitchen@192.168.1.101:8091"

Supported Devices

Tested with:

• Bose SoundTouch 10
• Bose SoundTouch 20

Should work with all SoundTouch series devices that support the Web API.

Architecture

This project follows modern Go patterns:

• Clean Architecture: Separated concerns with pkg structure
• Interface-Based Design: Testable and mockable components
• Cross-Platform: Supports Windows, macOS, Linux, and WASM
• Test-Driven: Comprehensive unit and integration tests
• Real Device Integration: Tested with actual SoundTouch hardware

Contributing

1. Fork the repository
2. Create a feature branch
3. Add tests for new functionality
4. Ensure all tests pass: make check
5. Submit a pull request

Development Guidelines

• Tests are mandatory: Every feature needs corresponding tests
• KISS principle: Keep implementations simple and readable
• Small iterations: Break large features into testable chunks
• Real device testing: Validate against actual SoundTouch devices
• Cross-platform compatibility: Test on multiple platforms
