📋 Prerequisites

Before you begin, ensure you have:

• Development Environment:

  • macOS Monterey (12.0) or later
  • Xcode 15.0 or later
  • iOS device running iOS 17.0+ (not simulator - requires Bluetooth)

• Hardware:

  • Meta Ray-Ban smart glasses (Wayfarer or other models)
  • OR use iPhone camera for testing (fallback mode)

• Accounts & API Keys:

  • Anthropic API key (Claude)
  • Meta AI app installed on your iPhone
  • Developer Mode enabled in Meta AI app (free)

🚀 Installation

1. Clone the Repository

git clone https://github.com/yourusername/jarvis.git
cd jarvis

2. Install Dependencies

This project uses Swift Package Manager. Dependencies will be resolved automatically when you open the project in Xcode.

Required packages:

• Meta Wearables DAT SDK (v0.4.0)

3. Open in Xcode

open Jarvis/Jarvis.xcodeproj

4. Configure Constants

The project includes a template configuration file:

# The Constants.swift file is gitignored and will be empty by default
# This is intentional - API keys are managed in-app!

Note: You do NOT need to add your API key to any config file. The app handles API key management securely through its Settings interface.

5. Configure Code Signing

1. In Xcode, select the Jarvis target
2. Go to Signing & Capabilities
3. Select your Development Team
4. Xcode will automatically manage provisioning profiles

6. Build and Run

1. Connect your iPhone via USB
2. Select your device in Xcode
3. Press Cmd+R to build and run

⚙️ Configuration

First Launch Setup

When you first launch Jarvis, you'll be guided through a setup process:

1. API Key Setup

• The app will show an "API Key Required" screen
• Tap Setup
• Enter your Anthropic API key (starts with sk-ant-)
• Get your key from: console.anthropic.com
• The key is stored securely in iOS Keychain

2. Meta Glasses Connection (Developer Mode)

Enable Developer Mode:

1. Install the Meta AI app from the App Store
2. Pair your Meta Ray-Ban glasses with the Meta AI app
3. In Meta AI app: Settings → Devices → [Your Glasses] → Developer Mode
4. Enable Developer Mode (free, no registration required)

Connect Glasses to Jarvis:

1. Open Jarvis app
2. Ensure Bluetooth is enabled on iPhone
3. Tap Start Session when glasses are detected
4. Grant camera and microphone permissions when prompted

3. Permissions

Jarvis requires the following permissions:

• Bluetooth - To connect to Meta Ray-Ban glasses
• Microphone - For voice conversations with Claude
• Camera - For iPhone fallback mode (optional)
• Photos - To save captured photos (optional)

Advanced Configuration

Custom Settings

Edit Jarvis/Jarvis/Config/Constants.swift for advanced options:

// Video quality (adjust for performance)
enum Video {
    static let streamingFPS: Int = 30        // Max from glasses
    static let llmThrottleFPS: Double = 1.5  // Sent to Claude
    static let jpegQuality: CGFloat = 0.5    // Compression (0.0-1.0)
}

// Feature flags
enum Features {
    static let enableIPhoneFallback: Bool = true
    static let enablePhotoCapture: Bool = true
}

Managing API Keys

View/Change API Key:

🔧 Troubleshooting

Common Issues

"Device Disconnected" Status

Causes:

• Glasses are powered off
• Glasses hinges are closed (they auto-sleep)
• Bluetooth disabled on iPhone
• Glasses not in Developer Mode

Solutions:

1. Open glasses hinges fully
2. Check Bluetooth is enabled
3. Verify Developer Mode in Meta AI app
4. Try unpairing and re-pairing in Meta AI app

"API Key Required" Status

Solution:

1. Tap API Key tile
2. Enter your Anthropic API key
3. Get key from console.anthropic.com

Video Stream Laggy

Solutions:

1. Close other Bluetooth-heavy apps
2. Reduce Video.jpegQuality in Constants.swift
3. Lower Video.llmThrottleFPS if needed
4. Ensure strong Bluetooth connection (keep glasses close to phone)

No Audio Response

Causes:

• Invalid API key
• Microphone permission denied
• Speaker volume too low

Solutions:

1. Verify API key in Settings
2. Check microphone permission: Settings → Jarvis → Microphone
3. Increase volume
4. Try toggling between glasses/iPhone audio modes

App Crashes on Launch

Solutions:

1. Clean build folder: Cmd+Shift+K
2. Delete derived data: Xcode → Preferences → Locations → Derived Data
3. Reinstall app on device
4. Check Console app for crash logs

Performance Optimization

If experiencing lag or high battery drain:

// In Constants.swift, reduce these values:
enum Video {
    static let llmThrottleFPS: Double = 1.0  // From 1.5
    static let jpegQuality: CGFloat = 0.3    // From 0.5
}

💰 Cost Estimation

Claude API Pricing:

• Vision API: ~$0.003 per image (1-2 FPS = $0.18-$0.36 per 10-min session)
• Text generation: ~$0.003 per 1K tokens
• Estimated: $0.50-$1.00 per hour of active use

Tips to reduce costs:

• Lower llmThrottleFPS to send fewer images
• Use shorter sessions
• Monitor usage in Anthropic Console

⚠️ Important Notes

• Privacy: All conversations are stored locally on your device. Enable iCloud sync cautiously.
• Battery: Continuous video streaming drains battery faster. Consider bringing a portable charger.
• Data Usage: Streaming video to Claude uses data. Use Wi-Fi when possible or monitor cellular usage.
• Developer Mode: Meta's Developer Mode is free but may have usage limits. Check Meta's documentation.
