SMS Campaign Manager 📱

Dockerized SMS automation system with Android integration

🚀 Quick Start

One-Command Deployment

# 1. Deploy to Android with correct directory structure
# Scripts go to ~/bin/
scp -P 8022 android/*.sh android-dev@10.0.0.193:~/bin/
ssh android-dev "chmod +x ~/bin/*.sh"

# Python apps go to ~/projects/sms-campaign-manager/
ssh android-dev "mkdir -p ~/projects/sms-campaign-manager"
scp -P 8022 android/*.py android-dev@10.0.0.193:~/projects/sms-campaign-manager/

# Start all services
ssh android-dev "~/bin/start-all-services.sh"

# 2. Start Ubuntu homelab
./run.sh start
# OR with docker-compose
docker-compose up -d

# 3. Verify everything is running
curl http://10.0.0.193:5001/health    # Android SMS API
curl http://10.0.0.193:5000/          # Android Monitor  
curl http://localhost:5000/           # Ubuntu Dashboard

Prerequisites

• Docker & Docker Compose installed
• Android device with USB debugging enabled
• Local network access to Android device

1. Clone and Configure

# Clone or navigate to project directory
cd "ABD Texting Testing"

# Copy environment template
cp config/.env.example .env

# Edit configuration for your Android device
nano .env

2. Launch with Docker Compose

# Quick start using convenience script
./run.sh start

# Or manually with docker-compose
docker-compose up -d

# View logs
docker-compose logs -f

# Access web interface
open http://localhost:5000

3. Connect Your Android Device

The system will automatically discover and connect to your Android device using the IP configured in .env.

4. Deploy Android Services

Copy the pre-configured service files to their correct directories on Termux:

# Deploy shell scripts to ~/bin/ directory
scp -P 8022 android/*.sh android-dev@10.0.0.193:~/bin/
ssh -p 8022 android-dev@10.0.0.193 "chmod +x ~/bin/*.sh"

# Deploy Python applications to ~/projects/sms-campaign-manager/
ssh -p 8022 android-dev@10.0.0.193 "mkdir -p ~/projects/sms-campaign-manager"
scp -P 8022 android/app.py android/termux-sms-api-server.py android-dev@10.0.0.193:~/projects/sms-campaign-manager/

# Verify deployment
ssh android-dev "ls -la ~/bin/*.sh && ls -la ~/projects/sms-campaign-manager/*.py"

5. Start Android Services

Your S24 Ultra runs two services for SMS operations. Use the automated startup script:

# Start all services at once (recommended)
ssh android-dev "~/bin/start-all-services.sh"

# Or start services individually:
ssh android-dev "~/bin/sms-service.sh start"        # SMS API Server
ssh android-dev "~/bin/start-monitoring.sh"         # Monitoring Interface

# Check service status
ssh android-dev "~/bin/sms-service.sh status"
curl http://10.0.0.193:5001/health                  # SMS API health check
curl http://10.0.0.193:5000/                        # Monitoring dashboard

Available Service Scripts:

• start-all-services.sh - Start both services with health checks
• sms-service.sh - Service management (start/stop/status)
• start-sms-api.sh - SMS API Server only
• start-monitoring.sh - Monitoring interface only
• network-monitor.sh - Network connectivity monitoring

Service URLs:

• 🚀 SMS API Server: http://10.0.0.193:5001 (REST API for sending SMS)
• 📊 Monitoring Interface: http://10.0.0.193:5000 (Web dashboard for testing)

5. Verify Full System

# Test Ubuntu homelab → Android connection
curl http://localhost:5000/api/phone/status

# Test Android SMS API
curl http://10.0.0.193:5001/health

# Access web interfaces
open http://localhost:5000          # Main campaign manager
open http://10.0.0.193:5000         # Android monitoring dashboard

🔧 Service Management

Android Service Control

# Start all services
ssh android-dev "~/bin/start-all-services.sh"

# Individual service management
ssh android-dev "~/bin/sms-service.sh start"    # Start SMS API
ssh android-dev "~/bin/sms-service.sh stop"     # Stop SMS API  
ssh android-dev "~/bin/sms-service.sh status"   # Check SMS API status

# Restart monitoring interface
ssh android-dev "~/bin/start-monitoring.sh"

# View service logs
ssh android-dev "tail -f ~/logs/sms-api.log"
ssh android-dev "tail -f ~/logs/monitoring.log"

Auto-start on Boot (Optional)

# Add to Termux ~/.bashrc for auto-start
ssh android-dev
echo '~/bin/start-all-services.sh' >> ~/.bashrc

Service Health Monitoring

# Network connectivity monitoring
ssh android-dev "~/bin/network-monitor.sh"

# Complete system health check
curl http://10.0.0.193:5001/health && echo "SMS API: ✅" || echo "SMS API: ❌"
curl http://10.0.0.193:5000/ > /dev/null && echo "Monitor: ✅" || echo "Monitor: ❌"
curl http://localhost:5000/api/phone/status && echo "Homelab: ✅" || echo "Homelab: ❌"

• /dev/bus/usb:/dev/bus/usb - USB device access for ADB

---

📱 Android Setup

Method 1: ADB Wireless (Recommended)

1. Enable Developer Options on Android
2. Enable USB Debugging
3. Enable Wireless Debugging
4. Connect to same WiFi network as your homelab
5. Run ./auto.sh to auto-discover and connect

Method 2: Termux API Integration

1. Install Termux and Termux:API from F-Droid
2. Grant SMS permissions to Termux:API
3. Run ./setup-termux-integration.sh from your homelab
4. API server will run on port 5001

---

🎯 Usage Examples

Campaign Management

1. Access Web Interface: http://localhost:5000
2. Upload Contacts: CSV with phone, name, message columns
3. Create Campaign: Set message template with {name} variables
4. Monitor Progress: Real-time dashboard with analytics

CSV Format

phone,name,message
7802921731,Reed,Hi {name}! Your custom message here
7809101334,Ken,Hello {name}, different message per contact

Template Variables

• {name} - Contact name from CSV
• {phone} - Contact phone number
• Custom fields from your CSV columns

---

🧪 Testing & Troubleshooting

Health Checks

# Check Docker containers
docker-compose ps

# Test phone connectivity  
curl http://localhost:5000/api/phone/status

# View application logs
docker-compose logs sms-campaign

# Test SMS functionality
curl -X POST http://localhost:5000/api/sms/test \
  -H "Content-Type: application/json" \
  -d '{"phone":"YOUR_NUMBER","message":"Test message"}'

Common Issues

• Phone not connecting: Check IP address in .env and WiFi connectivity
• SMS not sending: Verify ADB connection and screen coordinates
• Permission denied: Ensure Docker has USB device access
• Database errors: Check volume mounts and file permissions

🚨 Troubleshooting

Android Service Issues

# Check if services are running
ssh android-dev "ps aux | grep -E '(termux-sms-api|python.*app.py)'"

# Restart all services
ssh android-dev "pkill -f 'termux-sms-api-server.py'; pkill -f 'python app.py'"
ssh android-dev "~/bin/start-all-services.sh"

# Check service logs for errors
ssh android-dev "tail -20 ~/logs/sms-api.log"
ssh android-dev "tail -20 ~/logs/monitoring.log"

# Test Termux API permissions
ssh android-dev "termux-sms-list -l 1"  # Should list recent SMS

### Reinstall if services are corrupted
```bash
# Redeploy scripts to ~/bin/
scp -P 8022 android/*.sh android-dev@10.0.0.193:~/bin/
ssh android-dev "chmod +x ~/bin/*.sh"

# Redeploy Python apps to ~/projects/sms-campaign-manager/
scp -P 8022 android/*.py android-dev@10.0.0.193:~/projects/sms-campaign-manager/

# Restart services
ssh android-dev "~/bin/start-all-services.sh"

Service Port Conflicts

# Check what's using ports 5000/5001
ssh android-dev "netstat -tlnp | grep -E ':500[01]'"

# Kill processes on specific ports
ssh android-dev "lsof -ti:5001 | xargs kill -9"
ssh android-dev "lsof -ti:5000 | xargs kill -9"

Phone Not Connecting

# Auto-reconnect your phone
./auto.sh

# Check ADB devices
adb devices

# Restart connection monitoring
./phone-auto-connect.sh restart

Termux API Issues

# Test Termux API health
curl http://10.0.0.193:5001/health

# Restart Termux API server
ssh android-dev "cd ~/projects/sms-campaign-manager && python termux-sms-api-server.py"

Docker Deployment Issues

# Rebuild containers
docker-compose down && docker-compose up --build

# Check logs
docker-compose logs -f
