||||
```
|
||||
Card Inserted
|
||||
↓ (5 seconds later, batched)
|
||||
API Post
|
||||
↓
|
||||

|
||||
```
|
||||
|
||||
### After (New System)
|
||||
```
|
||||
Card Inserted
|
||||
↓ (immediate)
|
||||
LED ON
|
||||
↓ (<1 second)
|
||||
API Post
|
||||
↓
|
||||
User sees instant feedback
|
||||
```
|
||||
|
||||
### Before (Debugging)
|
||||
```
|
||||
Error in card event?
|
||||
→ Check rfid_module.py
|
||||
→ Check logger_batch_module.py
|
||||
→ Check connectivity_module.py
|
||||
→ Check led_module.py
|
||||
→ Check app.py
|
||||
→ Trace through 10+ files
|
||||
→ Takes 1+ hours
|
||||
```
|
||||
|
||||
### After (Debugging)
|
||||
```
|
||||
Error in card event?
|
||||
→ Check app_v3_simplified.py
|
||||
→ Search for the error message
|
||||
→ Found in ~5 minutes
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎓 WHAT YOU LEARNED
|
||||
|
||||
The old app had a good architecture in theory (modular, clean), but in practice:
|
||||
- **Too complex** for this simple use case
|
||||
- **Added delays** through batch logging
|
||||
- **Hard to debug** with 10+ interdependent modules
|
||||
- **Over-engineered** with features not needed
|
||||
|
||||
The new approach is:
|
||||
- **Keep it simple** - one file, clear logic
|
||||
- **Direct communication** - no intermediaries
|
||||
- **Easy to modify** - all code in one place
|
||||
- **Easier to debug** - trace one file top to bottom
|
||||
|
||||
This is a practical lesson in **YAGNI** (You Ain't Gonna Need It) - sometimes simpler is better!

## 📞 SUPPORT
|
||||
|
||||
### If Something Goes Wrong
|
||||
|
||||
1. **Check the logs:**
|
||||
```bash
|
||||
tail -100 ./data/log.txt
|
||||
```
|
||||
|
||||
2. **Look for error patterns:**
|
||||
- "RFID reader failed" → Hardware issue
|
||||
- "Failed to send log" → Network issue
|
||||
- "Offline: Saving" → Expected behavior
|
||||
- "No response" → WiFi down
|
||||
|
||||
3. **Consult documentation:**
|
||||
- `SIMPLIFIED_V3_GUIDE.md` - Troubleshooting section
|
||||
- `TESTING_VERIFICATION_CHECKLIST.md` - Test guide
|
||||
|
||||
4. **Verify manually:**
|
||||
```bash
|
||||
# Can RFID reader be accessed?
|
||||
cat /dev/ttyS0
|
||||
|
||||
# Is internet available?
|
||||
ping 10.76.140.17
|
||||
|
||||
# Can we POST to API?
|
||||
curl -X POST "https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/test/12345/1/2025-12-18&14:00:00" --insecure
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🏆 SUCCESS CRITERIA
|
||||
|
||||
Your system is working correctly when:
|
||||
|
||||
✅ App starts without errors
|
||||
✅ Insert card → LED ON, log shows "🔴 CARD INSERTED"

|
||||
## 📊 Code Comparison
|
||||
|
||||
### Old Way: Sending Card Event
|
||||
```python
|
||||
# rfid_module.py
|
||||
queue_log_message(msg, hostname, device_ip)
|
||||
|
||||
# This goes to logger_batch_module.py
|
||||
def queue_log_message(msg, hostname, device_ip):
|
||||
batch_queue.put((msg, hostname, device_ip))
|
||||
# Waits for 5 messages or 5 seconds...
|
||||
|
||||
# Then batch_logger_worker thread processes it
|
||||
def batch_worker():
|
||||
# Every 5 seconds or 10 items:
|
||||
send_log_to_server(batch_data)
|
||||
```
|
||||
**Result:** 0-5 second delay
|
||||
|
||||
### New Way: Sending Card Event
|
||||
```python
|
||||
# app_v3_simplified.py (same file)
|
||||
send_log_to_server(f"Card {card_id} inserted", hostname, device_ip, name)
|
||||
|
||||
def send_log_to_server(message, hostname, device_ip, name):
|
||||
response = requests.post(server_url, json=log_data, timeout=5)
|
||||
```
|
||||
**Result:** Immediate post, <1 second
|
||||
|
||||
## 🔄 Migration Checklist

|
||||
## Quick Start
|
||||
|
||||
### 1️⃣ Prerequisites
|
||||
```bash
|
||||
# Install rdm6300 if not already installed
|
||||
pip3 install rdm6300
|
||||
|
||||
# Ensure you have the dialout group permission
|
||||
sudo usermod -a -G dialout $USER
|
||||
# (logout/login required)
|
||||
|
||||
# Verify serial device exists
|
||||
ls /dev/ttyS0 # Should exist
|
||||
```
|
||||
|
||||
### 2️⃣ Configure Device ID
|
||||
```bash
|
||||
# Set your device name (e.g., mesa_1, mesa_2, etc.)
|
||||
echo "mesa_1" > ./data/idmasa.txt
|
||||
```
|
||||
|
||||
### 3️⃣ Start the Application
|
||||
```bash
|
||||
cd /home/pi/Desktop/prezenta_work
|
||||
python3 app_v3_simplified.py
|
||||
```
|
||||
|
||||
### 4️⃣ Expected Output
|
||||
```
|
||||
============================================================
|
||||
RFID CARD READER - Simplified v3.0
|
||||
============================================================
|
||||
|
||||
✓ Logging configured: ./data/log.txt
|
||||
✓ LED initialized on GPIO 23
|
||||
Device: raspberry (192.168.1.50)
|
||||
Name ID: mesa_1
|
||||
✓ RFID reader started on /dev/ttyS0
|
||||
✓ WiFi monitor started
|
||||
✓ RFID Client operational - waiting for cards...
|
||||
```
|
||||
|
||||
### 5️⃣ Test with a Card
|
||||
- Insert card → LED turns ON → logs show "🔴 CARD INSERTED"
|
||||
- Remove card → LED turns OFF → logs show "⚪ CARD REMOVED"
|
||||
|
||||
---
|
||||
|
||||
## How It Works
|
||||
|
||||
### Card Event Flow
|
||||
```
|
||||
Card Presented
|
||||
↓
|
||||
RFID Reader detects
|
||||
↓
|
||||
card_inserted() or card_removed() called
|
||||
↓
|
||||
LED ON/OFF (immediate visual feedback)
|
||||
↓
|
||||
Build API URL with timestamp
|
||||
↓
|
||||
Try POST to Harting API
|
||||
├─ ✅ Success → Log to monitoring server
|
||||
└─ ❌ Offline → Save URL to tag.txt for later
|
||||
```
|
||||
|
||||
### WiFi Recovery Flow
|
||||
```
|
||||
Every 40 minutes:
|
||||
↓
|
||||
Ping 10.76.140.17
|
||||
├─ ✅ Responds
|
||||
│ ├─ Upload any backed-up data from tag.txt
|
||||
│ └─ Wait 40 minutes
|
||||
└─ ❌ No response
|
||||
├─ Log: "Connection lost"
|
||||
├─ Disable WiFi: sudo rfkill block wifi
|
||||
├─ Wait 20 minutes
|
||||
├─ Enable WiFi: sudo rfkill unblock wifi
|
||||
└─ Try again
|
||||
```
|
||||
|
||||
### Offline Backup Flow
|
||||
```
|
||||
When offline (no network):
|
||||
├─ Insert card → Save URL to tag.txt
|
||||
├─ Remove card → Save URL to tag.txt
|
||||
└─ (Data stays in tag.txt until connection restored)
|
||||
|
||||
When online again:
|
||||
├─ WiFi check succeeds
|
||||
├─ Read tag.txt (all backed-up URLs)
|
||||
├─ POST each URL to Harting API
|
||||
├─ If success → remove from tag.txt
|
||||
└─ If fail → keep for next retry
|
||||
```

### Immediate (Today)
|
||||
1. ✅ Review `SIMPLIFIED_V3_GUIDE.md`
|
||||
2. ✅ Read `COMPARISON_QUICK_REFERENCE.md`
|
||||
3. ✅ Set device ID in `./data/idmasa.txt`
|
||||
4. ✅ Start new app: `python3 app_v3_simplified.py`
|
||||
|
||||
### Testing (First Run)
|
||||
1. ✅ Insert test card → verify LED feedback + logs
|
||||
2. ✅ Remove card → verify LED OFF + logs
|
||||
3. ✅ Disconnect WiFi → verify offline backup
|
||||
4. ✅ Reconnect WiFi → verify backup posted
|
||||
5. ✅ Monitor for WiFi check (every 40 min)
|
||||
|
||||
### Production (After Testing)
|
||||
1. ⚙️ Update systemd service to use new app
|
||||
```bash
|
||||
sudo systemctl edit rfid-reader.service
|
||||
# Change ExecStart to: /usr/bin/python3 /home/pi/Desktop/prezenta_work/app_v3_simplified.py
|
||||
```
|
||||
|
||||
2. ⚙️ Set up monitoring dashboard to track:
|
||||
- Card events arriving at Harting API
|
||||
- Logs arriving at monitoring server
|
||||
- WiFi recovery events
|
||||
- No backed-up data in tag.txt (indicates all online)
|
||||
|
||||
3. ⚙️ (Optional) Archive old files:
|
||||
```bash
|
||||
mkdir old_modules
|
||||
mv rfid_module.py led_module.py logger_batch_module.py old_modules/
|
||||
mv app.py app.py.archive
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "RFID reader failed"
|
||||
```
|
||||
Check: ls /dev/ttyS0
|
||||
Fix: Enable UART in raspi-config or check RFID hardware connection
|
||||
```
|
||||
|
||||
### "No cards being detected"
|
||||
```
|
||||
Check: cat /dev/ttyS0 (present card, should see data)
|
||||
Fix: Verify card is RDM6300 compatible
|
||||
```
|
||||
|
||||
### "LED not turning on"
|
||||
```
|
||||
Check: gpio readall | grep 23
|
||||
Fix: LED on GPIO 23 may not be connected, check wiring
|
||||
Note: App continues to work even if LED fails
|
||||
```
|
||||
|
||||
### "Data not posting to Harting"
|
||||
```
|
||||
Check: tail -f ./data/log.txt
|
||||
Look for: "✗ Offline: Saving card" (means no network)
|
||||
Fix: Verify internet connection: ping 10.76.140.17
|
||||
```
|
||||
|
||||
### "tag.txt keeps growing"
|
||||
```
|
||||
Means: Harting API is not accepting the POSTs
|
||||
Check: Internet connection
|
||||
Check: Harting API URL is correct
|
||||
Check: Device ID (idmasa.txt) is correct
|
||||
```

# RFID System - Simplified Version 3.0 Guide
|
||||
|
||||
## Overview
|
||||
|
||||
The new simplified `app_v3_simplified.py` is a clean, focused rewrite that:
|
||||
- Eliminates unnecessary complexity from the previous multi-module architecture
|
||||
- Maintains all **core functionality** that was working in the old v2.7
|
||||
- Provides better error handling and logging
|
||||
- Ensures WiFi recovery works properly
|
||||
- Handles offline card data backup to `tag.txt`
|
||||
|
||||
## What's Different
|
||||
|
||||
### Old Architecture (Complex)
|
||||
```
|
||||
app.py (main)
|
||||
├── rfid_module.py (RFID handling)
|
||||
├── led_module.py (LED control)
|
||||
├── logger_batch_module.py (batch logging)
|
||||
├── connectivity_module.py (internet check)
|
||||
├── wifi_recovery_module.py (WiFi restart)
|
||||
├── dependencies_module.py (dependency management)
|
||||
├── device_module.py (device info)
|
||||
└── ... other modules
|
||||
```
|
||||
|
||||
**Problems:**
|
||||
- Too many interdependencies
|
||||
- Message passing between modules was complex
|
||||
- Batch logging added unnecessary latency
|
||||
- Multiple modules doing similar things
|
||||
- Hard to debug which component failed
|
||||
|
||||
### New Architecture (Simplified)
|
||||
```
|
||||
app_v3_simplified.py (single file, ~300 lines)
|
||||
├── RFID Reader (card detection)
|
||||
├── LED Control (visual feedback)
|
||||
├── Server Communication (logs + API posts)
|
||||
├── WiFi Monitor (connection + recovery)
|
||||
└── Main Loop (orchestration)
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- All logic in one file, easy to understand flow
|
||||
- Direct server communication (no batching delays)
|
||||
- Clear separation of concerns
|
||||
- Easier to debug and modify
|
||||
- Same functionality, 1/3 the complexity
|
||||
|
||||
## Core Functionality
|
||||
|
||||
### 1. Card Detection & Posting
|
||||
```
|
||||
When card inserted (value != 12886709):
|
||||
├─ Turn LED ON
|
||||
├─ Build URL: https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/{name}/{card_id}/1/{timestamp}
|
||||
├─ Try POST immediately
|
||||
├─ If OK: Log to monitoring server
|
||||
└─ If FAIL: Save to tag.txt for later
|
||||
|
||||
When card removed:
|
||||
├─ Turn LED OFF
|
||||
├─ Build URL: https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/{name}/{card_id}/0/{timestamp}
|
||||
├─ Try POST immediately
|
||||
├─ If OK: Log to monitoring server
|
||||
└─ If FAIL: Save to tag.txt for later
|
||||
```
|
||||
|
||||
### 2. WiFi Recovery (Every 40 Minutes)
|
||||
```
|
||||
Loop every 40 minutes:
|
||||
├─ Ping 10.76.140.17
|
||||
├─ If responds (OK):
|
||||
│ ├─ Process backed-up data from tag.txt
|
||||
│ ├─ Send to Harting API
|
||||
│ └─ Wait 40 minutes
|
||||
└─ If no response (FAIL):
|
||||
├─ Log to monitoring server: "WiFi connection lost"
|
||||
├─ Disable WiFi: sudo rfkill block wifi
|
||||
├─ Wait 20 minutes
|
||||
├─ Enable WiFi: sudo rfkill unblock wifi
|
||||
└─ Check again
|
||||
|
||||
All WiFi actions logged to monitoring server.
|
||||
```
|
||||
|
||||
### 3. Offline Card Data Backup
|
||||
```
|
||||
When connection is DOWN and card activity occurs:
|
||||
└─ Save URL to tag.txt:
|
||||
https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/{name}/{card_id}/0/{timestamp}
|
||||
|
||||
When connection comes BACK UP:
|
||||
├─ Read tag.txt
|
||||
├─ POST each URL to Harting API
|
||||
├─ Remove from tag.txt on success
|
||||
└─ Keep on retry fail
|
||||
```
|
||||
|
||||

|
||||
## API Endpoints
|
||||
|
||||
### 1. Card Event Data (Harting API)
|
||||
**URL Format:**
|
||||
```
|
||||
https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/{name}/{card_id}/{state}/{timestamp}
|
||||
```
|
||||
|
||||
**Parameters:**
|
||||
- `{name}`: Device ID from `idmasa.txt` (e.g., "mesa_1")
|
||||
- `{card_id}`: RFID card number (e.g., 12345678)
|
||||
- `{state}`: 1 = card inserted (ON), 0 = card removed (OFF)
|
||||
- `{timestamp}`: Date & time in format `YYYY-MM-DD&HH:MM:SS`
|
||||
|
||||
**Example:**
|
||||
```
|
||||
https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/mesa_1/12345678/1/2025-12-18&14:23:45
|
||||
```
|
||||
|
||||
### 2. Monitoring Server Logs
|
||||
**URL:** `http://rpi-ansible:80/logs`
|
||||
|
||||
**POST Data:**
|
||||
```json
|
||||
{
|
||||
"hostname": "raspberry",
|
||||
"device_ip": "192.168.1.50",
|
||||
"nume_masa": "mesa_1",
|
||||
"log_message": "Card 12345678 inserted"
|
||||
}
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: "RFID reader failed - application cannot continue"
|
||||
**Solution:**
|
||||
1. Check serial device: `ls /dev/tty*`
|
||||
2. If `/dev/ttyS0` not visible, enable UART: `sudo raspi-config` → Interface Options → Serial Port
|
||||
3. Check permissions: `sudo usermod -a -G dialout $USER` (then logout/login)
|
||||
4. Reboot if needed
|
||||
|
||||
### Issue: WiFi not recovering properly
|
||||
**Solution:**
|
||||
1. Check if WiFi is blocking: `sudo rfkill list wifi`
|
||||
2. Manually test: `sudo rfkill block wifi && sleep 5 && sudo rfkill unblock wifi`
|
||||
3. Check monitoring server logs for WiFi recovery events
|
||||
4. Verify ping target `10.76.140.17` is reachable
|
||||
|
||||
### Issue: Card events not posting to Harting API
|
||||
**Solution:**
|
||||
1. Check `tag.txt` for backed-up URLs (indicates network is down)
|
||||
2. Verify internet connection: `ping -c 3 10.76.140.17`
|
||||
3. Test API URL manually: `curl -X POST "https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record/test/12345/1/2025-12-18&14:00:00"`
|
||||
4. Check app logs: `tail -f ./data/log.txt`
|
||||
|
||||
### Issue: LED not turning on/off
|
||||
**Solution:**
|
||||
1. Check GPIO pin 23 is available: `gpio readall` (requires wiringpi)
|
||||
2. Check gpiozero is installed: `python3 -c "from gpiozero import OutputDevice"`
|
||||
3. If GPIO unavailable, app uses dummy LED that just prints messages (not an error)
|
||||
|
||||
## Migration from Old Version
|
||||
|
||||
### Step 1: Verify Old System Working
|
||||
```bash
|
||||
# Test old app.py
|
||||
python3 app.py
|
||||
# Insert card, verify it posts to both servers
|
||||
# Check: monitoring server logs + harting API + LED feedback
|
||||
```
|
||||
|
||||
### Step 2: Stop Old App
|
||||
```bash
|
||||
# If running in screen/tmux
|
||||
Ctrl+C
|
||||
|
||||
# If running as service
|
||||
sudo systemctl stop prezenta (or similar)
|
||||
```
|
||||
|
||||
### Step 3: Use New App
|
||||
```bash
|
||||
# Just rename or switch
|
||||
python3 app_v3_simplified.py
|
||||
```
|
||||
|
||||
### Step 4: Verify New System
|
||||
```bash
|
||||
# Insert test card
|
||||
# Expected logs in ./data/log.txt:
|
||||
# - 🔴 CARD INSERTED
|
||||
# - ✓ Card event posted to API
|
||||
|
||||
# Check monitoring server received the log
|
||||
# Check Harting API shows the card event
|
||||
# Verify LED turned on then off
|
||||
```
|
||||
|
||||

||||
| Card Post Latency | 5s (batch) | <1s (direct) | 5x faster feedback |
|
||||
| WiFi Recovery Time | Variable | Fixed 20 min | Predictable |
|
||||
| Debugging | Multiple modules | Single file | 10x easier |
|
||||
|
||||
## Configuration Reference
|
||||
|
||||
All configuration is hardcoded in `app_v3_simplified.py`. To change, edit these constants:
|
||||
|
||||
```python
|
||||
# Server URLs
|
||||
MONITORING_SERVER = "http://rpi-ansible:80/logs"
|
||||
HARTING_API_BASE = "https://dataswsibiusb01.sibiusb.harting.intra/RO_Quality_PRD/api/record"
|
||||
WIFI_CHECK_HOST = "10.76.140.17"
|
||||
|
||||
# Timings
|
||||
WIFI_CHECK_INTERVAL = 2400 # 40 minutes
|
||||
WIFI_RECOVERY_WAIT = 1200 # 20 minutes
|
||||
|
||||
# Hardware
|
||||
LED_PIN = 23 # GPIO pin for LED
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. ✅ Test new app with actual RFID cards
|
||||
2. ✅ Verify WiFi recovery works
|
||||
3. ✅ Monitor logs for any issues
|
||||
4. ✅ Once stable, replace old app.py with new version
|
||||
5. ✅ Set up automatic restart (systemd service or cron)
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues occur with new version:
|
||||
```bash
|
||||
# Kill new app
|
||||
Ctrl+C
|
||||
|
||||
# Restore old version
|
||||
cp app.py.backup app.py
|
||||
python3 app.py
|
||||
```
|
||||
|
||||
All old modules are still in place, so rollback is safe.

|
||||
|
||||
### App crashes immediately
|
||||
```bash
|
||||
# Check logs
|
||||
tail -50 ./data/log.txt
|
||||
|
||||
# Common issues:
|
||||
# 1. rdm6300 not installed: pip3 install rdm6300
|
||||
# 2. Serial device not found: ls /dev/tty*
|
||||
# 3. Permission denied: sudo usermod -a -G dialout $USER
|
||||
```
|
||||
|
||||
### Card inserted but no LED/log
|
||||
```bash
|
||||
# 1. Check RFID reader connected: cat /dev/ttyS0 (present card, should see data)
|
||||
# 2. Check LED wired to GPIO 23
|
||||
# 3. Check device permissions: ls -la /dev/ttyS0
|
||||
# 4. Restart app
|
||||
```
|
||||
|
||||
### Server not receiving logs
|
||||
```bash
|
||||
# 1. Check network: ping 10.76.140.17
|
||||
# 2. Check server running: ps aux | grep monitoring
|
||||
# 3. Check firewall: sudo ufw status
|
||||
# 4. Check log for errors: grep ERROR ./data/log.txt
|
||||
```
|
||||
|
||||
### WiFi recovery not working
|
||||
```bash
|
||||
# 1. Check WiFi can be blocked: sudo rfkill block wifi
|
||||
# 2. Check it was unblocked: sudo rfkill unblock wifi
|
||||
# 3. Check sudo permissions: sudo -l | grep rfkill
|
||||
# 4. Test manual: sudo rfkill block wifi && sleep 5 && sudo rfkill unblock wifi
|
||||
```
