+## Common Compilation Issues - 112025 (Arduino Opta)
+
+### 1. ArduinoJson Version Mismatch
+
+**Problem:** `no matching function for call to 'JsonDocument::JsonDocument(int)'`
+
+**Solution:** Ensure you have ArduinoJson version 7.x or later:
+- ArduinoJson 7.x uses `JsonDocument` instead of `DynamicJsonDocument`
+- Install via Library Manager: Search "ArduinoJson" and install version 7.2.0 or later
+- Version 6.x will not work with the 112025 code
+
+### 2. Notecard Library Missing
+
+**Problem:** `Notecard.h: No such file or directory`
+
+**Solution:** Install Blues Wireless Notecard library:
+- Open Library Manager
+- Search: "Notecard"
+- Install: "Blues Wireless Notecard by Blues Inc."
+
+### 3. LittleFS Not Found
+
+**Problem:** `LittleFS.h: No such file or directory`
+
+**Solution:** LittleFS is built into Arduino Mbed OS core:
+- Go to **Tools → Board → Boards Manager**
+- Search: "Arduino Mbed OS Opta Boards"
+- Install the package
+- LittleFS will be automatically available
+
+### 4. Wrong Board Selected
+
+**Problem:** `#error "This sketch is designed for Arduino Opta"`
+
+**Solution:** Ensure correct board is selected:
+- Go to **Tools → Board → Arduino Mbed OS Opta Boards**
+- Select **Arduino Opta**
+- FQBN should be: `arduino:mbed_opta:opta`
+
+### 5. Ethernet Library Issues
+
+**Problem:** Ethernet-related compilation errors (server only)
+
+**Solution:** 
+- Ethernet library should be built-in
+- If missing, install via Library Manager: "Ethernet by Arduino"
+- Ensure you're compiling the server, not the client (client doesn't use Ethernet)

 # Quick Reference: Fleet-Based vs Route-Based Setup
 
+## Arduino IDE Setup (112025)
+
+### Required Software
+- **Arduino IDE** 2.0+ (recommended) or 1.8.x
+- **Board Support:** Arduino Mbed OS Opta Boards (via Boards Manager)
+
+### Required Libraries (Install via Library Manager)
+1. **ArduinoJson** (version 7.x or later) - JSON parsing
+2. **Blues Wireless Notecard** (latest) - Notecard communication
+3. **Ethernet** (built-in) - Web server (server only)
+4. **LittleFS** (built-in with Mbed core) - File system
+5. **Wire** (built-in) - I2C communication
+
+### Installation Steps
+1. Install Arduino IDE from [arduino.cc/software](https://www.arduino.cc/en/software)
+2. Open **Tools → Boards Manager** → Search "Arduino Mbed OS Opta Boards" → Install
+3. Open **Tools → Manage Libraries** → Install libraries listed above
+4. Open sketch (.ino file) for client or server
+5. Select **Tools → Board → Arduino Opta**
+6. Update `PRODUCT_UID` (client) or `SERVER_PRODUCT_UID` (server) to match your Blues Notehub project
+7. Compile and upload

-## Version 092025 (Current - Recommended)
+## Version 112025 (Blues Wireless + Arduino Opta)
+
+The 112025 version uses Arduino Opta with Blues Wireless Notecard for cellular connectivity. Features include:
+- **Internal flash storage** (LittleFS) - No SD card required
+- **Fleet-based communication** - Simplified device-to-device data exchange via Blues Notehub
+- **Web-based configuration** - Update clients remotely from server dashboard
+- **Intranet dashboard** - Real-time monitoring via Ethernet web interface

+
+### Configuration Approach (112025)
+
+The 112025 version uses a **simplified configuration system**:
+
+1. **LittleFS Internal Storage** - Configuration persisted to device flash
+   - No SD card required
+   - Survives power cycles
+   - Automatic default config on first boot
+
+2. **Remote Configuration** - Update clients via server web interface
+   - Push config changes from server to any client
+   - Changes routed through Blues Notehub
+   - No physical access needed for updates
+
+3. **Fleet-Based Communication** - Simplified device-to-device routing
+   - Just assign devices to fleets in Blues Notehub
+   - No manual route configuration needed
+   - Easier scaling for multiple devices
+
+## Version 092025 (Current - Recommended for MKR NB 1500)
 
 The 092025 version is the latest implementation using Arduino MKR NB 1500 with Hologram.io cellular connectivity.
