Ethernet
The Ethernet feature provides general network configuration and management capabilities for your AppBlocks device. This includes IP configuration and DHCP configuration.
Overview
Network configuration controls:
- IP address assignment (DHCP or static)
- Gateway and routing settings
IP Configuration
DHCP (Dynamic Host Configuration Protocol)
Automatic IP configuration (default):
- IP address assigned by DHCP server
- DNS servers provided automatically
- Gateway and subnet configured automatically
- Simplest configuration for most networks
Static IP Configuration
Manual IP address assignment:
- IP Address: Device IP address
- Subnet Mask: Network subnet (e.g., 255.255.255.0)
- Gateway: Router IP address
Static IP is useful for:
- Server applications requiring consistent addresses
- Networks without DHCP servers
- Device-to-device communication
- Firewall rule configurations
Linking to Settings
Network properties can be linked to settings for:
- Site-specific configurations
- Multi-location deployments
- Field reconfiguration without code changes
Related Features
- WiFi: Wireless configuration
- Cellular: Mobile data
- HTTP Server: Web services
- MQTT: Cloud messaging
- Socket: TCP/IP communication
Use Cases
Common network configuration scenarios:
- Industrial networks with static IP requirements
- Multi-site deployments with different network setups
- Failover between WiFi and cellular
- VPN connectivity for secure remote access
- Local device-to-device communication
Troubleshooting
Common network issues:
- No connectivity: Check cable, WiFi, or cellular configuration
- Cannot reach internet: Verify gateway and DNS settings
- Local access only: Check gateway and routing configuration
- Slow performance: Check network congestion and signal strength
