Ethernet Hotspot

Ethernet Hotspot provides wired network access to OpenHD video and telemetry data.

Overview​

Ethernet Hotspot enables:

  • Wired Connection: Stable network connection via Ethernet
  • Higher Bandwidth: Better performance than WiFi
  • Multiple Device Support: Connect switches/hubs for multiple devices
  • Reliable Connection: Less interference than wireless

Hardware Requirements​

Ethernet Adapter​

  • USB-to-Ethernet Adapter: For Raspberry Pi models without built-in Ethernet
  • Built-in Ethernet: Pi 3B+, Pi 4 have built-in Gigabit Ethernet
  • Powered Hub: For multiple device connections

Cables and Switches​

  • Ethernet Cables: Cat5e or Cat6 recommended
  • Network Switch: For connecting multiple devices
  • Power Considerations: Ensure adequate power for all devices

Configuration​

Network Settings​

  • IP Range: 192.168.2.x
  • Gateway: 192.168.2.1
  • DHCP Server: Automatic IP assignment
  • Subnet Mask: 255.255.255.0

Enable Ethernet Hotspot​

  1. Connect Ethernet adapter/cable
  2. Access OpenHD network settings
  3. Enable "Ethernet Hotspot"
  4. Configure IP range if needed
  5. Save and restart networking

Device Connection​

Direct Connection​

  1. Connect device directly via Ethernet cable
  2. Configure network settings (automatic or manual)
  3. Access OpenHD services at gateway IP
  4. Launch appropriate software

Through Network Switch​

  1. Connect OpenHD and devices to network switch
  2. Ensure all devices in same IP range
  3. Configure device network settings
  4. Access OpenHD services

Ground Control Integration​

Computer Connection​

  1. Connect computer via Ethernet
  2. Launch ground control software
  3. Connect to OpenHD IP address (192.168.2.1)
  4. Configure MAVLink connection if needed

Streaming Devices​

  1. Connect streaming device via Ethernet
  2. Configure video input source
  3. Set input to OpenHD IP stream
  4. Configure resolution and quality settings
