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
