Ethernet Idea

Needs bench validation

• Airside android acts as a subnet router for pi and pixhawk

• Note 8 may not support ethernet tethering. In that case another member will need to donate an old phone or we will have to buy another one (such as S21 FE, must be Android 11+)

• Do android phones support multiple ethernet clients? Need to find out

• Alternatively the Pi runs Tailscale and android just as WAN access. This means telem depends on the pi though, which is not preferable. Update 2025-05-21: This is the only way to go, Android doesn’t route tethering traffic through VPNs

• Tested and working USB-C to Ethernet adapter on Android: https://a.co/d/iqSJfRb

General outline for testing:

1. Research setup, list and source all components required (1 week)

2. Order any components WARG does not already own (~1 week)

   1. While waiting for component delivery, connect the Pixhawk and a laptop to the router we already own and figure out how to connect to it locally via Mission Planner.

   2. Set up a subnet router on the laptop using Tailscale. Connect to the pi via the internet from the WARG desktop. This is very similar to the setup to be used on the drone and will provide valuable background.

3. Assemble airside system and test on bench

Parts List

RJ45 to JST-GH adapters will have to be made for this to work. They can be directly soldered or a simple PCB can be designed.
