Has anyone been able to share wifi with a Particle device over ethernet - specifically Xenon + Ethernet shield?
- Raspberry Pi 3 connected to internet over wifi
- Particle Xenon + Ethernet shield connected to Pi over ethernet
I am trying with the following script, but it only keeps flashing one of the following
- Cyan - where it is trying to connect but never does
- Orange (red/yellow) - where it hits an error in the connection
It seems like it should be possible, right?
