- MrDrMcCoy 2mo agoSource? HDMI includes Ethernet in the spec, but I've never heard of any devices actually implementing it.
- RiverCrochet 2mo agoThat would require the Roku to specifically be set up to act as a router. You can't just connect to a random device that's not specifically a router/AP and use its internet connection. Since Roku like other smart TV companies makes money off of user data captur, it's not incentivized to enable those conditions for a downstream device, especially if not specifically advertised as a feature.
- toast0 2mo agoIf this was a feature they wanted to provide, it would simplest to set the Roku up as a bridge. No dhcp, no nat, just a virtual switch. Roku devices run on Linux, if their HDMI chip supports Ethernet and that's plumbed to a Linux supported MAC (probably not), it might take an hour to build and test the feature. Longer if the wifi interface doesn't like being bridged (I've seen that on some openwrt devices). There's esp-idf examples from espressif for doing bridging on an esp32 if you have one with a MAC and a PHY and/or spi mac+phy. Or for wired ethernet, they could include a three port switch IC.
- walrus01 2mo agodoes a roku provide a dhcp server, issue a dhcp lease, do NAT and routing to things that are plugged into it over the 100M ethernet built into a current gen HDMI link?
- mikestew 2mo agoThis again? Yes, it’s in the spec. No, no one has been shown to have actually implemented it. No streaming box is going to allow random devices to use their connection.
- toast0 2mo agoE-Arc uses the wires intended for Ethernet. Hook your Roku up to an earc port if you're seriously concerned about it.
