RAK4631 + ethernet not working?

Support
1

Recently discovered Meshtastic and bought a RAK4631 + ethernet board to experiment with. But for whatever reason the Ethernet DHCP doesn’t seem to work for me and I get the following output:

??:??:?? 1 Meshtastic hwvendor=9, swver=2.0.10.e09b12c-d
....
??:??:?? 3 starting Ethernet DHCP
??:??:?? 63 Unknown Ethernet error.

Is this a known issue? Everything else on my network seems happy enough being issued an address (I even checked using exactly the same cable and switch port … just in case … works fine with a laptop). Any pointers on how to debug this?

Thanks

Just adding some more information:

Plugged into a USB ethernet connector → Mac → dnsmasq … gets an IP address
Plugged into a Mikrotik CRS309-1G-8S+ → lights up but no traffic at the switch
Pluggeg into a Mikrtok HAP AC2 → doesnt even light up and claims cable is not connected (cable is, and same cable in all tests).

Hmm. The ethernet address of this device is ed:c1:da:84:d3:bd … and this is a multicast ethernet address which is not what you want here :frowning: Is there a fix for this?

4

If I kill the multicast bit in the ethernet address - so it becomes ec:c1:da:84:d3:bd - it all works as you’d hope. Will submit a PR.

Thanks for the Pull Request. These Ethernet boards don’t come with a harware MAC like you would expect so i was hijacking the BLE Mac which apparently doesn’t care about the multicast bit at all. The fix will be in the next firmware.

I’m struggling getting the RAKs to work on ethernet, installed 2.0.14 and enabled ethernet but no cigar. Am using known good settings from a t-beam, but with ethernet enabled instead of wifi. Any guidance or suggestions? I need to see if I can get som serial output once ethernet is enabled, I was struggling with that too once I enabled ethernet

What do you see on the serial port? It does not really require any config.

Hi garth, I was struggling to get any serial output - it seems like the ethernet is a bit picky about when one plugs in the ethernet cable. plugging it in when the RAK is switched off and then sullpying power yields a

ERROR | ??:??:?? 67 Ethernet cable is not connected.

but restarting the divice then allows it to connect. This is the furthest I have managed to get a serial output, it often seems to crash or stop before I can send a message:

after this the device is just stuck. Interestingly enough, even though the message “Testing” was clearly received by the ethernet enabled RAK, the RAK it was sent from shows both this message and any subsequent messages as “Max retransmission Reached” in iOS

on occasion the final line in the terminal output is

Another obervation I have is that the ethernet cable must be short for the lights on the ethernetport to come on - 1m long cables always result in ERROR | ??:??:?? 67 Ethernet cable is not connected, but a 30 cm cable can work.

Same result with another baseboard, and another ethernet port:

Cant comment on your specific setup, but I have two RAK4631 + ethernet working fine on cables of 50 feet. Both are running 2.0.13.

Tested again as I had used two different routers, a mobile router and a google mesh router. Whilst the mesh router has access to the internet via ethernet, it won’t light up the lights and connect to the RAK with what ever length cable, whereas the mobile trouter will. So NOT a cable length issue, you’re right, but probably related to some settings on the google mesh router.

We’re having issues with the same core and Ethernet module with Poe board

Specifically the module gets an IP and responds to ping, but does not reply to requests from CLI using --host.

@Nanovitruvius did you ever get these modules connected and working over IP?
