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:
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?
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 Is there a fix for this?
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.
