Libresdr Physical Ethernet Connection [FIXED]

[xtranerd]

Hi - I'm trying to use the Libresdr on its dedicated Ethernet connector. I am trying to power the Libresdr with a 5V PSU on the OTG or DEBUG input and connect to the device via 192.168.0.116 remotely.

I can only connect using Windows 10 with the USB OTG connected using SDRConsole.

However on Linux (Debian 12) I can connect via SSH and also receive using SDR++ via the physical Ethernet connector (I must connect OTG USB to the PC) - and SDR++ reception stops when I disconnect the Ethernet cable. This indicates that I am connected via the physical ethernet connection.

If I supply just 5 V to either the OTG or Debug USB connectors -the Libresdr does not work at all (the LEDs do light up though)

Any ideas - I don't want to connect to the LIbresdr via the USB ports

Many thanks,

James G1PVZ

When you work on gigabitEthernet, you need to set up under USB_ETHERNET chapter.
With your config, as no ip is set, it requires a dhcp sever on your network.
You can also set manual ip by setting ipaddr_eth and gateway_eth

Dear Evariste,

Thanks for such as quick reply and for producing the firmware - it is much appreciated.

I was using a DHCP server but have added the parameters to the USB_ETHERNET section of config,txt on the sdcard. (I am running the firmware from the sdcard)

On Linux I can disable (in the wired Connections menu in Gnome) the Analog Devices USB Network Ethernet Card emulation.

Using the Linux version of SDR++ I can use either IP or USB to receive - however for some reason the USB OTG has to be connected to the PC in use - if I replace the USB connection to the pc and supply just USB 5V from a PSU the Libresdr powers up but is not accessible from the IP address (no ping response).

I'm focussing on getting this working under Linux first - I'm very confused why I cannot access the Libresdr over the physical RJ45 Ethernet connection (192.168.0.116) when only providing 5V power to the Libresdr on USB OTG port.

I hope this makes sense - hopefully I am doing something stupid !

Thanks again,

James G1PVZ

Dear Evariste,

FIXED ! - I can now connect to the Libresdr via the ip address 192.168.118 via my network (DHCP) and direct from a laptop using manual configuration using the RJ45 Ethernet connector and supplying just power over the USB debug port.

I think the key point is to configure the [USB_ETHERNET] section in config.txt to the ip parameters for the physical RJ45 Ethernet port and leave the [NETWORK] as is (this appears to be the Analog Devices Ethernet over USB interface).

Hope this helps others.

Thanks for you help.

James
