MR-1 Pro - set static IP address

Hello at DoreMIDI community

I have tried setting a static IP address in my DoreMIDI MR-1 Pro, but am not succeeding.

I am able to connect to the device when it is connected in my home network, but I want to be able to connect to it without a DHCP server in the network.

I have followed the instructions using MidiOx and am able to send the addressing Sysex message, but I don't get a confirmation response back from the device.

Is there something I am missing?

Are there more details you need from me to be able to assist?

Thank you.
