问题 There are Raspberry Pi 3 model B and MicroSD with NOOBS OS. Unfortunately I have not any display to get a direct access to NOOBS shell. So remote connection could be set via ssh. However my device does not have any IP-address. I read everywhere that the connection options must be set... via shell. But it's impossible for me!
