IP Addresses
Ignore this section if you’re not using WiFi.
We have made the assumption that you are using WiFi to connect to the Pi. This is our preference, but
it is by no means necessary. What may be confusing is that initially you have to use an Ethernet (wired)
connection to talk to the Pi. This is because the WiFi login information has not yet been programmed
into the Pi.
After you have set up WiFi (see Figure 7: WSPR Configuration Screen) you will have two valid IP
addresses assigned to the Pi. Either one will work. You probably wouldn’t have gone to the trouble of
setting up WiFi if you were just going to use Ethernet. So now is the time to remove the Ethernet cable.
Your Pi will now have one IP address. There is no advantage to having two IP addresses, so you should
remove the Ethernet cable if you’re planning on using WiFi.
WWoT Schematic
The WWoT schematic is shown in Figure 8: WWoT Schematic.
Congratulations! Connect an antenna and you're done.
