Chapter 12 — Going Wireless with Wi-Fi 247

Testing It All

If you can ping and telnet to the WiMicro with its new IP address, remove the wall wart
power and plug in the Roomba prototyping plug. Then plug the assembly into the robot as
shown in Figure 12-11. The WiMicro Power LED should light as soon as you plug it into the
robot and within a few seconds it should be ping-able again. Turn on Roomba by pressing the
Power button, and start sending ROI commands to it through port 10001 of the WiMicro.

As in the previous chapter, you can use the roombacomm.net.SimpleTest program to test
Roomba. All the roombacomm.net API will work with a Wi-Fi Roomba as well as it does
with an Ethernet Roomba. In fact, try out roombacomm.net.SimpleTest now. From the
settings used above, invoking the test program would look like this:
demo% cd roombacomm
demo% ./runit.sh roombacomm.net.SimpleTest 192.168.0.90:10001
