Test distance measurements

1. Connect and turn on a Cricket configured as a listener to your host.

2. Turn on a Cricket configured as a beacon.

3. You should now see distance measurements appear in your terminal every time the listener hears from the beacon. The output has many fields; the ``DB'' field gives the distance to the beacon. The default units are centimeters (but can be changed to inches); the next chapter documents these and other options in detail.

If the above steps work, you can now use your Crickets to write and run applications! If the steps don't work, you may find the troubleshooting hints in the next chapter useful.
