Today I learned how to use a XBee as a standalone device, without an Arduino. This will be useful when building in 1:1 scale and needing to place sensors on a model that are spaced far apart. An Arduino is only needed at the coordinator XBee.
Also, I was able to successfully import the serial data from the XBee and bring it into a Grasshopper sketch by using Firefly components. The next step is to make sense of the data – currently it is garbled and showing as multiple varying values (see screenshot below). I’ve posted to the Firefly help forum in hopes of solving this, as processing the serial data from the XBee requires some code that is usually handled by the Arduino.
