This guide explains the XBee ZigBee features and functions. Prior to Q1 2018, the XBee-PRO ZigBee S2 was used for both Waspmote v12 and Waspmote v15 product lines. Prior to July 2019, we commercialized the XBee ZigBee S2D for Waspmote v15 OEM. After this point, the XBee ZigBee 3 was integrated for our Waspmote v15 OEM and Plug & Sense! product lines. The library for this product did not experience great variations due to the module change.
