I am using the KW41Z module with the 802.15.4 library. I need to use wireless security with multiple end devices where each end device will use an unique key. I am currently trying to figure out how I need to configure the PIB values for this. The demo application only supports a single end device so it is useful but not 100%. I am in the process of reading through AN4973 but I am having a hard time finding definitions for the different PIB variables in order to set multiple keys, and the document seems to use the same key for multiple devices. Any advice?
