Researching XBee

This past week, I have been doing research on Xbee to see if it can perform asynchronous tasks. Asychronous (async) tasks allow us to send multiple requests to the transportation pod at once. These tasks are independent of each other and do not block one another. I want to see whether or not the Xbee controllers could only take one task at a time. If so, then our team would have to change components within our project architecture as a result of this limitation. Async is a difficult topic that requires a lot of research and information. As of late, I have been looking into JavaScript as the primary programming language to use for async programming. This language has built-in support for this type of task.
