I thought I would follow up on my question below in the event any newbies like me search for this in the future.
So the answer to my question is, yes I need to create my own driver. There are two guides I am going to use..... http://www.weewx.com/docs/customizing.htm#porting and......an existing bluetooth driver that was referenced above (same link is here for convenience: https://github.com/daduke/ventusw820) I'll play around with the directions for creating my own and follow up on the post if I find success.
