In researching different Bluetooth Profiles and Services for a class, I was very frustrated that I had to manually download a separate PDF for each Profile/Service listed on the official page. I realized that the UUID page for the various services at least had XML entires for the majority of the services. Since my goal was a simple table of services and the characteristics they offered, I figured I could automate parsing through these files, which I did with some quick python using requests to retrieve the pages and BeautifulSoup for parsing them.
GATT Characteristics are available in a similar table, so I modified my code to grab those also:
Here are the results, hopefully they’re useful to someone.
