Why This Project Is Awesome

Which criterion does it meet? (pick one)

• Industry Standard - The go-to tool for a specific use case
• Rising Star - 5,000+ stars in <2 years, significant adoption
• Hidden Gem - Exceptional quality, solves niche problems elegantly

Explain:
I have added multiple links to this single PR since this adds a new section entirely. I call these as hidden gems since each of the project solves niche use cases. Few projects might have similar functionality, but different in nature.

How It Differs

• Bleak: standalone library for BLE in python.
• SimplePyBLE: Python binding for SimpleBLE framework.
• pygatt: Python wrapper for GATT and BGAPI.
• bless: A BLE server library.
• bumble: A bluetooth stack written in python.
• QtBluetooth: python binding for QtBluetooth from Qt GUI framework.

I worked on a Bluetooth application, we wanted to ship a product pretty fast so it was done with python, and the above is the cream of the crop of my research.

@vinta So, this is how I can think of doing PRs with singular link, I will clone the master branch, will add the section to it in my branch. Then for adding the projects individually, I will clone my branch which adds the section.

That works right.

Thanks for the suggestion! Rather than a full Bluetooth section, we think bleak (the most popular BLE library) would fit well under the existing Hardware section. Would you be open to submitting a single PR adding just bleak there?
