+# Using Bluetooth Low Energy for Good
+
+When you hear Bluetooth, you probably think of annoying consumer tech like awkward hands-free phone guy, wow so fitness: you-took-1,337-steps-today trackers, and stalking customers with ads in retail stores. But, I propose that Bluetooth LE can be used for good, and has many potential useful and interesting applications.
+
+I plan to cover the basic high-level concepts of Bluetooth LE such as scanning and advertising, services, characteristics, and peripheral and central networking. I'll include code examples using the `noble`/`bleno` nodejs modules and briefly touch on firmware and hardware aspects of development.
+
+The talk will conclude with examples of how low cost, low power bluetooth radios can be used to interface with distributed systems in meatspace and facilitate more secure cryptographic transactions.
