Explore a high-performance and highly configurable Bluetooth Low Energy 4.2 stack in this 41-minute conference talk. Dive into Apache Mynewt's NimBLE, the world's first fully open source BLE stack for both host and controller subsystems in MCU environments. Learn about its granular configuration options, including number of slots per connection, max concurrent connections, and multiple advertising instances. Discover how NimBLE's flexibility enables various use cases, such as 32+ concurrent connections on Nordic nRF52 chips, large data bursts with multiple peripherals, and peripheral-to-multiple-central connections. Understand how the stack's design allows for size reduction in resource-limited environments. Gain insights into Silver Spring Networks, open source benefits, configuration files, code size, supported platforms, controller and host details, and access to comprehensive documentation.
