Open Source Bluetooth Device Firmware for IoT and Makers
summary
An open source link‑layer and firmware for Nordic nRF51/nRF52 chips exposes HCI over UART so Linux BlueZ or Zephyr hosts attach to an Arduino 101 or nRF51 dongle as a normal BLE controller. The build uses Mynewt/Zephyr toolchains, supports 4.2 secure connections, privacy and larger MTUs, produces BT‑snoop traces decoded by btmon/Wireshark, and runs in demos on Arduino 101 and Linux. The firmware is flashable, upstreamed, and functions for testing and qualification.
