Open-Source Contribution Update: Shell Over BLE
summary
PR is merged to upstream and implements a generalized BLE transport for Zephyr shell using Nordic UART-style service so the shell runs over BLE not just UART. Demo builds Blinky for an nRF52840 dev kit, flashes it, and shows console over BLE with a Python Bluetooth CLI on a Mac, sensor reads, LED control and deferred logging all working. It’s aimed at low‑throughput CLI use, supports multiple endpoints, and flags authentication and throughput limits.
