nRF54L15 Secure Smart Lock

Build a next-generation secure smart lock with the nRF54L15 — CRACEN hardware crypto for secure BLE key management, tamper detection peripherals, and years of battery life on 2xAA cells.

Build a next-generation secure smart lock with the nRF54L15 — CRACEN hardware crypto for secure BLE key management, tamper detection peripherals, and years of battery life on 2xAA cells.

Why This Combination

The nRF54L15's CRACEN security engine handles elliptic-curve key generation and BLE LESC pairing entirely in hardware, eliminating software crypto vulnerabilities in access control applications.

What FirmwareMaestro Generates

For this solution, FirmwareMaestro produces a complete project package:

  • Product Requirements (PRD)
  • Firmware Architecture
  • Hardware Abstraction Layer (HAL) design
  • State Machine specification
  • Code Scaffold (main.c, prj.conf, CMakeLists.txt, Kconfig)
  • Devicetree overlay for the target board
  • AI-pair-programming .cursorrules
  • Build and flash instructions

See the Code Scaffolds guide for details.
