Overview
What this challenge is about.
Build Zephyr firmware for nRF52840 with SPI accelerometer, FFT, and BLE. Validate at under 20 µA. Deliver code and report to earn your verifiable certificate.
The scenario
The vendor (around EUR 320M revenue, supplying Tier-1 automotive plants) wants their first software-defined sensor product to be field-upgradable and the firmware team has 6 months to MVP.
The Brief
What you'll do, and what you'll demonstrate.
Implement a Zephyr-based wireless vibration sensor that samples at 4 kHz, performs on-device FFT, transmits over BLE every 30 seconds, and meets a 3-year coin-cell battery target.
Earning criteria — what you'll demonstrate
- Configure Zephyr device-tree and Kconfig for a custom sensor board
- Implement BLE GATT services with throughput + power tradeoffs
- Profile and tune for sub-20-microamp average current
- Apply on-device DSP under tight memory and energy budgets
