Overview
What this challenge is about.
Build a Zephyr-Based Sensor Node for Industrial IoT. Advanced challenge in code. Writing production code that solves real engineering problems, earn a blockc...
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.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
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
