Known Engineering Constraints & Bench Boundaries
All projects are built from real bench testing and validated by automated static analysis and continuous integration. Note the following operational boundaries:
- MAX30102 PPG signal accuracy requires firm mechanical contact against the wrist surface.
- GPS cold start requires open-sky reception for 30-45 seconds.
- NimBLE stack optimizes RAM footprint to fit within ESP32-C3 internal SRAM.
