Problem Remote patient monitoring wearables frequently suffer from excessive energy drain and unreliable Bluetooth reconnections.
Architecture Low-power Nordic nRF52/ESP32 wearable firmware pairing with a local SQLite cached cross-platform client app that syncs asynchronously with cloud storage.
What I built Designed the GATT profile structure, dynamic connection interval negotiation, and delta-compression algorithm for PPG/heart-rate streams.
Result TODO(owner): Confirm patient trial batch size. Achieved 7 days continuous battery operation on a 150mAh LiPo cell with zero recorded sample dropouts.
