What I Built
- BLE scan and connection flow for discovering and pairing with the heat exchange device.
- Real-time data display for temperature/sensor readings streamed from the device.
- Control interface for sending commands back to the hardware.
- Public showcase repo (`heat-monitor-showcase`) explaining the architecture for portfolio purposes.
