## Reporter node's features
|
||
|
||
### Captive Portal Configuration:
|
||
|
||
- Uses WiFiManager to allow a user to configure the Wi‑Fi credentials, API server URL, and scanning delay via a captive portal.
|
||
- A configuration mode is triggered automatically if no valid configuration is available or by user intervention via a dedicated button.
|
||
|
||
### BLE Scanning:
|
||
|
||
- Scans for BLE devices advertising a specific service UUID.
|
||
- Collects all sensor BLE addresses over a fixed scan period.
|
||
|
||
### Sequential Sensor Processing:
|
||
|
||
- Processes each discovered sensor one-by-one.
|
||
- For each sensor, the node:
|
||
1) Connects to the sensor via its BLE address.
|
||
2) Reads the sensor value from a characteristic.
|
||
3) Disconnects from the sensor.
|
||
|
||
### API Reporting:
|
||
|
||
- Constructs a JSON payload with the sensor’s BLE address as the device identifier, along with the measured moisture value.
|
||
- The payload is formatted according to a flattened model (including fields such as "deviceId", "moistureLevel", and a nested "device" object with "deviceId" and "nickname").
|
||
- Sends the payload via an HTTP POST request to your configured API endpoint.
|
||
|
||
### Configurable Scan Delay:
|
||
|
||
- Uses a user-configurable delay (default 30 seconds) between scan cycles so that after processing sensors, the node waits before scanning again.
|
||
|
||
### Robust Error Handling & State Management:
|
||
|
||
- Employs a simple state machine to manage scanning, connecting, and waiting phases.
|
||
- Includes duplicate filtering so the same sensor isn’t processed multiple times in one cycle.
|
||
- Provides conditional debug logging to aid in troubleshooting and can be disabled for production builds.
|
||
|
||
### Watchdog Integration:
|
||
|
||
- Uses built-in ESP32 Wachdog methods to ensure continued device operation. |
