== Configuration & Settings ==

Click '''Settings''' (gear icon) to configure the device. Settings are organized into tabs: '''Network''', '''Measurement''', '''Device''', and '''Email'''.

=== Main Controls ===

* '''Start:''' Begins a measurement session. The device runs an initialization phase (20–30 seconds) to prime the pump and stabilize the optical chamber. Data points appear after the "Sample Time" has elapsed.
* '''Stop:''' Ends the session and saves the file.
* '''Log Files:''' Opens the file manager to download or delete session logs.

=== Network Tab ===

Manages wireless connectivity. This is the default view when opening Settings.

|-
| '''WiFi''' || Scan for available networks, select a network, and enter a password. Use "Forget Network" to clear stored credentials and switch back to hotspot mode.
|-
| '''Hotspot Mode''' || Forces the device to create its own WiFi network, even if a known network is available.
|-
| '''Protect hotspot with WPA2 key''' || When enabled, secures the bcMeter hotspot with a custom password (minimum 8 characters) instead of the default.
|}

=== Measurement Tab ===

Controls how the device takes measurements. When Auto Flow Control (AFC) is active, an informational banner summarizes the current AFC configuration.

{| class="wikitable"
! Setting !! Description
|-
| '''Time between samples''' || '''Default: 300s (5 min).''' Adjustable from 30s to 1 hour. Ambient monitoring: 180–600s. Emission monitoring: 10–30s. Increasing frequency may increase noise.
|-
| '''Airflow per minute''' || '''Default: 100 mL.''' Adjustable 50–750 mL. Higher flow improves signal but loads filter faster. Disabled when Auto Flow Control is active.
|-
| '''Auto-adjust airflow''' || Automatically adjusts airflow based on measured BC concentration. When BC is high, flow is reduced to extend filter life; when BC is low, flow is increased for better signal.
|-
| '''Auto-start logging''' || Automatically begins measurement after device boot. Requires prior calibration. '''Power-loss recovery:''' If the device loses power during a measurement, it will automatically resume on next boot — regardless of this setting.

|-
| '''Device Name''' || Network hostname (e.g., bcmeter201). Sets the mDNS name — the device becomes reachable as <code>name.local</code> after renaming and rebooting.
|}

=== Email Tab (Notifications) ===

The bcMeter can send automated email notifications including periodic log delivery and filter status alerts. This requires an email service password (API key) — contact jd@bcmeter.org to request one.
