Add WiFi mesh handoff infrastructure: WiFiState.msg interface: - SSID, signal strength (dBm), connection status - AP address, frequency, link quality - TX/RX rates, roaming flag - Available APs for handoff decision WiFi Monitor Node: - Signal monitoring via iwconfig/nmcli - Auto-roam at -70dBm threshold - Seamless wpa_supplicant roaming - Gateway ping (8.8.8.8) every 5s - USB tethering fallback if offline >30s - TTS warnings for connectivity issues - Coverage logging with AP transitions Features: - Configurable roaming threshold (-70dBm default) - Gateway connectivity verification - Offline detection with configurable timeout - USB tethering auto-activation/deactivation - Signal strength change logging (>5dBm) - AP transition logging - Manual rescan/tether control commands Topics: - /saltybot/wifi_state (String) - /saltybot/speech_text (String warnings) - /saltybot/wifi_cmd (String commands) Configuration: - interface: wlan0 - roam_threshold_dbm: -70 - offline_warning_timeout: 30.0 - target_ssid: SaltyLab - fallback_tether: true - coverage_log_file: /tmp/wifi_coverage.log Roaming Behavior: - Monitors signal continuously - When signal < -70dBm, scans for stronger AP - wpa_supplicant performs seamless handoff - Logs all AP transitions to coverage file Fallback Behavior: - Pings gateway every 5 seconds - If unreachable for >30s, activates USB tether - TTS alert: 'Warning: Lost WiFi connectivity...' - Auto-deactivates when WiFi restored Coverage Mapping: - Logs timestamp, SSID, signal, connected status - Tracks roaming events - Useful for mesh network optimization Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
