feat: WiFi mesh handoff - seamless AP roaming (Issue #458)
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>

# SaltyBot WiFi Mesh Handoff (Issue #458)
|
||||||
|
|
||||||
|
Seamless WiFi AP roaming with automatic fallback to USB tethering.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- **Signal Monitoring**: Continuous WiFi signal strength tracking via iwconfig
|
||||||
|
- **Auto-Roaming**: Seamless handoff to stronger AP when signal < -70dBm
|
||||||
|
- **Gateway Ping**: Periodic connectivity verification to 8.8.8.8
|
||||||
|
- **USB Tethering Fallback**: Auto-activate phone USB tether if WiFi offline >30s
|
||||||
|
- **TTS Warnings**: Voice alerts for connectivity issues
|
||||||
|
- **Coverage Mapping**: Logs all signal transitions for analysis
|
||||||
|
- **wpa_supplicant Integration**: Native WiFi roaming support
|
||||||
|
- **Status Publishing**: Real-time WiFi state on `/saltybot/wifi_state`
|
||||||
|
|
||||||
|
## Setup
|
||||||
|
|
||||||
|
### 1. WiFi Configuration
|
||||||
|
|
||||||
|
Edit `/etc/wpa_supplicant/wpa_supplicant.conf`:
|
||||||
|
|
||||||
|
```
|
||||||
|
network={
|
||||||
|
ssid="SaltyLab"
|
||||||
|
psk="password"
|
||||||
|
bgscan="simple:30:-70:600"
|
||||||
|
ap_scan=1
|
||||||
|
priority=10
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Launch
|
||||||
|
|
||||||
|
```bash
|
||||||
|
ros2 launch saltybot_wifi_monitor wifi_monitor.launch.py
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Monitor
|
||||||
|
|
||||||
|
```bash
|
||||||
|
ros2 topic echo /saltybot/wifi_state
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
| Parameter | Default | Description |
|
||||||
|
|-----------|---------|-------------|
|
||||||
|
| `interface` | wlan0 | WiFi interface |
|
||||||
|
| `roam_threshold_dbm` | -70 | Roaming signal threshold |
|
||||||
|
| `offline_warning_timeout` | 30.0 | Timeout before USB fallback |
|
||||||
|
| `target_ssid` | SaltyLab | Target mesh SSID |
|
||||||
|
| `fallback_tether` | true | Enable USB tethering |
|
||||||
|
|
||||||
|
## Roaming Behavior
|
||||||
|
|
||||||
|
Automatic roaming when:
|
||||||
|
1. Signal < -70dBm
|
||||||
|
2. Stronger AP available (>5dBm better)
|
||||||
|
3. wpa_supplicant performs seamless handoff
|
||||||
|
4. No ROS message disruption
|
||||||
|
|
||||||
|
## Fallback Behavior
|
||||||
|
|
||||||
|
Automatic fallback when:
|
||||||
|
1. Gateway ping fails for >30 seconds
|
||||||
|
2. TTS warning published
|
||||||
|
3. USB tethering activated
|
||||||
|
4. Auto-deactivated when WiFi restored
|
||||||
|
|
||||||
|
## Topics
|
||||||
|
|
||||||
|
| Topic | Type | Description |
|
||||||
|
|-------|------|-------------|
|
||||||
|
| `/saltybot/wifi_state` | String | Current WiFi state |
|
||||||
|
| `/saltybot/speech_text` | String | TTS warnings |
|
||||||
|
| `/saltybot/wifi_cmd` | String | Control commands |
|
||||||
|
|
||||||
|
## Coverage Log
|
||||||
|
|
||||||
|
```bash
|
||||||
|
tail -f /tmp/wifi_coverage.log
|
||||||
|
```
|
||||||
|
|
||||||
|
Output:
|
||||||
|
```
|
||||||
|
2026-03-05T09:15:23.456 | SSID:SaltyLab | Signal:-65dBm | Connected:true | Roaming:false
|
||||||
|
2026-03-05T09:15:45.789 | SSID:SaltyLab-5G | Signal:-62dBm | Connected:true | Roaming:true
|
||||||
|
```
|
||||||
|
|
||||||
|
