# HiLink LTE Modem

Control Huawei HiLink USB LTE modems via their local REST API.

## Setup

The modem must be in **HiLink mode** (not stick/serial mode) and accessible via HTTP.

### Config

Set gateway IP in `~/.config/hilink/config`:
```bash
HILINK_GATEWAY=192.168.200.1
```

Or pass via environment: `export HILINK_GATEWAY=192.168.200.1`

Default: `192.168.200.1`

### Network Requirements

The LTE USB interface needs an IP on the modem's subnet (e.g., 192.168.200.x). Configure as **static IP with no gateway and no DNS** to avoid routing conflicts:

```
# /etc/network/interfaces.d/lte
allow-hotplug lte0
iface lte0 inet static
    address 192.168.200.100/24
```

**Critical:** Never let the LTE interface set a default route or DNS — it will override your LAN connection. Use `nogateway` and `nohook resolv.conf` in dhcpcd, or a static config with no gateway line.

### Persistent Interface Name

USB network interfaces get random names on each boot. Create a udev rule for a stable name:

```bash
# Find MAC address
cat /sys/class/net/enx*/address

# Create udev rule
echo 'SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="xx:xx:xx:xx:xx:xx", NAME="lte0"' \
  | sudo tee /etc/udev/rules.d/70-lte-modem.rules
```

## CLI Usage

```bash
# SMS
scripts/hilink.sh sms send "+41791234567" "Hello!"
scripts/hilink.sh sms list
scripts/hilink.sh sms read 40001
scripts/hilink.sh sms delete 40001

# Status & Signal
scripts/hilink.sh status
scripts/hilink.sh signal

# SIM PIN
scripts/hilink.sh pin enter 1234
scripts/hilink.sh pin disable 1234
scripts/hilink.sh pin status

# Prepaid Balance (USSD)
scripts/hilink.sh balance

# Connection info
scripts/hilink.sh info
```

## API Overview

All HiLink API calls require a session token + CSRF token pair:

```bash
# Get tokens
curl -s http://GATEWAY/api/webserver/SesTokInfo
# Returns: <SesInfo>cookie</SesInfo><TokInfo>csrf_token</TokInfo>

# Use in requests
curl -X POST http://GATEWAY/api/endpoint \
  -H "Cookie: <SesInfo value>" \
  -H "__RequestVerificationToken: <TokInfo value>" \
  -H "Content-Type: application/xml" \
  -d '<xml request body>'
```

For detailed API endpoints, see [references/api.md](references/api.md).

## Troubleshooting

- **Error 113018 on SMS send**: SIM not registered to network. Check PIN status and signal.
- **SimState 260**: PIN required. Enter PIN first via `scripts/hilink.sh pin enter <PIN>`.
- **SignalStrength 0**: No network registration. Wait after PIN entry or check antenna.
- **DNS/routing broken**: LTE interface set a default route. Remove it: `sudo ip route del default via 192.168.200.1`
- **Interface name changed**: USB MAC randomized. Create udev rule (see Setup).

Workflow & Productivity

Meeting Prep

3891

from openclaw/skills

Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.
