# MQTT Mock Service

Simulates a service that:
- Subscribes to the ingest topic (server -> broker)
- Writes received messages to a local file (JSONL)
- Writes received messages to TDengine (super table)
- Forwards messages to another topic for downstream subscribers
- Optionally sends ack messages

Also includes:
- A random data sender (every 3 seconds by default)
- A simple subscriber that prints incoming payloads
- A WITS TCP sender for the Java TCP receiver

## Setup
```
python -m venv .venv
.\.venv\Scripts\activate
pip install -r requirements.txt
```

## Run (service mode)
```
python mqtt_mock.py --config config.yaml --mode listen
```

## Run (also publish test data)
```
python mqtt_mock.py --config config.yaml --mode both --interval 2
```

## Run random sender (3s interval)
```
python mqtt_sender.py --config config.yaml --interval 3
```

## Run subscriber
```
python mqtt_subscriber.py --config config.yaml
```

## Run WITS sender
Send one generated WITS packet to `wits.host/wits.port` or fallback `tms.server-ip/tms.server-port`:
```
python wits_sender.py --config config.yaml
```

Send packets continuously every 2 seconds:
```
python wits_sender.py --config config.yaml --interval 2 --count 0
```

Send a raw packet from file:
```
python wits_sender.py --config config.yaml --source-file data/wits_sample.txt
```

## Payload format (server -> broker)
```
