# SNIFFER

> Use SNIFFER to inspect Wi-Fi activity and save PCAP files.

Use `SNIFFER` to view packets, interference-related signals, and devices looking for Wi-Fi, or to save data as PCAP files.

<Info>
  This page presents observations for inspection; finding a device does not mean it is a threat. Always compare results with the real environment.
</Info>

## 🧭 Choose a tool

| Menu             | Use when you need to…                               |
| ---------------- | --------------------------------------------------- |
| `Packet Monitor` | View or save packets by type.                       |
| `Jammer Detect`  | Observe anomalies that may relate to interference.  |
| `Find Hidden AP` | Look for APs that do not normally advertise a name. |
| `WiFi Tracker`   | Track detected AP information.                      |
| `STA Tracker`    | Track detected client-device information.           |

Choose `Packet Monitor` to view or save packets. Use another tool when you need a specific observation or tracker.

## 📦 Packet Monitor

```text theme={"theme":{"light":"github-light","dark":"dracula"}}
WIFI → SNIFFER → Packet Monitor
```

<AccordionGroup>
  <Accordion title="View all packets" icon="list-filter">
    `Monitor All` displays all detected packets without saving a file.
  </Accordion>

  <Accordion title="View and save" icon="save">
    `All + Save` displays packets and saves a PCAP file. Check available space first in [FILES → File Explorer](/en/features/files#file-explorer).
  </Accordion>

  <Accordion title="Filter by type" icon="filter">
    Choose `Deauth`, `Beacon`, `Probe`, `Auth`, `Client`, `EAPOL`, or `Action Monitor` to view that packet type only.
  </Accordion>
</AccordionGroup>

<Info>
  📷 **Image to add:** Packet Monitor with arrows pointing to packet count, channel, and save status.

## 💾 Save a PCAP step by step

<Steps>
  <Step title="Check free space">
    Open `FILES → File Explorer`. For extended recording, insert a supported microSD card first.
  </Step>

  <Step title="Start saving">
    Open `WIFI → SNIFFER → Packet Monitor → All + Save`.
  </Step>

  <Step title="Collect data">
    Let the device run only for the needed period. Do not capture data from networks without authorization.
  </Step>

  <Step title="Stop and check the file">
    Hold the center button for about one second, then open `FILES → File Explorer` to check the created file.
  </Step>
</Steps>

## 📍 Trackers and other detectors

* `Jammer Detect` is an observation aid only; an alert does not always confirm a jammer.
* `Find Hidden AP` looks for APs with hidden names; results depend on packets observed at the time.
* `WiFi Tracker` tracks APs.
* `STA Tracker` tracks client devices.

<Info>
  🎬 **Media to add:** A clip of up to 30 seconds showing Jammer Detect, Find Hidden AP, WiFi Tracker, and STA Tracker, noting that results can vary by location.
