Try Your First Scan

Confirm GhostESP is working with a passive Wi-Fi scan.

What this does

This first task passively lists nearby Wi-Fi access points. It does not connect to a network or transmit anything.

Before you start

  • GhostESP is flashed and powered on.
  • Use the on-device UI or a serial CLI connection. Do not run this scan from the WebUI on a single-board setup because the Wi-Fi radio is hosting GhostNet.
  • Attach the board’s supported Wi-Fi antenna if it has an external antenna connector.

On-device steps

  1. Open Menu → WiFi → Scanning.
  2. Choose Scan Access Points.
  3. Wait for the scan to complete.
  4. Choose List Access Points to review the results.

CLI steps

  1. Open the GhostESP serial terminal.
  2. Run scanap.
  3. Wait for the scan to finish.
  4. Run list -a to view the saved access-point list.

Expected result

GhostESP lists nearby networks with their name, channel, signal strength, and manufacturer when available. If no networks appear, move closer to a known access point and try again.

Troubleshooting

  • No networks found: Confirm the board supports Wi-Fi, attach its antenna if applicable, move closer to an access point, and scan again.
  • The scan stops immediately: Stop any active Wi-Fi task or portal, then retry.
  • The WebUI disconnects: Run Wi-Fi scans from the on-device UI or serial CLI, not from the WebUI on a single-board setup.
