Confirm GhostESP is working with a passive Wi-Fi scan

On this page

This first task passively lists nearby Wi-Fi access points without connecting to a network or transmitting anything. Run it from the on-device UI or a serial CLI, not the WebUI on a single-board setup, where the Wi-Fi radio is already hosting GhostNet. Attach the board’s supported Wi-Fi antenna if it has an external antenna connector.

On-device

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

CLI

  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.

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.
