Using an ESP8266 to Scan WiFi APs and Check Signal Strength (Percentage) with Arduino
This code is to use ESP8266, NodeMCU, Wemos D1 Mini to display all available access points (WiFi) on the serial monitor.
On this page, I have provided three different Arduino codes:
- Basic WiFi scan
- Display open WiFi only
- Advanced WiFi scan
Displays only access points that have no password. Displays the following:
- SSID
- Channel
- Signal strength in dBm
- Signal strength in percentage
- MAC address
- Encryption type
- Hidden or not
