新建的源代码中输入扫描WiFi的程序代码如下:
#include "ESP8266WiFi.h"void setup() { Serial.begin(115200); // Set WiFi to station mode and disconnect from an AP if it was previously connected WiFi.mode(WIFI_STA); WiFi.disconnect(); delay(100); Serial.println("Setup done");}void loop() { Serial.println("scan start"); // WiFi.scanNetworks will return the number of networks found int n = WiFi.scanNetworks(); Serial.println("scan done"); if (n == 0) Serial.println("no networks found"); else { Serial.print(n); Serial.println(" networks found"); for (int i = 0; i < n; ++i) { // Print SSID and RSSI for each network found Serial.print(i + 1); Serial.print(": "); Serial.print(WiFi.SSID(i)); Serial.print(" ("); Serial.print(WiFi.RSSI(i)); Serial.print(")"); Serial.println((WiFi.encryptionType(i) == ENC_TYPE_NONE)?" ":"*"); delay(10); } } Serial.println(""); // Wait a bit before scanning again delay(5000);}然后在菜单栏选Build
