Eclipse IDE for C/C++ Developers
Version: 2018-09 (4.9.0)
Build id: 20180917-1800
OS: Windows 7, v.6.1, x86_64 / win32
Java version: 1.8.0_191
As System is working with arduino boards I added ESP8266
This is an old sketch used as test ESP8266
This sketch is working with no propbem using arduino Ide. It is scaning the net and send the result on a LCD display
include <Arduino.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <ESP8266WiFi.h>
#define I2C_ADDR 0x27 // <<- Add your address here.
#define Rs_pin 0
#define Rw_pin 1
#define En_pin 2
#define BACKLIGHT_PIN 3
#define D4_pin 4
#define D5_pin 5
#define D6_pin 6
#define D7_pin 7
LiquidCrystal_I2C lcd(I2C_ADDR, En_pin, Rw_pin, Rs_pin, D4_pin, D5_pin, D6_pin,
D7_pin);
void setup() {
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
lcd.begin(16, 4, LCD_5x10DOTS); // LCD 16x4
// LCD Backlight ON
lcd.setBacklightPin(BACKLIGHT_PIN, POSITIVE);
lcd.setBacklight(HIGH); // accende Bachkight
}
void loop() {
int n = WiFi.scanNetworks();
if (n == 0) {
lcd.setCursor(0, 0);
lcd.print("no networks found"); // Start Print text to Line 1
lcd.setCursor(0, 1);
lcd.print("--------"); // Start Print Test to Line 2
}
else {
lcd.setCursor(0, 0);
lcd.print(n);
lcd.setCursor(0, 1);
lcd.print(" networks found ");
delay(2000);
for (int i = 0; i < n; ++i) {
// Print SSID and RSSI for each network found
lcd.setCursor(0, 0);
lcd.print(" "); // clr line 1
lcd.setCursor(0, 0);
lcd.print(i + 1);
lcd.print(": ");
lcd.setCursor(0, 1);
lcd.print(" "); // clr line 2
lcd.setCursor(0, 1);
lcd.print(WiFi.SSID(i)); // HERE IS THE ERROR
delay(2000);
}
}
when i compile I have such an output:
