Hi rudy, thanks so much for your replay. send my code for your.
i'm enable ESP in softAP+STA mode
so use of FS.H library for save my home-AP and ESP-AP SSID and PAS in ESP flash memory (SPIFFS), i make 2 function for this (GetEspApValue() & GethomeApValue()) user can be connect to ESP in AP mode so ESP can connect to any other AP in my code. but only can receive one user (client) message in same time.
please teach me how can solve my problem.
Code: Select all#include <ESP8266WiFi.h>
#include "FS.h"
//ESP SSDI AND PASS when config in softAP mode
char ESP_AP_SSID[20]= "*******";
char ESP_AP_PASS[20]= "*******";
//Home AP SSID AND PASS when ESP config in Station mode
char home_AP_SSID[20]= "*******";
char home_AP_PASS[20]= "*******";
WiFiServer server(8080);
void GetEspApValue(){
//espAP.text Save ESP/AP SSID AND PASS IF exsit read from if not exist create and write default SSID AND PASS
bool exist = SPIFFS.exists("/espAP.text");
if (exist){
File f = SPIFFS.open("/espAP.text", "r");
if (f){
for (int i=1; i<=2; i++){
String s=f.readStringUntil('\n');
if (i==1){
s.replace((0x0D),(0x00));
s.toCharArray(ESP_AP_SSID, 20);
}
if (i==2){
s.replace((0x0D),(0x00));
s.toCharArray(ESP_AP_PASS, 20);
}
}
f.close();
}
}
else{
File f = SPIFFS.open("/espAP.text", "w");
if (f){
f.println(ESP_AP_PASS);
f.println(ESP_AP_PASS);
}
f.close();
}
}
void GethomeApValue(){
//homeAP.text Save home/AP SSID AND PASS IF exsit read from if not exist create and write default SSID AND PASS
bool exist1 = SPIFFS.exists("/homeAP.text");

}
}
f.close();
}
