ESP8266 SPIFFS JSON SoftAP MQTT Store (wifi Station, mqtt server and mqtt port)

ESP8266 SPIFFS JSON SoftAP MQTT Store (wifi Station, mqtt server and mqtt port) ESP8266 Arduino sketch including soft access point option and mqtt server information store to a json file (this is like Wifimanager by tzapu) but i need fresh embedded code so you should use below library only #include <FS.h> #include <ESP8266WiFi.h> //esp8266/Arduino #include <ESP8266WebServer.h> //esp8266/Arduino #include <WiFiClient.h> #include <ArduinoJson.h> //bblanchon/ArduinoJson #include <PubSubClient.h> //knolleary/pubsubclient When Trigger GPIO D0 Like #define AP_PIN D0 // GPIO D0 /// PRESS BUTTON // softAPConfig will start [login to view URL](AP, 12345678, channel, hidden, max_connection) [-- ([login to view URL](ssid, password, 1, 1) (Will hide SoftAP SSID) SoftAP IP address = [login to view URL] --] Browser input field on webpage will (follow attached image) --wifi ssid-- --wifi password-- --mqtt server-- --mqtt port-- ==Save== Save data to Json file "/[login to view URL]" like below { "ssid":"myrouterssid" "Password":"12345678" "mqtt_server":"[login to view URL]", "mqtt_port":"1883" } Will save credential make a url like [login to view URL] After save data to esp show successful message When ESP Start information load from "/[login to view URL]" and connect to wifi and mqtt server automatically If i need to change wifi or mqtt server then press 1 GPIO PIN High and softAPConfig will start for 60 second if no change then esp restart and previous data load from "/[login to view URL]" file I have a sketch you should also include in your sketch Please see attached file
