what is EEPROMAnything.h used for? and when i type passwrd in, it doesn't reconize the function
You must search "ready", not "Ready" at line 81 of ESP8266.cpp.

hi
i am thanks for your help to peaple for publishin your good project
in this code i want give data from google Sheet and send data in telegram bot,
i use this project to give data from google sheet:
https://github.com/lorol/Googlesheet_DHT_simple
and use this project for recive and send data from telegram robat:
https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot
i use esp8266
i merge two above project but i cant compile because i give error , because two project use WiFiClientSecure.h library , and same client :(
i changed the client name , and code ha been compiled, but in serial monitor , program crashed
i changed "HTTPSRedirect* client= nullptr;" to "HTTPSRedirect* test= nullptr;" and change every client in the code to test,
i also change below code, in the next change
WiFiClientSecure client;
UniversalTelegramBot bot(BOTtoken, client);
to :
WiFiClientSecure test;
UniversalTelegramBot bot(BOTtoken, test);
and you can see my Serial monitor in both time:
Starting ...
Connecting to hooshmandsazan3

CPU Frequency: 80Mhz
Upload Using: SERIAL 115200
please help me please :(
The private method getIP() keeps writing into buf[ptr] even if ptr is > 15, so it goes out of the bounds of the array.
Just to let you know I created my own library here: https://github.com/Diaoul/arduino-ESP8266
It implements the full v0.20 AT command set and is non-blocking. I'll soon implement a derived client so I can pass it to the MQTT library.
Any help to improve the library is welcome :)
Are you planning to add MQTT and REST support to your library?
Which version of AT commands firmware of ESP this code support?
