I am using ESP-12E with Arduino using hardware serial communication(i.e RX & TX) and accepts the SSID and the password in the server mode. But with ESP on Hardware Serial, when I include the SoftwareSerial.h to communicate with another microcontroller with it, ESP-12E doesn't accept the SSID and the password in the server mode. Tried the same with ESP01 as well; problem persists. In my program, I am using the libraries like Wire.h,EEPROM.h, and local RTClib.h along with SoftwareSerial.h.
FYI, have tried with several pins like 4,5, 8,9 etc. Result is the same. Baud rate is set at 4800 for SoftwareSerial.
