RE: which firmware should be programmed on ESP8266 module ?
Thank you for your reply !!

I thought the firmware from https://www.espressif.com/ SDK AT bin should be programmed.
What if I already programmed a test arduino application ? Is the firmware still support the AT command ?

Right after purchasing ESP8266 module, tested with Arduino application. So, didn't know about the native firmware supporting AT commands set for TCP connection.
However, confirmed that NodeMCU V3 board which hasn't touched yet prints "ready" message on UART terminal and respond to "AT" command.

So, my last question is how I can restore the firmware of other ESP8266 module which already has Arduino test application. Espressif AT bin firmware is required ?

Thanks, NamKyu
