Have you really figured out a way to remotely program your esp8266 using the Arduino IDE? If so, do you have more detailed information to go about this?

Where do we need to setup ESP IP in arduino IDE?

Hi I have the same question as bkrajendra.. how to setup adress of esp in IDE.. So far I have modified espota.py directly.. but is annoying to rewrite it for each ESP module.. thx..

@bkrajendra : in arduino IDE -> Tools > port. Your esp should appear in this section under "network ports". But I doesn't upload for me
(sorry if bad englsih, I'm french)

To specify IP instead of serial port (in case it does not appear in the list):
File > Prefrences will show your preferences file
C:\Users\AppData\Roaming\Arduino\preferences.txt
Edit with IP of esp module, for example :
serial.port=192.168.0.50
Restart Arduino and check bottom-right corner to see your IP is displayed
