Using Arduino IDE for programming the ESP-12f

After the steps described in using-esp-12f-for-remote-control.html I decided to try to program the actual firmware using the Arduino IDE.  How to do this is described in many places e.g. esp8266-thing-hookup-guide/installing-the-esp8266-arduino-addon.

Use of GPI0

However I kept having failures when trying to upload the sketch. The reason was that to upload the firmware over serial I need to connect GPIO to ground rather than leaving it floating for actual running the saved firmware.

    ​ @Q26 I have flashed it just need minimum wiring to use it as UART, Can you share minimum wiring required to use ESP8266?
