Hey. I am new to ESP8266 wifi module. My end goal is to be able to control a remote Xbee devices that is connected to Arduino. To control a device I would have to connect a relay and set a digital pins to high to turn on relay.
First of all, I want to do an ESP excersise to just simply control LED through a web server that is connected directly to one of the Arduino digital pins. I did some research and found that in order to use ESP8266 , it must be flashed. I have an FTDI serial to USB adapter that I am planning to use to flash my ESP8266.
https://www.iot-experiments.com/flashing-esp8266-esp01/. I use this website as A guide. So in order to flash ESP module, GPIO pin should be low, while the module is reseting.
There is one thing that I do not understand. What does 'flashing' actually mean? Do I just do it once or everytime I want to upload a new code?
Can i upload a code to my ESP8266 after I flash it with my ftdi adapter?
