You must upload code while the TX led is lit. I do not understand step 5 of the flashing : Press the RST button while holding down the FLASH button on the breadboard - you should see a blue light on the Wi-Fi module and the TX led on the Arduino will light up.

In order to be able to change it and make it behave the way I like. Hello I am new to WiFi and UNO and I like to know how things work. The FLASH button connects the GPIO0 pin on the Wi-Fi module to ground. Note: the RST button connects the RST pin on the Wi-Fi module to ground. If the serial monitor is printing "." repeatedly, you have entered your WiFi information incorrectly. If the flash fails try the above steps again.
