If you like to connect from your Windows environment to your newly ESP8266 ESP-Link, you may use the very good software from Tibbo to create a virtual serial port.
Download the version corresponding to your system (x32 or x64).
Install the package.
Open Tibbo VSP Manager and Add a port
Set the properties of the port as following to creat a TCP connection to the ESP8266 flashed with ESP-Link. The IP at the bottom is the IP address of the ESP82266!
Once done, a virtual port will be created in the COM section of the Device Manager.
For testing, use the serial console of Arduino IDE. (One of my temperature logger is sending data through the ESP8266).
From the console of the ESP-Link
I don’t know if it is possible to use the serial port to program an arduino that way but I know that the control lines could be changed from the setting. Let’s see, I will give it a try later.
