Hello, I have an old robot (like a rover). for programming the robot there is a software for making the codes and then it transfers the code to robot using serial port, the serial cable has only 2 wires on the end which connects to robot. as my laptop doesn't have serial port I was looking for a way to send these codes to robot. I found that connecting RESET to GND can help somehow doing this but as I'm not so good in computers I don't know exactly how to upload my simple code to my robot using my ESP8266 Module.
link to the description of your robot?
A picture of the cable and the connector?
What type of code upload?
anything more than what you posted could probably help someone help you...
any link ? "roboro" does not return much... probably something defunct... would be interesting to first listen to whatever the "programmer" sends to translate the program into orders
Have you tried a USB to RS232 converter cable?
