But I'm trying for a quicker, simpler solution here without having to get into an extra layer of C code just to get this one simple thing done. I know that I could just compile an EXE file to use as a stub program that will handle the necessary details of opening the COM port, sending the command, and closing the COM port. Or, the search results say to use COPY or ECHO, and of course, I tried that and it just makes a hard disk file named COM155. I do searches, and the results always talk about using PUTTY and typing things live. those just create a file on the hard disk called "COM155" when I try it. Is there a super-simple way to send these commands from the DOS prompt or from a DOS batch file or a vbscript? I've tried COPY and ECHO.

I have this all working, in that I can connect a serial terminal program to the COM155 port that the Arduino is connected to, and type the commands into the terminal program, and it will accept the commands and will work. I need to be able to run an automation script or batch file (on Windows XP and later only) that will switch the relays under certain conditions during an overnight test run. The program allows two telnet sessions to talk to each other, just like the ESP8266s do.I've got a piece of code running on an Arduino board that will accept ASCII text commands on its serial port, and then will switch some relays based on which text commands you send it. We tested it using a telnet program like Putty on Windows. It runs in a terminal window and reports all the activity as links are setup and removed.

You will have to install Python 2.7 on your computer to run this program. The code posted in this instructable is the version we used. Shaw has placed the code on a Github site and has updated it since the version here. After that anything one sends to the PC will be relayed to the others. 192.168.1.132:54321 and begin with sending the same string "for example, any ascii string". What the program does is let two or more ascii serial communicating devices log into the PC running the code. Our friend Shaw Terwilliger at Durham's Splatspace Maker Space wrote this very nice Python program that turns a PC into a relay for the ESP8266s, or any internet devices, to talk to each other fairly secuerly. The use of the MEGA or any Arduino with multiple Hardware Tx Rx ports makes this easy to do.Ī good example of this more complex approach is: Some folks reprogram the ESP8266 to go at slower speeds but that is a challenge for beginners. There are software serial libraries that will use other digital pins as Tx and Rx but they can have trouble going at the speed of the ESP8266. However, this is a little scary to do as you may make the Arduino unreachable from USB port for reprogramming, as the program will take over the programming port when it runs.

In a final product you could connect the ESP8266 to Tx and Rx on any Arduino like an UNO or low cost Pro Mini (make sure to get the pins right in the new code). This is a very straight forward approach. The code is for an Arduino Mega so that we could have two serial ports (Rx and Tx pins), one to program the Arduino and one for the Wifi (ESP8266). To glue the nunchuk to Wifi we used an Arduino.
