So I'm trying to send a string of data to Arduino using CommMG UDF. It seems that Arduino is not receiving it. I used Device Monitoring Studio and it shows that the data is sent fine and looks exactly the same as if I sent it from Arduino Serial Monitor. Is CommMG compatible with USB?

Global $CMPort = 9
Global $CmBoBaud = 9600
Global $sportSetError = ''
Global $CmboDataBits = 8
Global $CmBoParity = "none"
Global $CmBoStop = 1
Global $setflow = 2

_CommSetPort($CMPort, $sportSetError, $CmBoBaud, $CmboDataBits, $CmBoParity, $CmBoStop, $setflow)

If @error Then
    MsgBox(16,"Error!","Can't connect to Arduino on port - "&$CMPort)
    Exit
EndIf

_CommSetRTS(0)
_CommSetDTR(0)

_CommSendString("x" & 128 & "y" & 256 & "e", 1)

It should be.  I've used it and seen it used for other "Arduino" serial comm.

Does the _CommListPorts function display the port you are trying to connect to?

Yes. But now it started to work. I don't know what happened.

      I have a autoit exe file which is used in upload/browse file functionality.  This has been integrated with selenium framework and I am invoking the autoit exe using Java process and runtime. 
      Now the issue is when I run the scripts and invoke the autoit exe in local it works perfectly.  But when I use selenium grid or jenkins to run the scripts in another windows server it is not working.
      Can anyone please suggest any solution for this?

      Hello, the script below will read column A from an excel file - and if a value matches in the browser, it will click the corresponding link and click on a specific button to paste the data, then writes "Completed" in Column B. It will continue to read from the excel file and do the same thing for all the remaining rows.

      What i am trying figure out now is if the excel crashes while the script/loop is running, I want to relaunch the excel file continue to the last row before the excel crashed. So if the value of column B is not marked as "completed", it should continue from that row
      Appreciate any help that I can get to achieve this.

      Computer Plucker is a fork and a "restoration" of Computer stats utility by @Rogue5099 (link)
      You can obtain various data about local machine, as from the screenshot.

      But my goal is not (only) to provide another PC stats tool, but to develop a very basic remote inventory tool, like (a small subset of) the abandoned Spiceworks or the Microsoft SCCM.
      So this script can be deployed on a machine as a standalone executable (yes you need only ONE file to distribute) , and launching the .EXE it installs itself to a folder (es. c:\autoit\computerplucker)
      In tools menù you can set two tasks and not only
      one for creating every week a file.ini with all the data of the machine. another one  for creating every week a file.ini with all the data of the machine PLUS uploading a CRYPTED record of the machine in a free mysql DB online For my needs, I am  deploying the .exe and schedule the second task, uploading data one time a week.
      In tools menù you will find also commands for:
      manual creating the .ini data file  to upload the data in crypted records to upload the data in clear text records (for testing..) total uninstall of ComputerPlucker, with a simple security code. many other tasks in not so logical order.. next version I have to tidy the menù... So my plan is to deploy this on my machines, and have the data in a online DB, this DB will be for me only a "cache" for data records to be downloaded (and deleted) by another script.
      As today the account of this TEST DB is embedded in code, using the "File to Base64 String' Code Generator" by @UEZ (used also for embedding icons and XML task definitions)
          Local $mysqlhost = "sql11.freemysqlhosting.net"
          Local $mysqlport = "3306"
          Local $mysqldb = "sql11403701"
          Local $mysqluser = "sql11403701"
          Local $mysqlpsw = "QtL7T9U5GV"
      The DB is one table of 30 mysql tinytext fields... very simple indeed...
      You can try to upload data to this DB and access (phpmyadmin or a random mysql browser app) to see the results.
      Or you can use my ComputerPluckerDBbrowser (see at the end of this post) a script to collect and manage the data.

      PRIVACY warning: you are uploading data of your PC account and PC data, test as your risk (or test in another account...)
       
      I also created a small post in a blog for not so geek friends, and I have a more advanced version of the data browser, you can have more info lookin' here. 😀
      Attached you will find the code, and all the necessary includes are at this >link<.
      ComputerPlucker.EXE is downloadable >HERE<
      ComputerPluckerDBbrowser.EXE is downloadable >HERE<

      Hello ,
      I am trying to use Websockets in AutoIt.
      It is to fetch live stock market prices , API is provided and documentation available for python language.
      The link for the code snippet is :
      https://symphonyfintech.com/xts-market-data-front-end-api-v2/#tag/Introduction
      https://symphonyfintech.com/xts-market-data-front-end-api-v2/#tag/Instruments/paths/~1instruments~1subscription/post
       
      https://github.com/symphonyfintech/xts-pythonclient-api-sdk
       
      Second Link is to subscribe to a list of ExchangeInstruments.
      Now I would like to get live stock ltp (LastTradedPrice) for a few stocks whose "ExchangeInstrumentID" I know.
      I am able to use the WinHttp object to perform actions using simple codes like below :
      I have the secretKey and appkey and can generate the needed token. And get the unique ExchangeInstrumentID.

      Below code is just for example of how I am using WinHttp. Unrelated to socket part.
      Global $InteractiveAPItoken = IniRead(@ScriptDir & "\Config.ini", "token", "InteractiveAPItoken", "NA") $baseurl = "https://brokerlink.com/interactive/" $functionurl = "orders" $oHTTP = ObjCreate("winhttp.winhttprequest.5.1") $oHTTP.Open("POST", $baseurl & $functionurl, False) $oHTTP.SetRequestHeader("Content-Type", "application/json;charset=UTF-8") $oHTTP.SetRequestHeader("authorization", $InteractiveAPItoken) $pD = '{ "exchangeSegment": "NSEFO", "exchangeInstrumentID": ' & $exchangeInstrumentID & ', "productType": "' & $producttype & '", "orderType": "MARKET", "orderSide": "' & $orderside & '", "timeInForce": "DAY", "disclosedQuantity": 0, "orderQuantity": ' & $qty & ', "limitPrice": 0, "stopPrice": 0, "orderUniqueIdentifier": "' & $orderidentifier & '"}' $oHTTP.Send($pD) $oReceived = $oHTTP.ResponseText $oStatusCode = $oHTTP.Status
          
          
      But am struggling to understand and use socket.
      Would be of great help if you can have a look at the link mentioned above and help with the code sample for AutoIt.
      To connect and listen to a socket.
      Thanks a lot

      Hi, I have a site that has the following elements below: 
      <div>More element here</div> <div>More element here</div> <div>More element here</div> When I do this in Auto It:
      Local $oSelectDiv = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "div") _WD_HighlightElement($sSession, $oSelectDiv, 1) I also tried to add [3], but it doesnt seems to work:
      Local $oSelectDiv = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "div[3]") _WD_HighlightElement($sSession, $oSelectDiv, 1) It always highlight the first one, but I am trying to highlight the 3rd in the list. Is there anyway to select the 3rd div without having to add any class/id in the divs, and without using XPATH? The structure of the elements in that site were built that way.
