Batch File Automation For ARC Connection

Short answer: Yes - ARC can auto-run a script when a project is loaded. Use the second command-line parameter to specify a script name, and make that script call the EZB Connection ControlCommand to connect automatically.

What’s happening in your case

• Launching ARC with only the project file will load the project but will not automatically trigger a connection unless a script runs that calls the Connection control commands (or the EZB has been configured to connect as a client and ARC is listening).
• Your batch file example also has a typo in the path (missing space in "Program Files (x86)") and it doesn’t pass a script name parameter - so ARC loads the project but never runs a script to issue Connect.

Recommended fix (step-by-step)

1. Create a JavaScript robot skill (name it exactly, e.g., AutoConnect)

• Project Add robot skill Script choose JavaScript
• Name it AutoConnect (or whatever you prefer - you will pass this exact name to ARC on the command line)

2. Put this code in the AutoConnect script (example - tries to connect index 0, waits up to 10 seconds)

// AutoConnect script
print("AutoConnect: starting");

controlCommand("Connection", "Connect0"); // request connection of index 0
var tries = 0;
var connected = false;
while (tries < 50) { // 50 * 200ms = 10 seconds
  var status = controlCommand("Connection", "GetStatus", 0);
  if (status === true || status === "True") {
    print("AutoConnect: EZ-B index 0 connected");
    connected = true;
    break;
  }
  sleep(200);
  tries++;
}

if (!connected) {
  print("AutoConnect: failed to connect within timeout");
}
// The EZB Connection skill's "Connection Established Cmd" will then run after actual connect
print("AutoConnect: finished");

Notes:

• This uses print() as recommended for ARC JavaScript.
• Adjust Connect0 ConnectAll or Connect1..4 if your main controller uses a different index.
• If your IoTiny/EZ-B is configured in client mode (it will connect into ARC), make sure the EZB Connection skill has the "EZ-B Connection Server" enabled so ARC is listening for the device.

3. Save the project.

4. Update your batch file to pass both the project file and the script name. Example batch file (correct quoting; first param = project file, second param = script name):

"C:\Program Files (x86)\ARC\ARC.exe" "C:\Users\YourUser\Path\MyProject.ezb" "AutoConnect"

• Important: include both quoted parameters (project path and script name).
• If ARC is already running, the behavior can vary (new instance may not start). Best to ensure ARC is not running before launching the batch file.

5. Additional tips / troubleshooting

• If the IoTiny needs the EZ-B to be in client mode, enable the EZ-B Connection skill’s server option (EZ-B Connection settings "EZ-B Connection Server").
• If you launch the batch very early in Windows startup, network may not be ready. Add a short sleep or retry logic in AutoConnect before calling Connect0 (or in your batch use timeout / timeout loop to retry).
• If you want to force all connection slots: controlCommand("Connection","ConnectAll");
• If you want to connect a non-zero index: controlCommand("Connection","Connect1") etc.
• If you prefer GUI shortcuts, the Shortcut Creator wizard can set an auto-start script for you too: https://synthiam.com/Support/Skills/General/Shortcut-Creator?id=16037

  • EZ-B Connection skill: https://synthiam.com/Support/Skills/Communication/EZB-Connection?id=16041
  • Connection controlCommands (Connect0/ConnectAll/GetStatus): (see control commands in the EZB Connection manual)

Would you like me to:

• Prepare a single AutoConnect script that will try ConnectAll and then call/trigger other startup scripts, or
• Check your exact batch file line and project/script names and produce a ready-to-run .bat for you?

Tell me which EZ-B index you use (0 by default), and whether your IoTiny is set as client (connects to ARC) or server, and I’ll give a tailored script and batch file.

Great, perfect it works , i just added the script named "AutoConnect".  the second parameter was missing in the command line. thank for your help

Nice - glad to hear it works!

Quick recap and a couple of optional next steps you might find useful:

• Cause: Missing second command-line parameter (the script name) - adding "AutoConnect" fixed it.
• If you want the project to load automatically at Windows startup, use the ARC Shortcut Creator or a Scheduled Task (note: Windows auto-login may be required for true headless startup). Shortcut Creator docs: https://synthiam.com/Support/ARC-Overview/Options%20Menu/shortcut-creator
• Auto-load / CLI docs (project + script parameters): https://synthiam.com/Support/ARC-Overview/loading-saving-robot-projects/Auto%20Load%20Project

Want me to:

• create a polished startup .bat for you (I’ll need the exact ARC path and project/script names), or
• add retry logic to AutoConnect (ConnectAll, longer timeout, or repeated attempts) so it’s robust during boot?

Tell me which you prefer and I’ll prepare it.
