CIQ SDK 8.4.x (Windows): run and install silently fail for Data Field projects (Edge 540)

Summary
On Windows, with Connect IQ SDK 8.4.1, Data Field projects build successfully but cannot be run in the CIQ Simulator or installed on an Edge 540. Both run and install commands fail silently (no error output), and the simulator opens only in idle shell mode with no device window.

Environment

  • OS: Windows (10/11)

  • SDK: Connect IQ SDK 8.4.1 (Windows)

  • Device: Edge 540

  • App type: Data Field

Project status

  • Project structure is valid (manifest.xml, source/*.mc)

  • manifest.xml:

    • type="datafield"

    • correct entry

    • product edge540

  • Entry class exists and matches manifest entry

  • current-sdk.cfg correctly points to SDK 8.4.1

  • connectiq.bat build succeeds with no warnings/errors

Steps to reproduce

  1. Create or open a valid Data Field project for Edge 540.

  2. Run connectiq.bat build → succeeds.

  3. Run any of the following:

    • connectiq.bat run

    • connectiq.bat run -d edge540 -t datafield -p .

    • connectiq.bat install -d edge540

  4. CIQ Simulator opens but remains idle (no device window).
    No CLI errors or output are produced.

Expected result

  • Simulator launches an Edge 540 device window running the data field, or

  • install reports successful installation to the device.

Actual result

  • Silent failure: no device window, no installation, no error output.

Notes
This appears to be a regression or tooling issue in SDK 8.4.x on Windows. The same project configuration is valid and builds correctly, but cannot be executed or installed.

  • Bro this is slop, and such a great example of everything that's wrong with the internet, writing, and software development in 2026. You're wasting everyone's time, including your own (if there's even a human behind this at all).

    > connectiq.bat build succeeds with no warnings/errors

    connectiq.bat doesn't build your project, it opens the simulator, so it's not possible that it "succeeds with no warnings/errors" (with the implication that it actually builds your app).

    no x, no y, no z - common clanker tell

    > This appears to be a regression or tooling issue in SDK 8.4.x on Windows.

    I also see this in other clanker bug reports / posts. Assertion that something is a *regression*, without proof.

    If it were actually a regression, then you could point to the same steps working on a previous version of the SDK, but there's no mention of that in this bug report. And in fact the same steps wouldn't work on any version of the SDK, because that's not how connectiq.bat is supposed to work.

    To resolve your issues, you could:

    - just build and run using the Monkey C extension in VS Code, as intended

    - follow the instructions from Garmin on using Monkey C from the command line

    You might actually have to think for yourself tho, or read text that hasn't been vomited up from an LLM.

  • It's not clear what and why you do the way you do.

    Does whatever you're trying in SDK 8.4.1 work in any previous version?

    Why do you try it from cli? Try one of the SDK samples and use VSCode. Once you succeed from there move to cli (if you really have a reason to do so, besides the AI telling you) Then start to modify the sample code and add your features.
