CC3220SF: Default role set via CLI

Part Number: CC3220SF
Other Parts Discussed in Thread: UNIFLASH

Hello TI!

I am able to change default device role of CC3220SF (Station or Access Point) using Uniflash GUI. 

Now I need to do the same on build server. 

I have found document swru469h (chapter 7.1.10 Reconfigure Project).
I have changed shell script running on the build server by adding "reconfig.json":

...
# change default role to AP
project reconfig --name "$IMAGE_NAME" --file reconfig.json
# create SLI file
"./$IMAGE_CREATOR_BIN" project create_image --name "$IMAGE_NAME" --sli_file "$DIST_SLI_IMG"

reconfig.json content:

{
  "SimpleLink":
  {
    "startRole": "Station"
  }
}

I have tried "Access Point" instead of "Station" but I have Access point role all in both cases.
What I am doing wrong?

    I will need to check with our tools team.

    Since I'm not an expert of the CLI and haven't tried this before I used the Uniflash GUI to switch between the initial roles (Advanced Mode - Role Settings > General Settings) and checked the auto-generated json file (under C:\Users\<username>\.SLImageCreator\projects\<projectname>\) and it looks different than the definitions in the document (e.g. "CONFIG_TYPE_MODE": { "START_ROLE": "0" } under  -> for station, or "2" -> for AP).

    Maybe you can try this while i'll check with the experts about the content of the uniflash/image-creator document.

    Hi Kobi,

    I have tried these two options in my reconfig.json file without any success (AP starts always):

    {
      "systemFiles":
      {
        "CONFIG_TYPE_MODE":
        {
          "START_ROLE": "0"
        }
      }
    }


    {
      "CONFIG_TYPE_MODE":
      {
        "START_ROLE": "0"
      }
    }

    are you calling sl_WifiConfig() in your code? 

    This one changes the role setting according to "Simplelink WIFI->General->Start Role" definition in the syscfg.

    So if you call sl_Start() after sl_WifiConfig(), it will take the definition from the syscfg.

    I saw that at least the programming from the GUI uniflash works (when not using sl_WifiConfig). I will later try to program from the CLI using the json file generated by the GUI.

    sl_WifiConfig() is not used within our code.

    I do not know what you are referring to with 

    "Simplelink WIFI->General->Start Role" definition in the syscfg but it seems to be irrelevant as soon as we are not using function sl_WifiConfig().

    again, i'm not sure what exactly is your issue and I'm still waiting for response from our tools team about the "reconfig" command.

    However, i just tested the following and it worked so probably can work for you.

    Created an ImageCreator project (called "CC3235SF-1") with the GUI "Simple" interface (only updated the SP).

    Programmed it with: 

    C:\ti\uniflash_6.3.0>dslite.bat --mode cc32xx project program --name CC3235SF-1 --dev

    Ran a program and checked the sl_Start return code.

    It was AP (2).

    Opened to auto-generated json file and updated the following line (default value was "2"):

    "START_ROLE":"0",

    Reprogrammed it and ran the example again.

    Return code of sl_Start is now 0 (Station) as expected.

    JSON in my case is generated on build server for every Git commit. I cannot change the value manually. (I am programming my device offline with SLI image from build server.)

    Also: I would prefer to wait for response from expert from tools team rather than being tester of some undocumented ideas.

    Bottom line is that the json in the project that you program should have the "START_ROLE":"0" line and then the NWP will start as station.

    I guess the reconfig command doesn't do the work. I haven't tested this command yet (I may have time for it later today) but all it does is updating the json (text) file which can be done through other tools.

    I expect the tools team will response early next week.
