Unable to set EXTRA_DATA params to BARCODE plugin

[nicolomanni]

Hi Darryn,

i'm trying to set/update EXTRA_DATA params like decoder_code39_convert_to_code32 without success.

This is my configuration that I send to 'com.symbol.datawedge.api.SET_CONFIG':

const profileConfig = { PROFILE_NAME: AppProfileName, PROFILE_ENABLED: 'true', CONFIG_MODE: 'UPDATE', PLUGIN_CONFIG: { PLUGIN_NAME: 'BARCODE', RESET_CONFIG: 'true', PARAM_LIST: { EXTRA_DATA: { decoder_code39: 'true', decoder_code39_convert_to_code32: 'true', }, }, }, APP_LIST: [ { PACKAGE_NAME: AppBuildName, ACTIVITY_LIST: ['*'], }, ], }

DataWedge version 7.0.4 Where am I wrong?

Looks like you have some invalid JSON, please take a look at https://github.com/darryncampbell/DataWedgeCordova/blob/master/www/js/index.js#L68 which is a known working example and build from there.

I usually use http://json.parser.online.fr/ to find any JSON errors

[nicolomanni]

Sorry for the code formatting. The configuration updated is:

The datawedge profile is correctly created as before with decoder_code39 option set to true but without the option decoder_code39_convert_to_code32

I'm following this guide: https://techdocs.zebra.com/datawedge/7-6/guide/api/setconfig/ How can I pass it the EXTRA_DATA decoder Parameters?

[darryncampbell]

That's still not valid JSON though is it? I mean you have trailing commas at the end of your lists. Also, things like PROFILE_NAME should be strings.

[nicolomanni]

That's my typescript object that will be converted to JSON when sent to datawedge API just like the example you given me: https://github.com/darryncampbell/DataWedgeCordova/blob/master/www/js/index.js#L68.

The trailing commas are added automatically from the Prettierjs/TSlint configuration, in no way affects the generation of the JSON.

AppProfileName and AppBuildName are variables that contain the name and the buildName of my application.

:/ I don't know... the next step would be to test with native code to see if it is a bug in DataWedge or something else. I will try to take a look if I get a chance over the next few days - the plan is to just modify https://github.com/ZebraDevs/samples-datawedge/blob/master/DataWedge-API-Exerciser/app/src/main/java/com/zebra/datawedgeexerciser/MainActivity.java#L324 to add the convert_to_code32 attribute and see if that works.

[darryncampbell]

You are passing the correct strings at the correct place, I tested with:

barcodeProps.putString("decoder_code39", "true");
barcodeProps.putString("decoder_code39_convert_to_code32", "true");

in native code as I said in my previous comment and that works. You might want to try specifying

scanner_selection: 'auto'

To ensure you are applying the configuration to the correct scanner

Hi, I'm having trouble with something similar, and I was hoping you could help out. I'm trying to set extra parameters on my barcode scanner profile (ie aim_type, same_barcode_timeout, decode_haptic_feedback, etc), and nothing I'm doing is changing the settings on my profile. I'm confused by this line in the docs:

BARCODE – takes a value from the Scanner Input Parameters table below; specify decoder and other input settings as EXTRA_DATA in the PARAM_LIST nested bundle.

What does it mean EXTRA_DATA? Is that just supposed to be another JSON object? Here is what I have:

const profileConfig: DatawedgeProfileConfig = {
      PROFILE_NAME: 'InventoryManagement',
      PROFILE_ENABLED: 'true',
      CONFIG_MODE: 'OVERWRITE',
      PLUGIN_CONFIG: {
        PLUGIN_NAME: 'BARCODE',
        RESET_CONFIG: 'true',
        PARAM_LIST: {
          configure_all_scanners: 'true',
          scanner_input_enabled: 'true',
          beam_timer: '60000',
          same_barcode_timeout: '5000',
          different_barcode_timeout: '0',
          aim_type: '5',
          upc_enable_marginless_decode: 'true',
          '1d_marginless_decode_effort_level': '3',
          poor_quality_bcdecode_effort_level: '3',
          decode_haptic_feedback: 'true',
          decoding_led_feedback: 'true',
        },
      },
      APP_LIST: [
        {
          PACKAGE_NAME: ApplicationConstants.APP_STRING,
          ACTIVITY_LIST: ['*'],
        },
      ],
    };

I've also tried changing PARAM_LIST to:

PARAM_LIST: {
          configure_all_scanners: 'true',
          scanner_input_enabled: 'true',
          EXTRA_DATA: {
              beam_timer: '60000',
              same_barcode_timeout: '5000',
              different_barcode_timeout: '0',
              aim_type: '5',
              upc_enable_marginless_decode: 'true',
              '1d_marginless_decode_effort_level': '3',
              poor_quality_bcdecode_effort_level: '3',
              decode_haptic_feedback: 'true',
              decoding_led_feedback: 'true',
          }
},

but still no luck. The profile is created when I make the setProfile call, but the extra settings are never updated in either case. Can anyone provide some insight here? Thank you.

Hi @kylebrennan , sorry I just saw your comment - are you still facing issues? There is a demo app that calls the DataWedge API at https://github.com/darryncampbell/DataWedgeCordova.

[darryncampbell]

For the original issue, I have asked the docs team to update the docs & examples to clarify that the scanner must be specified as part of the call to SET_CONFIG: https://techdocs.zebra.com/datawedge/8-0/guide/api/setconfig/ (we had another, very similar issue raised along these same lines)

[darryncampbell]

Techdocs has now been updated.
