Using plugin to scan a barcone on Zebra TC57

[hiryuken]

Hello @darryncampbell ,

I am trying to use the plugin on a TC57 device. Actually I am having troubles even just running the test application on that device and it seems that I can send the command to the zebra to start scanning, I can even get some event back, but I don't get any data but if the IR is fired and is reading something.

I Can also tell you that I can enumerate the scanners, but it seems i can't set the profile I want.

I wonder if you can give me any advice on how to let it work

I'll attach the service I am using (mostly the same from your example).

Thanks for your help,

Alessandro

Hi,

• Which test app are you trying to run?
• Which version of DataWedge does your device have (https://techdocs.zebra.com/datawedge/7-0/guide/about/#whichversionisinstalled)?
• Is the DataWedge profile being created?
• Can you please try restoring DataWedge and launching the test app again (DataWedge app --> Settings --> Restore)?

Hello Darryn and thank you very much,

I am trying to run this https://github.com/ZebraDevs/DataWedge-Ionic-Demo

DataWedge version: 8.0.37 Scanning Framework version: 23.1.13.0

The DataWedge profile ZebraIonicDemo is being created but is not used by the app (in the app the active profile is always Profile Default0).

I did try to restore the DataWedge and launching the app, but i have the same results.

Thank you for your help.

Hi, strange, can you please confirm that the 'associated applications' in the ZebraIonicDemo profile points to the demo application? That version of DataWedge should be sufficient to run the demo

[hiryuken]

Hello, yes I can post you here some pics from the Zebra, it seems that the profile points to the demo application.

[darryncampbell]

I tried changing the language of my TC52 in case this was related to language but it still works fine for me. I can install the ZebraIonicDemo and the Active Profile shows as "ZebraIonicDemo" rather than "Profile0 (default)" which is what you see.

I do have a TC57 in my drawer. What BSP are you running? Settings --> About Phone --> Build number. I will then test it on a device configured exactly the same as yours.

@darryncampbell Thank you very much, reading your answers we could find out what was going wrong. Actually it was just my mistake in giving the wrong name to the ionic App. The app ID wasnt matching properly the DataWedge profile so it wouldn't "connect" and the events were missing. I could change the App ID and recompiled the app and now it works perfectly! Thank you very much for your precious help!
