Hello,

I'm trying to use the VisualTagConnection in order to read a bar Codes with a 6131.
In my MIDlet, one of the first thing i do is to try to know whether the needed symbologies are supported by the API implementation:

String[] symbologies = SymbologyManager.getReadSymbologies();

But this method (SymbologyManager.getReadSymbologies())return me null. Does it means that no symbologies are supported by the API ? Or should i do other things before this instruction ?

Thanks for your help,

hi prasanna

Which device are you using NOKIA 6131 or NOKIA 6131NFC?

NOKIA 6131 do not support contactless communication. if you use NOKIA 6131NFC it only supports RFID tags

I'm currently using the 6131NFC. I can use correctly NFC communication but i have some problems to use the VisualTagConnection, specially when i try to know whether the needed symbologies are supported by the API implementation.

Hello!

I work with an emulator of 6131 and a function getGenerateSymbologies() returns me only "ean-upc". Function getReadSymbologies() returns me only "code-39".

SymbologyManager.getReadSymbologies()
Returns the list of symbologies that are supported by the API implementation for reading visual tags.

SymbologyManager.getGenerateSymbologies()
Returns the list of symbologies that are supported by the API implementation for visual tag image generation.

Before the purchase of telephone I would like to know
with what types of tags able to work a real device?

I very ask to help in the decision of this problem...

Hi all,

Please note that there's a new section here at Forum Nokia specific to NFC. It is here - http://discussion.forum.nokia.com/fo...play.php?f=144

I have not tested what you are talking about but I can give it a try, I will let you know. Unfortunately I don't have a Nokia 6131 NFC here it me for testing.

Kind regards,

Well, it does support SOME parts of JSR-257... Visual Tags are NOT one of them, at least in FW version 3.12...

It would be great if someone can give some info about which parts of the JSR-257 are currently supported.

HI prem

AFAIK it supports RFID tags only...

Hi!
First of all, thanks for the reply.

In the SDK documentation, more precisely in the package javax.microedition.contactless.visual, there's an example on how to generate and read visual tags.
[(...)Nokia_6131_NFC_SDK_1_1/docs/nfc/javax/microedition/contactless/visual/package-summary.html]
I made some minor changes to the example (built a MIDlet, got the image from the phone's camera, etc) and I get the following exception:
javax.microedition.io.ConnectionNotFoundException: The requested protocol does not exist vtag://

This probably means that this phone doesn't have this part of the JSR-257 implemented yet
