NFC Functionality?

[geri-m]

Hi,

before starting to develop Midlets for the BenQ T80 I do have some basic questions:

- Although NFC is turned on (Settings => NFC Function settings => RF-Tag detect function => on AND  CommManger => (8) NFC  RF-Tag Detect "on") nothing happens when putting a Tag (ISO14443-A, NFC Forum Compilant [Topaz or Desfire]) to back of the phone. It seams like there is also no electromagnetic field emmitted by the phone in idle mode. This is the normal behavior? In the Manual (page #28) it says that the phone should at least vibrate ...

- When I put the BenQ T80 (with a Secure Mico-SD-Card inserted) onto a Smartcard Reader (ISO14443-A or B [Omnikey]) the reader does not detect the phone in tag emulation mode. So how do I put my phone into tag/card emulation mode? Can this only (!) be done by a midlet?

- In the englisch Manual (v. 0.0.6) it says on page #28 that a NFC SIM is required. This is actually quite strange, as I throught the SD-Card is the secure element. In the NFC Function setting I'm also not able to choose a certificate resource. Is this a necessity?

Cheers, geri-m

Hi geri-m,

Usually, the MIDlets are not able to start to use the NFC capabilities if they don't call first this function:

    com.sirit.nfc.Hardware.NFCRequestEnabledADD(true);

It should be placed in the early stages of your MIDlet, for instance, in the constructor of your MIDlet. Could you check this?

The manual is still a draft, so there are some mistakes (i.e. SE on a SIM card).

Best regards,

Jose

Hello geri-m,

all the thingss you mentioned work normaly with my t80 phone. For example, if I put the Topaz tag on the senosr zone, and the  RF-Tag detect function is on, the phone vibrates. I have also tried it with the Omnikey reader, an dthe reader detects it normaly. I even tried it to read the internal MiFare card with the Nokia 6131NFC and it reads the internal tag of the t80 normally. Although reading the Topaz tag, it takes a bit longer to read than reading i.e. MiFare tag.

Cheers,

Hi Samo,

my BenQ is not not detected by any reader, nor does my phone detect any tag/smartcard [without a J2ME application]

Any hints what to do -- or is my phone broken?

Kind Regards,

Geri-m

Hey geri-m,

I have had similar problems with my T80 and here is what I do if I got NFC problems.
First of I try to turn of the phone, take the cover(NFC antenna) off and take out the battery then you assemble it together and turn on the phone and it should work(This works for me in 90% of cases when NFC stops to function). If this doesn't help me, then I use the Master  Reset function in System tools. It restores the factory settings(All of the data on the phone will be lost!!!!!!!), and the phone starts to work, as it should.

I hope this helps...

Samo

mhm, no -- still does not work. To I have to activate tag/card emulation somehow?

very strang.

Cheers, geri-m

Hmmm... That is strange, perhaps there is something wrong with your T80. Hope Jose has more information about this.

Hi Geri-m

My BenQ is detected by the external reader only if it has the microSD card you should have received with the BenQ T80. These microSD have the secure element. The BenQ T80 does not bring default secure element. Could you check this?

Best regards,

Jose

Hi Jose,

yes, there is a secure SD (the red ones with the SMX) in the card slot. I already exchange it against another one, in order to make sure the it is not due to a broken card.

Hi Geri-m,

I would like to know what is the card reader that you are using, in order to know the BenQ T80 is compatible with your reader. I am using one SCM Microsystems SDI010.

Greetings,

Jose

I'm using an Omnikey 5313 (ISO 14443 A & B compliant) and a NXP Pegoda.

Secondly I'd like to add that accessing the secure element from a J2ME application does not work either:

This code simplet simple does nothing ...

<code>
            try {
                ISO14443Connection conn = (ISO14443Connection) Connector.open("nfc:InternalISO14443");
                str.setText("Channel Open");
            } catch (IOException ex) {
                str.setText("Error Opening Channel " + ex.toString());
            }
</code>

I already tried it with different SD-Card. The memory of the SD Card is avaible to the phone. Thus I suppose there is something wrong with my phone/SD cards. Who do I have to turn to in order to have this issue fixed?

Cheers, geri-m

Hi geri-m

In order to access to the secure element, you MIDlet must to be signed, is this signed?

Best regards,

Jose

[josergc]

When you place your T80 over the reader, is it open (showing the keyboard) or close?

[geri-m]

Okay, I found the issue: 3 out of the 5 SD-Card are not working (!). With 2 of the card I can use the tag-emulation as well as access the scure element from J2ME ... (and yes, the MIDlets are signed)

cheers, geri-m

Hi geri-m,

If you want new microSD cards, please send back to Cell-Idea these 3 no working microSDs, and Cell-Idea will send to you 3 other new.
