6131 NFC autostart on tag touch

[mariosas]

even this wont work on the phone for some reason!!!! same error as before:Invalid application no idea wat the problem can be

it loads in the emulator though...

first only entry
MIDlet-Push-1: ndef:rtd?name=urn:nfc:wkt:RFID_TAG,xxx.de.Reader,*
and check the install
and the next
add the next
MIDlet-Push-2: ndef:rtd?name=urn:nfc:wkt:NDEF_TAG,xxx.de.Reader,*
and check the install

Error? Then Midlet-Push-2 ... not correct!

Is the install with none pushentrys correct?
If not, then is MIDlet not correct
or device error

Hi all,

I am not sure if this question has already been asked. Please direct me to the appropriate post if u know it has infact been.

okay wat i want to do is this. I have a P2P application. In Phone 1 the app is trying to open up an NFCIP connection with Phone 2. After the connection.open() function has been called the phone 1 is brought closer to phone 2. Now phone 2 must identify phone 1 (pushregistry) and establish the NFCIP connection.

I tried registering to push registry with nfc:undefined_format. The problem is phone 2 will not start the app if phone 1 is trying to open up the NFCIP connection. But if I just bring phone 1, without trying to open up the connection, phone 2 will start u the app.

I guess this is because of the connection string in pushregistry. Please help. Many thanks!

Hello again,
I can successfully auto-launch the application with "any" tag using:
String pushEntry = "nfc:undefined_format";
PushRegistry.registerConnection(pushEntry,//ndef:rtd?name=urn:nfc:wkt:T
midletClassName,
"nfc:rf;type=jewel;uid=*");//try between rf or ndef

Ok, I've tried absolutley everything...but it simply wont launch, always "Unknown service type".....right now i dont care about specific tags, or if they have data or not. I just want any tag that is touched to launch my MIDlet, the above seems to be the direction my java needs to go, but even that wont work.

would someone be able to supply a sample project (with source) that actually works for me to look at?

Thanks for all the help so far.

The problem is here, which some entries will not correctly indicate

[mariosas]

Registrie examines only for:

PushRegistryImpl::registerConnectionInternal registering connection: ndef:rtd?name=urn:nfc:wkt:U
PushRegistryImpl: URL prefix='ndef'
PushRegistryImpl: Found handler for prefix.


'ndef' and not more
and not ...'rtd?name=urn:nfc:wkt:U'

and not ...'rtd?name=urn:nfc:wkt:U'

i know....

Does anyone know how to start application when phone is touched with a reader?

[mariosas]

Do not understand wrongly.
The Push Registry examines only more handler for prefix and not the complete indication. the problem is the name =
Like the registration to look I must already wrote.
One must read all entries.

FINALLY...it works using:
case DeviceEvent.EVENT_CONNECTION:
try{
String pushEntry = "nfc:undefined_format";
String pushFilter = "*";
PushRegistry.registerConnection(pushEntry, "Application", pushFilter);
} catch (Exception e) {
}

break;
}

but as we know, this only works for 'empty' tags....i have some tags with formatted data, but i dont need to read the data at loading...anyone know how i get all my tags to load the MIDlet?

You mentioned before that your tags contain NTIP data. The Push Registry string in this case should be:

"nfc:ntip?name=<ntip fqn>"

where ntip_fqn is the Fully qualified NTIP record type name.

Do you know the record type for your tags?

As is to be understood?
1.the entry in registry is accepted?
2.Midlet starts automatically with an empty TAG?
3. current Midlet reads empty TAG?
This entry in jad does not function however!

catch (Exception e)
{
// empty entry = no examination whether entry was correct!!
}

yes, you understand correctly...

I have different tags, some with NDEF, some with NTIP, some empty.

Also some MF0U1, some JEWEL...

but only empty ones load.

The following entry does work in the jad file as well:
MIDlet-Push-1: nfc:undefined_format,com.nokia.nfc.sample.app.TagTestMidlet,*

You have to:
1. Install the MIDlet that has the above entry in the jad file.
2. Run the MIDlet once on the phone.
3. Close the MIDlet.
4. Touch any empty tag or any tag that doesn't contain NDEF or NTIP data.

Your MIDlet will be automatically launched.

yea, thanks...im not using the jad anymore to do this, like i said...i got it to work using the code for empty tags.

Yes, but I was mentioning this for mariosas. Some of mariosas' earlier posts, as well as this one, imply that the Push Registry entry for empty/non-NTIP/NDEF tags is not working if it is registered in the jad file, when in fact it does work.
