Hi,

I am working on an NFC application and would like to know if the device NFC antenna is turned on or off on the device.

I am using the following method to check  the same

DeviceCapability.isNFCAvailable()

But some times the OS if giving me wrong information.

So started looking for a class which gives exact information but could not find.

Could anyone help me.

Can this post help ? http://developer.blackberry.com/native/reference/bb10/nfc_libref/topic/nfc_settings_t.html

Sorry to say that I am working on Blackberry java. The link you pointed is for BB10.

I've used a combination of isNFCSupported and isNFCEnabled isNFCAvailable.

Can you expand on the behaviour that you are seeing?

Thanks!

Hi robbieDubya,

I need to show a customised popup informing the user to turn NFC antenna ON if it is OFF. Some times when using this method

DeviceCapability.isNFCAvailable()

it returns true even if antenna is turned off. So I cannot rely on this method.

Started looking for alternative methods in the API but could not find.

Hope this inormation helps.

Note : There is a method available in NFCManager.enableNFCByPrompt which might serve my purpose but I want to customise the message.

Whoops, sorry my mistake.

I don't have a lot of experience in Java Development, but there will be probably somebody more experienced who can help you.
I hope you can find a solution to your problem.

Should be accurate, can you confirm which build is running on the device(s) where you're seeing this behaviour?

[vvenu88]

Device : Blackberry 9900

Build : 7.1 Bundle 2061, (v 7.1.0.714,platform 5.1.0.532)

Most of the times it gives me correct NFC antenna status, but at times api gives me wrong information.

Do you have any steps to reproduce?

[vvenu88]

No particular steps, it occurs randomly.
