Can anyone tell me how to find the status of NFC radio whether its in ON state or OFF state using J2ME API?

Using System.getProperty("microedition.contactless.version") statement I am able to find out, that NFC is supported by the device or not.

But I am unable to get the status of NFC radio. Do we have any methods to enable in J2ME using which NFC radio can be enable ?

Hoping for quick response.
