问题


I am trying to send APDU commands to NFC card that contains ISO7816 Tag I will open session:

readerSession = NFCTagReaderSession(pollingOption: [.iso14443], delegate: self, queue: nil)
readerSession?.begin()

Once the tag is detected,

session.connect(to: tags.first!)

and start sending APDU commands one by one.

detectedTag.sendCommand(apdu: apduCommand) { (response: Data, sw1: UInt8, sw2: UInt8, error: Error?)

But after about 20 seconds NFCTagReaderSession is sending the error:

Error Domain=NFCError
Code=201 "Session timeout"
UserInfo={NSLocalizedDescription=Session timeout}

Is there a possibility to increase the timeout of communication with connected tag? I tried looking for interval or timeout property of NFCTagReaderSession. But no luck.
