Topic: 3DES authentication timeout

Hello,
I'm currently working on a Android app that  handle the mifare ultralight 3DES Auth.
My problem is that I do a request to a server to handle the generation of the RndA+RndB' challenge and It seems that the request is to slow.
When I send to next apdu to continue the authentication I have :
android.nfc.TagLostException: Tag was lost.

Is there a way to increase the timeout between the two requests ?

Thanks in advance,
Christophe
