RFD8500 on iOS 11

Hi,

I have problem with RFD8500 on iOS 11.

I make try with RFID Mobile app.
The reader is connection is fine and stable, but i am not able to export the data. I've tried on Android and there everything works fine as expected.

From user guide I couldn't find step that I missed. The settings are same as on Android device. I'm using iPad model A1822 with iOS ver 11. Please help
