I am trying to send infromation from PN7150 to ioS app using NDEF format. I see this sometimes working and sometimes NDEF information is not shown on the app which I developed using the ioS NFC SDK. For android, the behaviour is consistent and able to fetch information from the PN7150.  Also I see that when the length is greater then 255 it doesnt work for Android. I am using NXPNCI library for fetching the information and have put it in card emulation mode. here are the NCI Log statements where iOS app is unable to read the NDEF

NCI << 00 00 0d 00 a4 04 00 07 d2 76 00 00 85 01 01 00
NCI >> 00 00 02 90 00
NCI << 60 06 03 01 00 01
NCI << 00 00 07 00 a4 00 0c 02 e1 03
NCI >> 00 00 02 90 00
NCI << 60 06 03 01 00 01
NCI << 61 06 02 03 02
