Hello experts.
In our device we use pn7150 chip and library from SW4325.zip. I have ported it to nRF52832 MCU and successfully use for long time. All this time I send only one NDEF but now I need to send either one big NDEF or a few small NDEFs. I have tried to do both options but none work. For me, the second option is more interesting - sending a few small NDEFs. For testing I use NXP TagWriter mobile application.
What I have. For testing I have 3 NDEFs:
81 01 00 00 00 16 54 02 ......T.
65 6E 48 65 6C 6C 6F 20 enHello
6D 79 20 66 72 69 65 6E my frien
64 20 3D 20 31 d = 1
01 01 00 00 00 16 54 02 ......T.
65 6E 48 65 6C 6C 6F 20 enHello
6D 79 20 66 72 69 65 6E my frien
64 20 3D 20 32 d = 2
41 01 00 00 00 16 54 02 A.....T.
65 6E 48 65 6C 6C 6F 20 enHello
6D 79 20 66 72 69 65 6E my frien
64 20 3D 20 33 d = 3
After sending the first NDEF I have a callback from the library that NDEF has been sent. Inside of this callback I set the second NDEF. Then I have a callback again, and now I set the third NDEF and that is all. NDEF is not sent and no callbacks occur. So, I can’t send more than 2 NDEFs. I have tried another NXP mobile application - TagInfo - and have the same result. Also I have tried another applications and have even worst results - only one NDEF is sent then.
I assume that I prepared the wrong NDEF or I am not using the library correctly.
Thank you in advance for your help. I am ready to answer any additional questions on your part.
Best regards,
Alex.

Hi Alex,
Do you want to implement a T4T response to a single poll command with multiple response? What is the change you made in SW4325 project except the porting part? Please kindly clarify.
Have a great day,
Kan
