NFC hrs sample truncated ndef

Hi

I am using an Identive NFC reader/writer SCL3711 and their sample app to read tags.

In the sample app, through the debugger I can see that it is registering an NDEF message which is >200 bytes long.

When I read using the Identive reader it always comes back with a message which is 142 bytes and then when I analyse it, I can see that there is definitely a truncation.

Using a Nexus 7 I can pair via NFC which suggests that the Nexus is reading the entire ndef message.

Just in case, i have also used a SCM3712 nfc reader from Identive and that also gives me the same 142 bytes.

Perhaps the Identive SDK has a bug. However, after I pair with the Nexus, the app changes the NDEF to something else which is used to launch an android app and that happens. This time I can read that entire packet - but it is 137 bytes long.

Hope someone can comment and help me understand the issue.

Kind regards Mahendra
