NXP - registration failed

[nathD]

Hello,

I encounter this error using NXP for reading NFC card !

 "Error while NxpNfcLib register"

This error has been occurring on newly registered smartphones since january, but not on my old ones.

Does this have anything to do with the problem described below ? :

I haven't found any information on the status of the key generation problem.

Thank you

Hello,

Thank you for your interest in our products.

Could you please help me with a little more information about your setup?

What Taplinx version are you using and, please help us by sharing the Android version you are using aswell.

Hello, thank you for your reply.

For reading NFC cards, we are setting up an observer. After each reading, we kill the observer to restart it. This way, we can continue reading the NFC cards.

We use 2 phones, with Android 9 version. Only the build differs. The smartphone model is the same, but one of the phones can't be upgraded to a higher build version (there may be a hardware difference).
our 2 builds are as follows:

-20200403_R1.12 (oldest phone, without the reading problem)
-20240129_R1.12

I use this NXP version : nxpnfcandroidlib-1.9

On the first build, I can read several cards in a row without any problem.
On the 2nd build, I make a 1st reading, then the observer doesn't relaunch. I have to quit the application and relaunch it.

Thanks

Hello sir,

This may be a problem for us since our development of Taplinx is always tested and built to work in the newest Android version. If you aren't able to update the phone our support could be very limited due to the problems for reproducing the issue.
