Actually, the SDK provided with the device is working on Android Gradle 7.0.3 which is quite old. We tried to upgrade the Gradle to 8.4 version but we faced issue. We would like to get confirmation from you that its possible to upgrade Android and Gradle version and still use your SDK. also can we upgrade the Android firmware in order to use flutter for some app development ?

Hello team, I was able to check the demo for the NFC Mifare classic. The problem with the demo is you need to press a button to open the nfc, then you need to press another to authenticate and finally press another to read. With our app we need to be able to do all this steps without user interaction. Apart from that we need the app to be listening all the time for an incoming nfc tag. That’s why I was asking you last time if there’s something like a listener similar to the one you have with the QR Reader (setHardReaderListener). I would really appreciate if you can help me with this. Thank you.
