my main issue for now, is managing to handle Ultralight EV1 tag. for that we are used to send raw APDU. I have tried, to use the nfc.transmit method, but I suppose it needs to receive more than just the basic apdu code, and it's more low level than I expect. Basically I'm used to transceive : 0x60 -> GET_VERSION 0x1B... -> PWD_AUTH 0x30... -> FAST_READ ... But here passing those value give me errors. I had no issue using the m1_authenticate m1_read_block m1_write_block If you have some sample code, managing to read/write or send the GET_VERSION apdu to an ultralight code, it should be enough for me to take after.

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 ?

They are connecting external printer via USB but sometimes printer get disconnected and they need to disable and enable usb mode on TPS530 to make it works again. Is there any API or command which can disable and enable USB mode? Currently, we need to open Settings > About > Security Bootloader > tap 5 times
