Unable to read tag UID #26

Hi skjolber and thank for this great collection of nfc tools. I am using the server-example application and try to get the tags UID. With Mifare Desfire tags there is no problem and it works perfect. But at MIFARE Classic 1k tags the logs always shows the following logs: 2020-09-07 08:43:32.053 3791-3803/com.github.skjolber.nfc.external I/com.github.skjolber.nfc.service.BluetoothBackgroundService: onCardStatusChange sta: Present. 2020-09-07 08:43:32.057 3791-3803/com.github.skjolber.nfc.external D/com.github.skjolber.nfc.service.BluetoothBackgroundService: Power on card.. 2020-09-07 08:43:32.138 3791-3803/com.github.skjolber.nfc.external D/com.github.skjolber.nfc.service.BluetoothBackgroundService: onAtrAvailable: 3b8f8001804f0ca000000306030001000000006a 2020-09-07 08:43:32.139 3791-3803/com.github.skjolber.nfc.external D/com.github.skjolber.nfc.service.BluetoothBackgroundService: Got tag type MIFARE_CLASSIC_1K 2020-09-07 08:43:32.141 3791-7026/com.github.skjolber.nfc.external D/com.github.skjolber.nfc.service.BluetoothBackgroundService: Regular mode 2020-09-07 08:43:32.615 3791-7026/com.github.skjolber.nfc.external W/com.github.skjolber.nfc.service.AbstractService: Unable to read tag UID

Am I doing something wrong or does the application not support MIFARE Classic 1k?

Mifare classic cards are not supported by most phones nowadays.
