VHL command group
VHL stands for Very High Level card access. With this command group, you can handle nearly all aspects of the card technology used in your project while avoiding complex low-level command sequences.
You cannot mix VHL and low-level commands.
For more details on how to implement VHL, please see our VHL workflow overview.
|BRP status||BRP Library Error Code||Mnemonic||Description|
This status code occurs in the following cases:
This status code is the only one that requires a reselection of the card with VHL.Select.
|0x02||0x0102 (258)||VHL.ErrCardNotSelected||The command can't be run because no card is selected.|
|0x03||0x0103 (259)||VHL.ErrHf||Communication problems with the card occurred. Data may have been corrupted.|
|0x04||0x0104 (260)||VHL.ErrConfig||The VHL file structure in the reader configuration is invalid or the specified VHL file isn't available.|
|0x05||0x0105 (261)||VHL.ErrAuth||An authentication error occurred. Data may have been written partially. This may occur if the specified VHL file uses invalid keys (MIFARE) or the specified stamp is not in the reader's EEPROM (LEGIC).|
|0x06||0x0106 (262)||VHL.ErrRead||The communication sequence was OK, but reading failed. The card remains selected. This may occur if the specified VHL file is too long for the physical card storage.|
|0x07||0x0107 (263)||VHL.ErrWrite||The communication sequence was OK, but writing failed. Data may have been written partially. The card remains selected. This may occur if the specified VHL file is too long for the physical card storage.|
|0x08||0x0108 (264)||VHL.ConfcardRead||A BALTECH ConfigCard has been detected successfully and will be read after this command.|
|0x09||0x0109 (265)||VHL.ErrInvalidCardType||The desired card type doesn't match the card family of the currently selected card.|
|0x0A||0x010A (266)||VHL.ErrNotSupported||The command is currently not supported. Future releases may support the command.|
|0x0B||0x010B (267)||VHL.ErrFormat||The communication sequence was OK, but formatting failed. Data may have been written partially. The card remains selected.|
|0x0C||0x010C (268)||VHL.ErrHw||An error occurred while communicating with the reader chip/SAM.|
