auth method

Future<void> auth()

Authenticates with the device using the provided password.

This method is called automatically during the connection process if the device requires authentication.

Throws ZKErrorResponse if authentication fails.

Implementation

Future<void> auth() async {
  final key = makeCommandKey(password, sessionId);
  final response = await sendCommand(
    CMD_AUTH,
    commandString: key,
    bypassConnectionCheck: true,
  );
  final responseHeader = parseHeader(response);
  final responseCode = responseHeader[0];

  if (responseCode != CMD_ACK_OK) {
    throw ZKErrorResponse("Authentication failed with code: $responseCode");
  }
}
