@override VtjCommandResult<GetDeviceStateResult> parseResponse(Uint8List response)

Parse the response bytes from the device.

Implementation

@override
VtjCommandResult<GetDeviceStateResult> parseResponse(Uint8List response) {
  if (response.isEmpty) {
    return const VtjCommandResult.failure('Empty response', null);
  }

  if (response[0] != commandId) {
    return VtjCommandResult.failure(
      'Invalid command ID in response',
      null,
    );
  }

  if (response.length < 2) {
    return const VtjCommandResult.failure('Invalid response length', null);
  }

  final status = response[1];
  if (status != 0x00) {
    return VtjCommandResult.failure(
      'Command failed with status: 0x${status.toRadixString(16).padLeft(2, '0')}',
      status,
    );
  }

  try {
    final result = GetDeviceStateResult.fromBytes(response.sublist(2));
    return VtjCommandResult.success(result);
  } catch (e) {
    return VtjCommandResult.failure(
      'Failed to parse device state: $e',
