Implementation

@override

  String payload = '$ident;';
  payload += '$firmwareId;';
  payload += '$firmwareBuild;';
  payload += '$deviceId;';
  payload += '$hardwareId;';
  payload += '$modelId;';
  payload += '${firmwareBranch.toPacket()};';
  payload += '${fotaEnabled ? '1' : '0'};';

  String crc = calculateCrc(payload.codeUnits).toRadixString(16).padLeft(4, '0').toUpperCase();

  return '<Pi>$payload$crc</Pi>';
