CRC calculation for QByteArray incorrect

[nikitaroz]

The circular redundancy check (CRC) calculated for a QByteArray does not match the one calculated by the miniboard. This means that the base station effectively cannot send variable length packets to the miniboard. An example of a variable length packet encoding follows.

void Packets::writeCameraCommand(QByteArray camera_data)
{
    qDebug() << "writing a packet";
    quint8 _packetType = static_cast<quint8>(Types::CAMERA_COMMAND);
    quint16 _crc = 0xFFFF;
    _crc = crc(&_packetType, sizeof(quint8), _crc);
    _crc = crc(&camera_data, sizeof(QByteArray), _crc);
    m_datastream << (quint8)1;
    m_datastream << static_cast<quint8>(camera_data.size() + 3);
    m_datastream << _crc;
    m_datastream << _packetType;
    m_datastream.writeRawData(camera_data.constData(), camera_data.size());
}

You need to calculate the CRC over the packet type as well as the packet data.
