how to process hexadecimal

[high_flyer]

Do you mean something like this?:

if(comport->bytesAvailable())
    {
        long count =comport->bytesAvailable();
     QByteArray comdata=comport->read(count);
        //comdata=comdata.toHex();
        //qDebug()<< comdata;
   for(int i=0; comdata.size(); i++){
        qDebug()<<"data[%d] = "<<i<<" %x"<<comdata[i];
     }
}

if(comport->bytesAvailable())
    {
        long count =comport->bytesAvailable();
     QByteArray comdata=comport->read(count);
        //comdata=comdata.toHex();
        //qDebug()<< comdata;
   for(int i=0; comdata.size(); i++){
        qDebug()<<"data[%d] = "<<i<<" %x"<<comdata[i];
     }
}
