send binary file over serial port with QSerialDevice

[marcvanriet]

I'm not able to send the stream to the serial port.

Do you mean nothing is transmitted over the serial port ? Or only part of the datastream ? Or is your problem on the receiving side ? What do you have on the receiving side ? Another computer or some sort of electronics device ? If you connected it to another com-port, you can check with any 'hyperterminal' application if something is received. An oscilloscope may help to check what is transmitted also.

If you create a small QByteArray with readable text in it, and then use "qint64 write(const QByteArray &byteArray)", does it get sent or not ?

Best regards,
