How can you display binary data in hex format?

[Cruz]

Hi.

After reading from a serial port I have a bunch of binary data in a char buffer.

char buff[n];
int bytesRead = port->read(buff, n);

char buff[n];
int bytesRead = port->read(buff, n);

To copy to clipboard, switch view to plain text mode 

I want to scrutinize the data byte by byte and display each byte in a hexadecimal format like this: 0x01 0x1F 0xFE ...

Can you please point me in the right direction?

you can use QString::arg() to format a number for any base (16 for hex).
iterate over your bytes and print each that way and you have what you want.
