These will be imported as a single packet. Select None when only the bytes are present.

With a leading 0x or 0X offset is interpreted as a. It is a wrapper over the Message Debug standard GNU Radio block, so it uses the same output format. By default, offset is interpreted as a decimal number. The hexdump sink prints PDUs in hex to the standard output. Skip offset bytes from the beginning of the input. I also have a command line version of hexdump that you can download and run. It is useful for seeing exactly what is in a file, byte-by-byte. However, the od command also has options(-x) to do the hex dump of a file and the output is in big endian format: Two-byte octal display Display the input offset in hexadecimal, followed by eight space-separated, six column, zero-filled, two byte quantities of input data, in octal, per line.
