sending socket data as hex?

[horst]

Hi,

with send() I can only send strings, right? But I want to send hex data, how can I do this?

My sample code:

import socket

host = '192.168.4.2' # laptop running server
port = 2004
addr = socket.getaddrinfo(host, port)[0][-1]
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(addr)
s.send('ffff') <- at this point I don't want to send ffff as text but as hex
s.close()

You should use binary data.

For binary use the following format.
s.send(b.'ffff')

For hex:

import binascii
s.send(binascii.hexlify(b'ffff'))

Or do you want this?

s.send(int('0xffff', 16))
