Re: How to send a sequence of bytes

Renaud,

Curious. I tried that but it literally sent the string 0x31,0x00,0x30,......etc rather than the actual hex bytes represented by string.
I have attached the Wireshark screen grab.

Here is my code.

pktdata = '
0x31,0x00,0x30,0x00,0x33,0x00,0x3b,0x00,0x38,0x00,0x36,0x00,0x3b,0x00,
0x31,0x00,0x2e,0x00,0x30,0x00,0x2e,0x00,0x30,0x00,0x2e,0x00,0x30,0x00';


port = 15000;
soc = open_sock_udp(port);
if (soc) {
  send(socket:soc, data:raw_string(pktdata));
}
r = recv(socket:soc, length=1024);
if (r) display ("Response received\n");
close(soc);

You'd do :

send(socket:soc, data:raw_string(0x31, 0x00, 0x30, ....., 0x2e, 0x00,  
0x30));
