Open a TCP socket to port 6112 on any of the active BNCS. Send your connection select byte, then go into a net loop on the received data. Beware of partial receipts as well as receiving multiple bncs messages in a single receive operation. Consult BnetDocs for details of the individual packet formats.

Ummm - you mean packets getting scrambled? Didn't ever think of that as a possibility...

Ok, that means I gotta rewrite a part of my bot's connection code

I think he meant a packet that doesn't contain all the information it should, almost as if it had been cut off.

No -- what he means that, Battle.net will sometimes put more than one packet together:

Example: extremely unlikely, but it illustrates the point.
[code]
ff 00 04 00 ff 00 04 00
[/code]

It will also sometimes not send an entire packet with one Receive callback:
[code]
ff 0b 4c 00 (P) (u) (b) (l) (i) (c) ( ) (C) (h) (a) (t) ( )
(U) (S) (A) (-) (1) 00 (O) (p) (e) (n) ( )
[/code]

If you look at the length specifier (sorry, I was too lazy to look up hex codes for all the ASCII chars), you can see that the specified packet is supposed to be *much longer* than the data that was received (0x4c vs 0x1b).

That's what it means. There's no "scrambling" of packet info.

So, more like: I receive a SID_PING, which should be 8 bytes long (1 for FF, 1 for Packet ID, 2 for length, 4 for Ping value), but I only receive 4 bytes - in that case I should wait for the other 4 bytes...

Is it possible then, that I receive 4 bytes for SID_PING, then receive a SID_AUTH_INFO, and then the rest of SID_PING?

My code already properly deals with packets that are "concatenated"

This has to stop, you mods should make a sticky saying before asking this question use the search button and look in the Battle.net Bot Development References before you ask questions.

Thanks if any mods decide to do this.

Yes. No. Therefore, you're ok.

Indeed. You may get part of a packet, a whole packet, or multiple packets clumped together. Those are the situations you have to handle.

Alright, thank you very much

So just to make sure it's clear, you should NEVER receive a partial packet, then another packet before receiving the rest of the partial packet.
