Talk:Pocket Minecraft Protocol

Got 0x1c when I sent 0x02 to a server

I've been playing around with this protocol and acting as a connecting client, I found that the protocol seems to be different than what is listed on this page. I sent these hex values to my iPod running Minecraft PE (full) v0.1.2 alpha: 02 00 00 00 00 00 a1 a2 41 00 ff ff 00 fe fe fe fe fd fd fd fd 12 34 56 78. It replied with 1c 00 00 00 00 00 a1 a2 41 00 00 00 00 79 1b 2d 6d 00 ff ff 00 fe fe fe fe fd fd fd fd 12 34 56 78 00 0b 4d 43 43 50 50 3b 44 65 6d 6f 3b 00 00 00 00 00 00 or 1c 00 00 00 00 00 a1 a2 41 00 00 00 00 79 1b 2d 6d 00 ff ff 00 fe fe fe fe fd fd fd fd 12 34 56 78 00 11 4d 43 43 50 50 3b 44 65 6d 6f 3b 6f 78 67 75 79 33. This is almost exactly like 0x0d, but it's got a different ID - 0x0c.

Here's a more readable way of writing this. I sent:

• int8 = 0x02 (packet type ID)
• int64 = ping ID
• MAGIC

The server replied:

• int8 = 0x1c (packet type ID)
• int64 = ping ID from client
• int64 = unknown (server ID??), 00 00 00 00 79 1b 2d 6d
• MAGIC
• int8 = 0x11 is server is visible, 0x0b if server is invisible
• the string "MCCPP;Demo;username" (username is omitted if invisible)

Make of this what you will. I'm hoping to do more protocol analysis with two devices running Minecraft PE soon. -Oxguy3 20:58, 1 December 2011 (MST)
