{{outdated|edition=bedrock}}

This article documents the '''protocol''' which ''[[Minecraft:Pocket Edition]]'' used before it was replaced by a [[Minecraft:Pocket Edition protocol|newer ''Pocket Edition'' protocol]].{{when}}

Unlike the {{JE}} protocol, this protocol uses UDP with (so far observed, at least) one message per packet. This makes the protocol easier to work with when it comes to packet serialization, and might offer latency improvements, but will inevitably have the usual UDP issues (packets lost, truncated, duplicated, out-of-order, etc.).

As of [[Minecraft:v0.9.0 alpha]], clients appear to search for servers on only port 19132.

Clients don't pick any specific port to listen on.

Please note that even where packet field names are written in this page, these are still largely hypothetical and could well be incorrect guesses. Some packets are fixed to the [[Minecraft:RakNet|RakNet protocol]], and will be marked as "RakNet Packet", which means that these packets will not change on future versions.

It has been determined that PM uses RakNet for its networking library, [http://www.jenkinssoftware.com/raknet/manual/networkmessages.html some documentation that seems relevant].

Clients start out by sending this packet to the IP broadcast address on port 19132 repeatedly (approx once per second) when joining a server was chosen on the main screen, and stops when the user selects a server (or leaves the screen). The ping ID from the client increases over time, and appears to be the number of milliseconds since the client program was started (might be used to measure server response latency).

If the version is different than yours, reply with a 
[[#0x1A|ID_INCOMPATIBLE_PROTOCOL_VERSION (0x1A)]]

Sent from the client after the player taps on the server in the world list The client will repeatedly send this with reducing sizes until it successfully receives a reply. Observed behavior is that the client will send packets ~0.5s apart in the following way, until it gets a 0x06 response packet, or reaches the end of these:
* 4 packets of Null Payload length of 1447
* 4 packets of Null Payload length of 1155
* 5 packets of Null Payload length of 531
If the server doesnt't reply the client, the client will display a "Connect Error" window

{{anchor|Packet_Encapsulation}}

== Packet Encapsulation format ==
The payload in 0x80-0x8F packets is encoded using different schemes.
To decode them, you've to use the Encapsulation ID to check wich type you should use.
The Encapsulation ID is the first byte of the payload.

Multiple Data Encapsulation packets could be present in one packet. If you want to send data, use 0x00.

<code>Length</code> field is in bits, not bytes. To get the length in bytes, use <code>length_in_bytes = length / 8</code>. The <code>length</code> field is '''excluding''' the header -- both the 0x8X packet header, as well as the encapsulated packet header.

'''Data Array'''

The data array section is unknown, but we do know how to get it right. Below is some code on how to create the array (C#).

   public void putDataArray()
        {
            byte[] unknown1 = new byte[] { 0xf5, 0xff, 0xff, 0xf5 };
            byte[] unknown2 = new byte[] { 0xff, 0xff, 0xff, 0xff };
            this.putTriad(unknown1.Length);
            this.putBytes(unknown1);
            for (int i = 0; i < 9; i++)
            {
                this.putTriad(unknown2.Length);
                this.putBytes(unknown2);
            }
        }

A triad is a 3 byte integer.

'''Data Arrays'''

''Array 1''

The first array is just a series of bytes, starting with the first byte which has the length of the rest of the array. This can be decoded as follows (Java):


   buffer.get(new byte[(int) buffer.get()]);


The buffer variable is really a <code>ByteBuffer</code> object found in the package java.nio.

''Array 2''

The second array is a little more complicated. The first section is a triad (3 bytes) which specifies how many bytes to read next. This is repeated 9 times. An example is below (Java):


        for(int i = 0; i < 9; i++){
        
        	int l = NetworkUtils.getTriad(buf);
        
        	buf.get(new byte[l]);
        
        }


Again, the buf object is a <code>ByteBuffer</code> object.

This appears to be sent whenever the user clicks the "cancel" button when connecting.

== Ping/Pong ==
The client will repeatedly send ping packets to the server each containing an identifier (long). The server then must reply with a pong packet containing the identifier found in the ping. This is observed to happen sometime during the encapsulation login.

This information has been generated using [https://github.com/PocketMine/PocketBurger PocketBurger], then edited manually.

'''This information was generated based on:'''

'''Minecraft: Pocket Edition v0.7.3, protocol #11'''

'''RakNet Protocol version #5'''

However, these packets seem to be unchanged since then, and will (most likely) work with the current version.

'''Minecraft: Pocket Edition v0.10.4, protocol #20'''

The three type of status are:

1: If the server is outdated.
 
2. If the game is outdated. 

If everything is good you need to send StartGamePacket.
