Pocket Minecraft Protocol
Unlike the Minecraft 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.).
Servers listen on UDP ports 19132-19135.
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 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, some documentation that seems relevant.

Packets
All packets start with a single byte that identifies the packet type, the rest of the packet follows it.

| MAGIC | MAGIC | |||
| Total Size: | 25 Bytes | |||
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 ID_INCOMPATIBLE_PROTOCOL_VERSION (0x1A)
Sent from client after it receives packet 0x1d. The client will repeatedly send this with reducing sizes until it successfully receives a reply. Observed behaviour 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

Minecraft Pocket Edition v0.5.0.0 introduced another identifier special for Minecon 2012 "MCCPP;MINECON;". This will show a Minecon logo in front of the server name, and the color of the name is changed to blue.

Sent after a 0x8X. It's used to ACK recieval of packets. The second packet number is optional and only there when bool is false.
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
Calculate length in bytes:
real length = length / 8
