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.).
As of 0.9.0, 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 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.
The login sequence is not covered by this page.

Login Packets
All packets start with a single byte that identifies the packet type, the rest of the packet follows it. Please note that packets 0x09 through 0x13 are not documented (yet).

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 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 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

Encapsulated Login packets
After packets 0x05 through 0x08 are sent, the client will send the first encapsulated packets (0x09 through 0x13). After 0x13 the game begins. You can check the login sequence here.
Client Connect (0x09)

This is a Data Packet. It is encoded using packet encapsulation (scroll down for more info).

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.

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
