Heads up!

This article is about the protocol for the latest stable release of Minecraft Bedrock Edition (1.14.60, protocol 390). See Protocol for the Java Edition Protocol.

This is the Bedrock Edition Protocol Documentation. The Bedrock Edition Protocol uses UDP instead of TCP that is used for the Java Edition.
The Bedrock Edition Client uses RakNet as its protocol library.

The default Bedrock Edition port is 19132

According to the NukkitX Protocol, the server sends the Y coordinate divided by two, and negative if needs to be subtracted by one. Example:

   int y;
   if (packet.getBlockPosition().getY() > 0) {
       y = packet.getBlockPosition().getY() * 2;
   } else {
       y = (packet.getBlockPosition().getY() * -2) - 1;
