# RakNet.send

> Queues packet data for the RakNet send path. The packet can be a string, buffer, array table of byte numbers, RakNetPacket, or RakNetPacketTable. Raw data calls may also pass optional priority, reliability, and orderingChannel values. The call returns no values.

<div className="real-function-page">
  ```lua theme={null}
  RakNet.send(packet: string | buffer | {number} | RakNetPacket | RakNetPacketTable, priority?: integer, reliability?: integer, orderingChannel?: integer)

  ## Exemple

  Queue packet data after checking that the RakNet API surface is enabled.

  ```lua theme={null}
  if RakNet.is_enabled then
      RakNet.send({ 0x83, 0x00 }, RakNet.PacketPriority.MEDIUM_PRIORITY, RakNet.PacketReliability.RELIABLE_ORDERED, 0)
  end
  ```
