- peerHandle
- PeerHandle
The peer's handle for the message. Must be a result of an
DiscoverySessionCallback#onServiceDiscovered(PeerHandle,
byte[], java.util.List) or
DiscoverySessionCallback#onMessageReceived(PeerHandle,
byte[]) events.
- messageId
- Int32
An arbitrary integer used by the caller to identify the message. The same
integer ID will be returned in the callbacks indicating message send success or

Remarks
Sends a message to the specified destination. Aware messages are transmitted in the context of a discovery session - executed subsequent to a publish/subscribe DiscoverySessionCallback#onServiceDiscovered(PeerHandle, byte[], java.util.List) event.
Aware messages are not guaranteed delivery. Callbacks on DiscoverySessionCallback indicate message was transmitted successfully, DiscoverySessionCallback#onMessageSendSucceeded(int), or transmission failed (possibly after several retries) - DiscoverySessionCallback#onMessageSendFailed(int).
The peer will get a callback indicating a message was received using DiscoverySessionCallback#onMessageReceived(PeerHandle, byte[]).
