WriteData Method

Sends data to the remote peer through the negotiated candidate pair.

Syntax

procedure WriteData(const aText: string);

Name	Type	Description
`aText`	`const string`	UTF-8 payload to transmit to the remote peer.

Routes the supplied payload through the candidate pair that was nominated by ICE. The transport chosen depends on the remote candidate type:

Host / Peer-Reflexive / Server-Reflexive — the bytes are sent directly to the remote IP and port; if DTLS is enabled in RTCOptions.DTLS the payload is encrypted first.
Relay — the bytes are relayed through the TURN server, using the existing channel binding (SendChannelData) when available or an indication otherwise.

Call WriteData only after OnRTCConnect has fired; writing before a candidate pair is nominated is silently ignored.

procedure TForm1.oRTCConnect(Sender: TObject;
  const aCandidatePair: TsgcICE_CandidatePair);
begin
  oRTC.WriteData('Hello peer!');
end;
