This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The read-only RTCDataChannel property maxRetransmits returns the maximum number of times the browser should try to transmit a message before giving up when in unordered mode, as set when the data channel was created, or null, which indicates that there is no maximum. This can only be set when the RTCDataChannel is created by calling RTCPeerConnection.createDataChannel(), using the maxRetransmits field in the specified options.
This value is only used while in unordered (sometimes called "unreliable") mode; that is, if ordered is false.
Syntax
var tries = aDataChannel.maxRetransmits;
Value
The maximum number of times the browser will try to send a message before giving up, or null if not set when RTCPeerConnection.createDataChannel() was called. The default is null.
