The tmp-webrtc extension lets you transfer files between devices using a peer-to-peer technology, WebRTC.
On first use, tmp-webrtc
must be configured with a unique channel name. Devices having the same channel name will be able to discover each other.
Selecting Send via WebRTC will open a sender window. While the sender window is still open, it will transfer the file to every receiver on the same channel.
In the New item menu, selecting Receive via WebRTC will open a receiver window. It will receive files from any sender on the same channel. That means you can receive multiple files.
