Just WebRTC

A very simple example of how to use WebRTC in 3 steps

Step 1

Give permission

Step 2

Instead of signaling server is used broadcasting
Usually it's enough to connect both devices to one wi-fi access point
For the emulator will have to play around with the settings

Step 3

Wait up to 20 seconds
If the ip address was determined WebRTC will show the magic
If not, specify ip address manually in the partnerIp field
