Re: Router/Camera/SmartDashboard issues.

We will be limited to 7Mb/s bandwidth this year, unlike last year which had no limit.
There is also Quality of Service implemented that guarantees command packets (& pings) will get through, but excess video packets will get dumped.

Communication between the ROBOT and the OPERATOR CONSOLE is restricted as follows:

B. Bandwidth: 7 Mbits/second
That means you cannot run your camera at full resolution/no compression/30fps. (~15Mb/s)

The default Dashboard is setup with monitor tools that let you play dynamically with the camera image to perfect the resolution/fps/compression that fits your need.

The reason you are running into this problem wirelessly is that the FRC Bridge Configuration tool setup the DAP-1522 to have the same limits as the playing field will have. That way you can see this problem now rather than being surprised by the limit when you get to the competiton.
