Re: Intermittent connection on field only

A few more data points.

This does happen while setting up prior to a match also, while the robot is disabled. We set the robot out on the field, it links up, and then it will randomly lose connection while other robots are being set up.

We are using the camera connected directly to radio. All the code to access the camera on the robot is disabled.

We have customized the dashboard, and our using our own laptop. However the issue occurs on two different laptops. Driver Station CPU utilization is low. We are not using the kinect or the cypress board. cRIO CPU utilization is around 50%, but this happens with the default LabVIEW code also.

We've had two CSA's, the Field Supervisor, and the FTA all look at both the robot and the field logs, without any obvious answers, the robot just loses communication.

There is no correlation with battery voltage as seen in the FMS logs or the DS charts tab. (unless something is happening too fast to see). It happens with multiple batteries.
