As shown in this thread, another team has had issues with communicating with the roboRio. We tried hitting the reset button on the roboRio and it fixed the issue. However, we will need to do this each time.
This still appears to be a hardware issue with the radio. The only solutions that other people have been posting are to check a bunch of diagnostics. However, maybe more of these issues are due to a radio hardware issue.
We are still waiting for a better solution, because this issue has not occurred before this year.
As well, I have sent an email to AndyMark about this issue.
