Hi all. Has anyone experienced flaky connection from DriverStation to Rio1? It seems to be frequently flapping from connected to not connected, for no apparent reason. It’s often solved by renewing DHCP connection or restarting the Rio. It doesn’t seem to be a physical network problem, because I can ssh into the rio and don’t get disconnected. Any ideas or suggestions would be greatly appreciated!
SSH is a TCP connection and not subject to the same timing/latency requirements as the DS is trying to hold. What is your network setup (eg wifi, is it 2.4 with one radio or 6 with two), does it happen when tethered, etc?
In addition to Peter’s questions, given that you’ve also been having memory issues and changing OS parameters, does this happen on a freshly imaged roborio running example code?
Since many things could cause disconnects, need to isolate. There’s additional things to look at here: Known Issues — FIRST Robotics Competition documentation
You might be having interface with your current WiFi setup. Try and whitelist your radio from your network and see if that helps with your connection issues.
What do you mean by this?
We previously had an issue where we would lose comms with our bot whenever we enable. We then sent the MAC addresses of the radios to our District’s IT department to whitelist the radios, we never had a problem since.
Interference?
By interference, I mean network restrictions or blocks. Whitelisting the MAC addresses with IT ensures the network allows uninterrupted communication between the driver station and robot.
Unless it’s a managed windows education install that shouldn’t be a problem
I don’t know what to tell you. We are using a regular version of Windows and when we whitelisted everything, we had no issues since.
