Driver Station cannot connect to cRio

The DS expects and sets a .5 address on the wired interface.

It sounds like communication may be going from the DS -> the cRIO but the status packets may not be coming back from the cRIO. This would likely be a firewall issue.

I've had success using different IP address than the 'official' address.

However, I did try setting the team number in the driver station and telling it to configure the network device. Didn't fix it.

But then why did the virtual DS work correctly?

Also, the Driver Station software asks for administrative rights -- presumably this is because it needs to disable the firewall appropriately. I can try disabling the firewall however, that might fix it.

... just looked at my firewall config, apparently I had the driver station set to be allowed on 'private' networks, and disallowed on 'public' networks. Or something stupid like that... GRR.

Can someone add something to the driver station software to check to see if it's being firewalled so that way it can warn the user? After all, it does ask for administrative privileges.

It was the firewall. Sigh.

I'll look into it. The DS calls netsh to request that the firewall allow through various programs, but I suppose it could have forgotten itself, it could be getting an error, etc.

Just a bit more background. The terminology of the Robot Comms is a bit confusing, as it really means that the DS isn't receiving the expected information from the FRC Communications library on the robot. This could be for many reasons, and the diagnostics tab can ping for you and show if that is the issue.

Also, the DS IP is not that important for development. After all, it is very convenient to have dev tools on other computers along with a copy of the DS. But I'm pretty sure that the field looks to talk to the DS at 10.te.am.05.

the field looks for .6 as of this year, but if using the lite FMS, it looks for .5

Once again, the DS automatically sets .5 when using the NIC Selection Dialog and that is what the field looks for the DS at.

"In the IP address text box, if this computer is the Classmate and you have run the Driver Station software and successfully set your team number, you should see 10.xx.yy.5, where xx corresponds to the first one or two digits of your team number and yy corresponds to the last two digits of your team number. If this is not the classmate PC you should set the address to 10.xx.yy.6 as the Driver Station defaults to 10.xx.yy.5 for its IP address. In this text box, change the final digit .5 to .6."

this is a quote from:

I apologize, I was misreading the documentation. it is the .5 adress for the classmate. my bad.
