Can Device issue with phoenix tuner

Technical Programming
#1

While we were trying to adjust can devices with phoenix tuner there where no can devices listed it. At the bottom it stated “Lost comm, trying to reconnect to http://172.22.11.2:1339 GeneralError”. we were on the robots wifi and other process were working correctly. We already checked can connection.

To communicate with phoenix tuner over wifi, you need to change the connection type in phoenix tuner. On the main page, enter your team number in the box “Diagnostic Server Address or Team Number”. This should allow you to connect.

We’ve already done that as well as trying usb.

We have had problems when two of the devices currently had the same CAN ID. You could try disconnecting power (pull the fuses) from all devices except one at a time).

#5

In our experience shared IDs cause less showing up not none.

#6

172.22.11.2 is the ip address of the roboRio when connected with USB, so this indicates that phoenix tuner is trying to connect over USB. Make sure that the team number is selected in the drop down.

We used he dropdown and it still errored saying “Lost comm, trying to reconnect to http://roborio-1339-frc.local:1339”

#8

Try changing the port to the default of 1250, that is the defined port for the CTRE server.

#9

Same error with the new port.

What happens when you go to this site?: http://172.22.11.2:1250/?action=getdevices
(Documentation about this is here)
Are you able to drive your robot around?
Has Phoenix Tuner worked in the past?

#11

Can you ping the roborio from the computer you are using?

#12

http://172.22.11.2:1250/?action=getdevices says “took long to respond”

Not sure how we could test if we can drive the robot around without access to check current ports.

Phoenix tuner has worked in the past

Driver station has comms and robot code.

You didn’t happen to format your roboRIO since the last time Phoenix Tuner was working, did you?

Have you installed the Phoenix diagnostic server? If you formatted the rio you will have to do this again.
Is the driver station printing any errors?
Have you driven this robot in the past?

#15

I think we may have.

#16

You need to follow C_MacC’s link then and reinstall the Phoenix server on the roboRIO.
