Build successful, but driver station's app doesn't get the code

We are having problems to share the code with the driver station’s app, the build is successful, but in the driver station’s app there is “NO ROBOT CODE”.

(We are using a Command based code)
(Time based is working)

If communications light is green (it’s above where it says NO ROBOT CODE), there is likely an error with the code. In the text box to the right of the NO ROBOT CODE on the driver station do you get an error message?

We don’t get any error message


Hmm, is there any way you can post your code online, like to a git hub?

Also would recommend getting a new battery, that battery is nearly dead.

Did you deploy the robot code?
If yes, try restarting the RIO through driverstation. Those are my quick first guesses.

Your code is likely crashing on startup.
Take a look at the console output viewer:

  • In the Driver Station app, click on the gear to the right of your team number and select “View Console” to get messages generated by your code starting up on the robot.
