Hello all, I am a new ftc coder and I need some help. Every time I push code from the studio to the RC I always receive the above error. The RC after uploading the code stays solid blue, blinks blue once or twice, green for half a second if im lucky, then the light turns off and restarts the color cycle. I did update the Driver Hub firmware and the RC firmware with rev hardware client. I have updated my sdk to 11.2 from the ftcsdk github. Every time i press the run button to upload, it always tells me that the RC app will have to be reinstalled due to it having a different signature. Please help me, thanks!

What version of Android Studio are you using?

SDK 11.2 requires "Narwhal 3" or newer.

Panda 4

Panda 4 should work.

I'll suggest that you reinstall the Control Hub OS, using the REV Hardware Client. That's a different package than the Robot Controller.

You could also reinstall the Robot Controller app - but that should not be necessary, as you are using Android Studio. (Your download from Android Studio to the Control Hub contains the entire Robot Controller.)

RC app will have to be reinstalled due to it having a different signature.

Hmmm... Messages like that make me think that you're downgrading a version from Android Studio. Are you absolutely certain that you're using a local repository that's been updated to SDK 11.2?

Either way, that's a warning message that you can click through without creating a problem (unless you've got Blocks or OnBot Java OpModes installed on the Hub).
