QDriverStation unable to establish connection with roboRIO #39

Closed primetoxinz closed 7 years ago

primetoxinz commented 7 years ago

Specs: Arch Linux 4.7.6-1 QDS Commit 9393cc2 built from the AUR RoboRIO Firmware: unknown currently, likely last 2015 version

Today I tested connecting to the roboRIO with QDS for the first time. The wireless connection was successfull and the roboRIO web dashboard (10.17.93.1) works perfectly. Launching QDS there is an attempt to connect to roboRIO-1793-FRC.local and no other output Attempted changing the mDNS to the static ip of the roboRIO (10.17.93.76) still no change Tried the official FRC DS on the provider FRC laptop, immediately established comms.

This is either an issue with QDS or my networking setup, any ideas? If any info from the roboRIO is necessary I won't have access until this wednesday

I would suggest looking at the log file(s) in '~/.qdriverstation/'

here is the log for the first attempt to use QDS

bman12three4 commented 7 years ago

Just to piggy-back on this, this occasionally happens to me as well. The solution for me is to delete the app from my computer and reinstall it, and that works for a couple more times.

primetoxinz commented 7 years ago

hopefully will be able to try the reinstall trick tomorrow, would still be nice to know the cause of this and possibly find a fix, if it does work.

BearzRobotics commented 7 years ago

It looks like first a problem with the QNetworkReplyImplPrivate. Second it looks like a hex value is trying to be read as a function.

Third this right here looks like QObject::disconnect needs a parameter but non was given. "QObject::disconnect: Unexpected null parameter"

I believe this is the underlying problem. Tomorrow i will email Alex

directly to get his attention.

Sorry for the late response, I just got back from school right now.

There are several possible causes for your issue:

I think that the main problem is that your custom address was never used by the QDS (judging on the log file). Try clicking the close button on the preferences window after imputing the robot's static address.

Hopefully this will fix your issue!

primetoxinz commented 7 years ago

I input the static ip and pressed closed and immediately got coms. Would prefer if the mDNS worked, but as long as it functions

alex-spataru commented 7 years ago

@primetoxinz Glad you've got it to work. Getting mDNS to work on every OS is not so easy, even when the QDriverStation has its own fallback implementation of mDNS. Hopefully one day we'll be able to make it work seamlessly 👍
