GRIP errors

Technical Programming
1

I have tried to get grip working with my axis camera. It is setup at “axis-camera.local” on my roboRIO and the new radio. GRIP works on the computer(I can see the camera and all the functions dont have red triangles) but when I deploy it to the roboRIO i get lots of errors!

My common sense would make me think that the camera isn’t displaying frames, but I can clearly see the feed from the camera on my computer when plugged into the roboRIO via usb or the wireless radio! Has anyone else had a similar problem? Any advice on what to try?

2

Deploying GRIP currently does not work with axis IP cameras.

3

It’s possible that that could happen if GRIP can’t connect to the camera, although in that case I think you would also get a “Connection refused” error.

Can you check if you can ping the camera from the roboRIO?

4

I’m on my phone right now, but I’ll check for the ping later. If the grip is getting refused by the axis Camera what can I do to fix that? Do I need to sign into the camera and add an lvuser profile to the access? I already have the anon login enabled, but does it need a different type of access? Should I set the camera to a static IP? Right now I use mDNS.

5

If it works on the desktop, it’s probably not an authentication problem. More likely just an issue with the network setup, although the particular stacktrace you got is kind of weird for that sort of problem.

6

Well I can in fact ping the ip camera from the PC while connected through wifi and roborioUSB. I changed the setup to use the static IP i assigned through the GUI of the camera(10.28.47.10) and I tried just running a GRIP that all it does is PUBLISH VIDEO and it still errors out.
