Unable to connect camera Basler TOF with pylon_camera
Hi, I am using a Basler camerawith ethernet cable and changed the IP of the camera. In the pylon SDF, I have to set the IP of the camera to find it. How can I do it in the ros driver pylon_camera?
Here is what I get when I don't set the IP:
$ roslaunch pylon_camera pylon_camera_node.launch

Does "Device is not an U3V device" means that the driver works only with USB connection?
When I run /opt/pylon5/bin/PylonViewerApp to see the output of the camera, I only get a black screen, and the lights of the Basler camera don't light up. Any idea? What am I doing wrong?
EDIT My MTU was too small then the jumbo frames didn't pass. I increased my MTU to 8192 and now I got a screen without image in the PylonViewerApp, and the lights of the Basler camera still don't light up. In the terminal I still get:
GetDeviceDiscoveryInfo: bFunctionClass = 14, bFunctionSubClass = 3, bFunctionProtocol = 0. Device is not an U3V device.
The output of the Grab is:
SizeX: 666
SizeY: 738
Gray value of first pixel: 0
SizeX: 666
SizeY: 738
Gray value of first pixel: 1
That seems that the image is received somewhere, right?
When trying to launch the ROS driver, I get now:

[pylon_camera_node-2] process has finished cleanly
IIRC, the GigE protocol doesn't use/need IPs, as the local subnet is scanned for compatible devices. You then typically select one of those by specifying a serial nr or device ID. The
config/default.yamlfile in thepylon_camerapkg has adevice_user_id, which you should be able to use.Whether the package is then compatible with your camera, I can't say. The Magazino devs frequent this board, so I expect one of them will respond. Alternatively, you could post an issue on the issue tracker.
Hi, thanks for your answer. I set the device ID in the parameters, but I get the error that I posted in my question
Could you give us some more information? Which camera are you using? Which IP have you assigned and how does your network look like? Can you get images with the PylonViewerApp? Do you have several cameras attached? It's nice to see our package in use :)
Based on:
I would say that, no, the PylonViewerApp also doesn't work :)
Oops. Didn't see that. In this case, the problem is probably not in the pylon_camera but in the setup of the camera. Is the camera at least listed as a GigE-Device in the PylonViewerApp?
Hi, I updated the question. I had an error of MTU
What camera model do you use?
