Error: unable to set BinningHorizontal to 1 (ptr retrieval)

edit

hi,

Ubuntu 18.04, ROS Melodic

I have installed the spinnaker_sdk_camera_driver as described in the readme file, but run into following error(s) when launching the acquisition.launch file:

[FATAL] [1568200173.896803656]: Unable to set BinningHorizontal to 1 (ptr retrieval). Aborting...
[FATAL] [1568200173.897091343]: Error: Spinnaker: GenICam::AccessException= Node is not writable. : AccessException thrown in node 'BinningHorizontal' while calling 'BinningHorizontal.SetValue()' (file 'IntegerT.h', line 77) [-2006]
[WARN] [1568200173.897146015]: Most likely cause for this error is if your camera can't support color and your are trying to set it to color mode

log file: /home/dflap3/.ros/log/9f133bc8-d484-11e9-a8db-704d7b468a87/acquisition_node-3*.log

both cameras are recognized and stated as "connected" in the output.

I have set HorizontalBinning to 0, and this is also stated in the output under parameters:

* /acquisition_node/binning: 0

also color mode is deactivated, even though the cameras (BFLY-PGE-23S6C-C) do support color.

Any suggestions?

Thanks a lot and best regards, addext
