Some config & Errror encountered from the ROS driver

[yulan0215]

Hi:

I used this ROS driver and did some Configuration, however, I still have this kind of problems shown below:

[ WARN] [1695583457.816216763]: Feature DeviceTemperatureSelector: value unavailable ERROR Invalid value.

Sometimes I could not open the camera and I did not know about the warning: Feature DeviceTemperatureSelector: value unavailable ERROR Invalid value. Either... I used the pulse from GNSS receiver to trigger the camera.

I also got the ERR like: ERR: FrameObserver VmbFrameStatusIncomplete, I did not know how to overcome those problems. Besides, I also have the problems like the time stamp, I used the mono_camera to launch my 2 cameras, sometimes they worked but the header were different, camera 1's header time was 0.2 second ahead of the camera2's. Do you have any idea about this also? Thx
