@Alex-Kushleyev Thank you very much for the solution, I fix it and it works. : )

@tom Thank you very much, I got it.

@tom The serial number is M22000006H2, please check the picture for more details. By the way, this rb5 bought in Sep. 29, 2023.

@Moderator Thank you very much for your suggestions. Currently, I install the latest version 1.1.2. And everything looks back in normal.
However, in the process of installation, I met some errors and I did not know whether it is a big issue.
Also, I found my original file miss some file : "opencv_stereo_intrinsics.yml" and "opencv_stereo_extrinsics.yml", can you send them to me.
Please check the pictures for more details:

@tom Thank you very much for your guiding. It works.
However, I got another issues about the camera. I follow the instruction How to Connect VOXL to QGroundControl over WiFi
, but my rb5 did not have any video showing in the QGC. And I run the voxl-inspect-services and found voxl-streamer did not run. Moreover, my rb5 software might be an old version since I can not find the command like: voxl-inspect-mavlink. Can you give me some suggestions?

please check the below picture:

Thank you very much for your help and support.

@tom Yes, the macbook and rb5 both connected to the hostpot. By the way, I installed the macbook with Ubuntu 22.04 not MAC OS.

I did not use the voxl-wifi station SSID PASS on the rb5. I just follow the link text.

Can you guide me how to do that?

Thanks.

@tom So, what should I do for the next?
How to setup it?
The network I used is TModile 5G in the Ipad and I turn on the hotspot to connect the rb5 and the host PC.

@tom Sorry, I want to update something.
I can ping 127.0.0.1, but I can not ssh it. please check the picture:

Thanks.

@tom My host PC system is ubuntu 22.04, is that an issue? since I looked at the instruction which suggest 18.04.

Thanks

@tom Thank you for your reply.

I list the full output of ifconfig, can you help me figure out which IP I need to use in the ssh? I tried 127.0.0.1, it also did not work.

Thank you very much for your help and support.
