Regarding ... Getting Find-Object to interface between an RPI-4 board and a laptop, using TCP across my wifi network
Thank you for your helpful reply.
Yes , I have studied the examples you helpfully provide , but ... unfortunately I'm not experienced enough to figure out some of the details.
I had an idea ... in order to ' keep it simple ' and learn how to get Find-Object to work between machines..
I decided to try to get it working between 2 Windows 10 machines first !
So ... here is my initial set-up;-
Laptop A is a 64 bit windows laptop, with Find-Object version 0.6.0 installed. On my wifi network, its IP address is xxx.yyy.zz.07
Laptop B is a 32 bit windows 10 laptop , with Find-Object version 0.4.4 installed. Its IP address is xxx.yyy.zz.05 .
Note 1 ) Find-Object version 0.4.4 is installed on this machine
The 2 laptops can ping each other, so that aspect of networking is OK
Find-Object works on each laptop stand-alone. I have captured a picture of a coffee mug and can get each machine working alone in the standard GUI mode to detect that mug.
On the 32bit machine I notice that some of the exe files in the bin folder are different to the file names shown on the web-page.
I see the following 5 exe files in the bin folder on the 32 bit machine ( along with many other files ) ;-

So ... here is the set-up I have tried;- With a USB camera connected to the 32 bit laptop
I have stored a photograph of the coffee mug in the /bin folder (the photograph file is named mug2.png ) on the 64 bit machine
When I use command on the 64 bit laptop
Find-Object.exe --console --object box.png --config "" --General/invertedSearch false --Camera/6useTcpCamera "true" --Camera/8port 5000 --General/port 6000 --General/autoStartCamera "true"
That runs

And then I run the command on the 32 bit laptop ...
find_object-imagesTcpServer.exe -p 5000
That laptop says “ Images server waiting on "169.254.203.127 : 5000"

But ... when I present the coffee mug in front of the camera on the 32 bit machine ... nothing happens.
What am I doing wrong ??
Q 1 ) Can Find-Object network between a 64 bit windows 10 and a 32 bit windows 10 machine ?
Q 2) What .exe file needs to be run on each machine ?
Q 3 ) Looking further , later , after it works between windows machines ...what specific.exe file would I have to download to a Raspberry pi 4 board ?
Many thanks for your great help on this Find-Object topic. I'm sure many other people would be interested in getting this working. Find-object is a valuable introduction to this subject, along with your more advanced RTABMAP solution ( for 3D applications ).
Please let me know,
Thanks
