Device Lookup ARM Jetson Orin

[johnjz30]

I had initial struggles building the executables via Cmake. I eventually got them to build using:
cmake -DLIBHEBI_TARGET_ARCHITECTURE=aarch64 ../projects/cmake
make
I have 4 R8-16+ devices connected to a switch, all of which are connected to the Orin. I can ping each of the 4 servos. I can access each of the 4 servos via Scope on the device that I am SSHing into the Orin with (headless variety).

I am able to confirm via ldd that all libraries are connected. However I cannot get Lookup to find the devices via Family/Name nor Mac address. I copy and pasted the Family/names directly from Scope to avoid typos. Family GIMBAL R8-16+ Name YAW-R8-00575. Any suggestions?

Sorry for the struggles here -- we are overdue for some cleanup on the CMake side to make this easier!

For now, I merged in this documentation fix PR to address this oversight.

For the Lookup issues itself, it sounds like this is indeed not linking related, or you would get a runtime error.

If you build and run the initial lookup example, can you share what is printed out?

If they show up in the printout here, can you share the code snippet you are using to call the lookup object? Otherwise, it would be good to better understand your networking setup. If they are not visible in the lookup, this may be related to the C++ library not being able to find a valid broadcast interface to send lookup packets on.

Thank you for the reply and the additional documentation. After working through the problem from the beginning again and ensuring all the basics were followed, I have discovered that my subnet mask was not the same on the Orin as on the Hebi devices. Making sure everything was 255.255.255.0 allowed the Hebi lookup to appropriately find/communicate with the devices. Thanks again!
