I have been able to test that this doesn't crash. However, since I don't have a camera with a serial port, and I can't connect a loopback cable to the cameras as the instructions say from the virtual loan tool, I'm afraid I'm stuck. Are either of you interested in finishing this example? @guoxe @kjughx

Are either of you interested in finishing this example?

As in continuing development or just test if it works?

[apljungquist]

If it compiles, it works. Right? 😅

More likely it will need a few test-fix cycles, so I was thinking the same person would do both to avoid slow handovers and context switching. If it doesn't sound like fun, maybe you know someone who is interested in taking a Free(ky) Friday to learn ACAP/Rust...

I'm eager to help us much as I can, be it by doing the development, pair programming or just answer questions. And I'm not partial to what I built, I only want a PoC for the last API.
