json-server terminates under MacOS X Sierra

[FellMel]

After I've updated my OS to MacOS X Sierra, the json server terminates after sending a few commands to tinyg.

I suppose it's a problem with the USB communication.

On the JSon server console, I get following output:

I have the same problem. I popped into the garage to cut a file on my CNC router, and came up against this. It will stay connected for various (short) periods of time. I can restart Serial Port JSON Server, and it'll happen again in short order.

Check out the Github release page for SPJS. I just uploaded the binary that FellMell created.

Try this newly compiled binary that FellMell created. He compiled it on the latest Mac OSX and he said it works.

Awesome! I'll try it out when I get home again!

Any information about what the problem might have been or what was changed in the new version?

[FellMel]

I've only build the last sources and not really testet it, yet. But a first short tests looks fine. Maybe it depends on an update of the golang compiler or on XCode.

I plan an intensive test at weekend.

[Snortimer]

Well, whatever it was, it seems to work now!

Thanks!

[FellMel]

I've tested it, too. No problems in a 2 hour job.

I think, it was an incompatible linked library, which was fixed by the fresh build.
