I'm trying to develop an Arduino equivalent of the SQM-LU. The serial number (response to ix request) is coming through fine, but I'm not seeing the sky magnitude reading coming through. I expect I have a logic error in responding, but the logic is identical to the ix request for the rx request. These are the only two requests I am responding to at the moment.

Has someone else already gone over this hurdle so I can adapt their code? If not, where can I peruse the INDI SQM code? (I can't seem to find it on my own.)

Thanks,

Richard

I reviewed the documentation and realized that I also needed to check for Rx. I'm getting communications with INDI about other errors now . That's progress .

I now have a working prototype . I'll post code to GitHub and enclosures to Thingiverse when I get all flanged up.
