Does anyone know if there is a driver for the USB version of the SQM
www.teleskop-express.de/shop/product_inf...nfo/p3793_Sky-qualit sery-meter--lens-version--with-USB-connectivity.html


I see there is a driver for the one with the ethernet link
www.indilib.org/devices/auxiliary/sky-quality-meter.html

If not, would anyone know about the serial protocol? I'm interested in getting one of these.
Thanks,
Derek

I'd imagine it uses the same protocol. If that's the case, then only a simple modification to to the existing driver is required to make it use USB. But I only implemented a minimal driver without all the features supported by the protocol.

Yes it looks like it is. I asked Anthony from the company that makes them. The protocol is published openly. I'm thinking of getting one. If I do I'll submit a PR for the driver changes.

I got my SQM-LU yesterday and just started looking at the existing driver.....

I'm thinking of changing the existing driver to extend both the TCP and Serial (is this possible?) and let the user choose the connection in the options .

Is there any example of an existing driver that has both TCP and Serial?

Thanks,
Derek

There is really no difference, you just get a file descriptor in both cases that you write to and read from.

Thanks Jasem,
I think I'm struggling with something more basic :-)
Like how to add the Serial class as well as having the TCP class in sqm.h...
namespace Connection
{
class TCP;
}

I'll hack around with it later and see how far I can get.

It's trivial, check how inditelescope.h is doing it. same thing.
