Thanks Wouter, that's the approach I'm leaning towards at the moment.

Casey Offord created a new topic ' Driver for motorized dob' in the forum. 1 month ago

Hello everyone,

I'm working on a homebuilt motorized dob to supplement my refractor and EQ mount. I currently use the INDI drivers for all of my equipment and run everything with KStars/Ekos. I'd like to do the same with the dob. Since I'm controlling the dob motors with an Arduino, I can set things up any way I'd like.

On the RasPi side, I know I can write my own driver and make everything from scratch, but I'd rather use an existing driver and write my Arduino code to suit it. Can you recommend which driver would be suitable for a simple alt-az dob mount?

Thanks,
Casey

I never could get the UBlox 7 dongle working, so I did the same thing and used the GPS in my iPhone with the GPS2IP app. Works great.

Hello everyone! I have an INDI server running on a RasPi 4 that I built up myself (ie, not an astroberry image). It's been working well with the following devices:
Nikon D5600
ASI120MM Mini
EQMod mount
GPSD (UBlox 7 dongle)

I just received a new ASI533MC Pro, so I changed the CCD config in Ekos to the new camera, fired everything up, and the camera is working great. Unfortunately, the GPS no longer works. The device is shown in lsusb, I see it connect in dmesg with no errors, but I get no real messages in gpsmon. If I unplug the camera, the GPS gets a fix in less than 30 seconds, as before. If I have a GPS fix with the camera unplugged, and then plug the camera in, I lose the GPS fix.

Things I have tried:
Updated all drivers
Verified no virtualgps service running
Extension cable for the gps dongle in case noise was preventing reception
GPS dongle on USB2 port with ASI533 on USB3 port
GPS dongle and ASI533 on USB3 ports
GPS dongle on USB2 port with ASI533 on powered USB3 hub
GPS dongle and ASI533 on powered USB3 hub
Burned a fresh astroberry sd card, configured, and recreated the problem exactly as above.

So...I'm a bit stumped. It's almost like an old IRQ error but that shouldn't happen with USB. Any ideas?

GPS attached, with fix, no cam
