Hi Gerryr,

thanks for your exhaustive reply! I did benchmark my direct wifi connection using

iperf
and it turned out to be approximately 45 Mb/sec over a distance of less 2 meters. I am not planning to take my Mac a long distance away from my scope anyway. Just being able to sit in my car or at picnic table while the scope is taking pictures will be enough. If my Mac had an ethernet port, I would have definitely be using a cable to connect to the RPi. In the beginning, both my Mac and the RPi were connected to my home WiFi router for testing, and I only got a top speed of 9 Mbit/sec. Now it makes sense in the light of your explanation, as the router is downstairs and there are a few walls in between. That's what made me go for a direct WiFi.

Kaczorek, I think I have never really considered running KStars/Ekos locally on a RPi3, as I thought it would be too demanding for that small thing, but apparently it's not! How smoothly does KStar run on a RPi3? I should definitely give Astroberry a try.

Thanks!

Maurizio

Thanks for your quick reply!

I do use KStars on my Mac and I use VNC to connect to the RPi, which anyway has a touchscreen so it's fairly easy to start and control applications. I will give it a try and see how it works!

Would you also suggest stopping VNC while acquiring/guiding?

Thanks!

Maurizio Baldassarre created a new topic ' PHD2 on RPi3 running INDI Server?' in the forum. 2 weeks ago

Hi everyone,

I am running INDI server on a RPi3 to which I connect from a MacBook Pro. The connection between Mac and RPi3 occurs through an ad-hoc WiFi connection. I would like to use PHD2 for guiding as I found it gives the best results with my mount, and I was wondering which option be the best, quickest and most accurate between the following:

1) Running PHD2 on my Mac;
2) Running PHD2 on my RPi3;

My main focus is to get quick and reliable guiding, but I wonder whether a direct WiFi connection is fast enough for the data to be sent from the RPi3 to the Mac, processed, and sent back the mount.

Regarding option no. 2, would it suffice to enter the Pi's IP address in the Host field?

Do you guys have suggestions you would like to share?

Cheers,

Maurizio

Maurizio Baldassarre created a new topic ' Logitech webcam won't work with indiserver on a RPi3' in the forum. 2 months ago

Hi everyone,
I have the following problem: I own a Logitech B525 webcam which I use a guider in Ekos. Everything works perfectly when I run it locally on my laptop. However, when I try to connect everything to my RPi3 and run indiserver, my Ekos client won't connect to the camera on the RPi3. I get the following message in the text box under the V4L2 CCD tab "Using default recorder (SER File Recorder)", and the light stays yellow.
Here is the command I use to start indiserver on the Pi:

indiserver -v -m indi_gphoto_ccd indi_lx200autostar indi_v4l2_ccd

Please help!

Do you have any link to those so I see what they look like?

Thanks for your quick reply! That doesn't sound too encouraging though, considering I have no programming skills whatsoever. Do you have any suggestion on how to trigger my D200 for long exposures in Ekos/Indi? Right now I'm limited to 30 seconds. I have a remote timer, which works fine, but then I cannot dither.

Hi everyone,
I'm new on this forum. I've recently bought this USB relay from Amazon ( www.amazon.it/gp/product/B00W3GRQNI/ref=...00_s00?ie=UTF8&psc=1 ). I intend to use it as a shutter release device for my Nikon D200. However, it has a HID interface, rather than a serial one, which is giving me a headache to configure. I'm running Kstar/Ekos under Xubuntu. This is what I get when I run lsusb:

maurizio@maurizio-AMILO-Li-1718:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 16c0:05df Van Ooijen Technische Informatica HID device except mice, keyboards, and joysticks
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
maurizio@maurizio-AMILO-Li-1718:~$

And this is what I get when I run dmesg:
[    3.996074] usb 2-1: new low-speed USB device number 2 using ohci-pci
[    4.180048] usb 2-1: device descriptor read/64, error -62

First, I am not able to any address for it in /dev. I have tried setting /dev/uhid, /dev/usb/hiddev0 and /dev/hidraw0 as shutter release ports in Indi, but no luck. I don't think this approach is going to work, as Indi should know how to send Hex ON/OFF commands.

Is there a way to use this device as a shutter release? If not, I will go on and buy a USB relay with a serial interface (I was considering buying this one: sigma-shop.com/product/7/usb-relay-contr...one-channel-box.html ). I should be able to see it as /dev/ttyUSBx, right?

Thanks for your help!

Maurizio
