DDserver on RaspberryPi can't get list of Camera connected

Hi,
I've installed the DDserver in a RaspberryPi. The DDserver is running and I plugged the Canon 600D via USB, the Rpi detects it

But when I try to find/connect it in the app, I got error:

Do you guys know where can be the problem?

Is your Raspberry PI at address 192.168.0.20 ?
Try starting ddserver as root (sudo ./ddserver)
Check that the system didn't mount the connected camera SD card.

I had this problem. Make sure:

- Your DSLRDashboard client device and DDServer machine are connected to the same network.
- You are running DDServer as root.
- You turn the camera on *after* DDServer is running.

I'm successfully running this on the RPi Zero W. I do recommend compiling it -O3. That does improve the live view framerate just a bit (it can use everyhing it can get ;-)

@Jarrod How do you connect your DSLR to the RPI Zero W? I purchased this https://www.modmypi.com/raspberry-pi/ra ... sb-pi-zero
but I noticed some slowdown in image transfer but not sure if the adapter is the problem.

Currently I use micro USB male to USB A female (connected to Pi Zero), inline with mini-USB male to USB A male (connected to Canon 60D).

Ultimately I'd like to get rid of the USB A connection altogether so I have this on order:

As for image transfer speed, I'm a brand new user so I don't have the experience to say whether that aspect is working as expected or not. But for single frame capture I successfully got JPG and even CR2 to transfer over the wifi and was not put off by the speed.

I did some more test and the image transfer works as it should when I connect to the RPI Zero wireless AP.
The image transfer is only slow when I use the network port that is available on that USB hub. So I guess the problem is with the USB hub.
So the RPI Zero W is a very nice replacement for the MR3040/MR3020.
Using with something like this: https://www.modmypi.com/raspberry-pi/po ... ero%20lipo
you can also add power to it with a LIPO battery.

How did you setup the AP on the Pi Zero W? I tried last night and successfully put the Wifi in AP mode but never got qDD on my iPad or laptop to detect the server instance...

For Raspbian jessie I followed the official instructions: https://www.raspberrypi.org/documentati ... s-point.md
For Raspbian stretch that didn't work but I found alternative instructions here: https://www.raspberrypi.org/forums/view ... 3#p1204633
expect the iptables roules.

I needed to manually add the AP to my Android device but after that it is displayed and I can connect to it.

Thanks, I will give those a try tonight.

Good link for the lipo piggyback. One issue I discovered with that one is there is no charging circuit. I found two other options that include a charging circuit. The first one comes with a battery, but without hacking the hw itself you are still powering the Pi over USB so maybe it's not really better than using a normal lipo cellphone charger pack. It's also the Pi3 form factor, so not ideal for space-savings. I actually have one of these to use with my Pi3, where space savings is not really an issue but I just want to not be tethered to the wall:

I also found this one which looks promising for use with the Zero:

Or if you care about price more than looks/form factor just duct tape one of these to your Pi ;-) :
https://www.amazon.com/External-Battery ... ttery+pack

I have one similar to this and it's a good compromise because it's small and has the built-in cable. I might just velcro it to my Pi Zero W case :-)

Hi guys,
Thanks for the suggestions. However it's still not working.

Image

Yes, the IP for the Rpi is 192.168.0.20
Yes, the Rpi and my phone are in the same network
I'm running DDserver as root

Image

Image

I'm turning on the Camera after checking that DDServer is running.

Image

Maybe there's any other order to "turn on" the things? or plugging the camera..? :(
