Problem with Sony RX100 M4

[mar20kus]

Hello falk0069,

I've a problem getting the full connection to the camera.

Camera Side
If I do "Send to computer" the camera says

Connecting...
linux
SSID:foo.bar

looks good till now, but that's all.
After some minutes the camera says, that it can't get a connection to the computer.

Computer Side
NOTES:

• I've changed the python script a little bit.
• The code never comes to the lines

Even if I run photo2 with the IP-address found by sony-pm-alt.py gphoto2 can't continue.
For me it looks like the communication is only from the camera to the computer but not back.
Interesting - I don't know if it's important: I can configure a network settings with
IP-Address
Network Mask
Gateway
and I use 192.168.1.XXX
but the camera always uses a different 169.254.XXX.XXX address.

My gphoto2:

This version of gphoto2 is using the following software versions and options:
gphoto2         2.5.3          gcc, popt(m), exif, cdk, aa, jpeg, readline
libgphoto2      2.5.3.1        all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.10.0         gcc, ltdl, no USB, serial without locking

Any ideas?

That 169.254 address is an automatic private IP address. An IP in this range means that the camera cannot see the network. Do you disable DHCP on your wifi router? Your camera need to be able to find an DHCP server (typically running on your router) in order to get a 192.168.1.x IP address. That is the only way your camera and your computer will be able to communicate. You might also want to check if there is a way to set a static IP address (192.168.1.xxx) on your camera. This is the first I've heard of someone having the 169.254 issue on their camera.

Thank you for your reply. I double-checked again. "DHCP" is turned OFF on my WiFi-Router.
As I wrote above the Sony RX100 has a feature "AccessPoint Settings" - "IP-Address Setting" - "Manual"
There I define my 192.168.1.x IP-Address, 255.255.255.0 Netmask and the 192.168.1.x Gateway. But these settings are simply ignored. As I see in the DebugOutput of the script, the camera answers with an 169.254.x.y address.

The wifi-router is 192.168.1.1
The Gateway is 192.168.1.121

My "normal" routing table on the computer I want to use as target for the camera:

Kernel IP routing table
Destination     Gateway       Genmask         Flags Metric Ref Use Iface
0.0.0.0         192.168.1.121 0.0.0.0         UG    0      0     0 wlan0
192.168.1.0     0.0.0.0       255.255.255.0   U     9      0     0 wlan0

When I want to access the camera I add the 169.254.0.0 net so the routing table looks like:

Kernel IP routing table
Destination     Gateway       Genmask         Flags Metric Ref Use Iface
0.0.0.0         192.168.1.121 0.0.0.0         UG    0      0     0 wlan0
169.254.0.0     192.168.1.1   255.255.0.0     UG    0      0     0 wlan0
192.168.1.0     0.0.0.0       255.255.255.0   U     9      0     0 wlan0

Perhaps the routing table is not quite correct ...

If your camera doesn't have a 192.168 address, I don't think it will be able to communicate with your PC. My understanding is these IP ranges are in the private range and aren't routable. I'm sure there is a way but probably involves SNAT/NAT and/or iptable trickery.

Why are you against using DHCP on your network? You can still statically assign your IP addresses, but at least then your camera will get a valid IP on the same network. I really think you need to figure out a way to get your camera to have a 192.168.1.x address in order for things to work.

Status:

The key-point was your statement [...]
Your camera need to be able to find an DHCP server (typically running on your router) in order to get a 192.168.1.x IP address
...

So I enabled DHCP on my WLAN-Router.

After this and ... some quirks ... I managed to send a file from the camera to a computer.
I usually don't use DHCP in my network and had problems with some of my raspberry-pis: they took DHCP-addresses.
Ok - I'm not very firm with DHCP (I told my WLAN router to accept only the MAC-Address of the Sony Camera - but it seems that this didn't work).

My experience:
Transfer from camera to computer worked:

gphoto2         2.5.11         gcc, popt(m), exif, cdk, aa, jpeg, readline
libgphoto2      2.5.12         all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.12.0         gcc, ltdl, USB, serial without locking

Transfer from camera to computer did not work:

gphoto2         2.5.3          gcc, popt(m), exif, cdk, aa, jpeg, readline
libgphoto2      2.5.3.1        all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.10.0         gcc, ltdl, no USB, serial without locking

Thanks for your support and your script.
