Regarding App Connection: I've found that some networks don't allow the two devices (phone & PC) to connect (for example, CMU's WiFi). However, using a router with CMU's internet worked. Also, I've found that it's good to clean out the app from the background when connecting it to the Python script.
I've seen unexplained connection issues with the NeRFCapture App. (jc211/NeRFCapture#11)
We will try to release a better app and script to replace this for better support and to enable video streaming soon.
Hey, thanks for sharing.
What do you mean clean out the app from background?
Also, I'm using a home WiFi router, shouldn't be much of a problem but I'll test out the phone hotspot too
from splatam.
I'm referring to the closing of the app shown here: https://youtu.be/5K1KgMKWEH8?si=yG8PqRoS8tDpdZ-o&t=35
In our experience, I think home WiFi routers should also work. Not sure what's happening; maybe you could try cyclonedds ps
?
Re. phone hotspot: I needed to connect to an external phone's hotspot (apart from the active phone used for the app) to get things to work.

Oh the basic app closing, ok

The output shows no entities. Also tried to use an external phone to which the iphone and the pc connect to, but with no success.
Is there any configuration to do on the iphone or just open the app to the "online" tab?
from splatam.
That's interesting. You should at least see the Python script listed in the ps. Are you using the bash script to run the demo? Does it say waiting for frames ...
?
Yes, you just need to open the app to the "online" tab.
This is what I see when both the python script and the iPhone app are running and connected:

You'll find all i can see on this pastebin. Let me know if I can be of any help.
Edit: for the ps, I probably did it bad before, should've ran the ps check while the script was on. I did it now and still nothing appearing

I think what you are observing has to do with the interface. My system shows a wlo1
interface while the terminal output you shared shows wlan
. Maybe this could be the cause of the discrepancy?
The cyclonedds should discover the python script if it spawns correctly.

I don't think it can be an issue, that's only the name of the network interface i'm using to connect to the wifi, so I'm not really sure
The ifconfig command only shows eno2, lo(loopback) and wlan0
from splatam.
Another option could be to check the domain ID of cyclonedds: eclipse-cyclonedds/cyclonedds-python#194

If i got that correctly, both mine and your snippets both use id [0], I scanned that one while the demo was running but nothing. Where in the code do you choose the id to assign?
from splatam.
We don't explicitly set it. We use the default domain ID, which should be [0]. Not sure what's up.
I tried this demo on another system; the other system also has an interface of wlo1.

It's probably a nomenclature by the system, i'm running archlinux and he calls them wlan, maybe on ubuntu the name is different; all the same i don't think that's what causing the issue but let's see if others can confirm.

Hey, thx for sharing. I also have a strange issue.
When I tried nerfcapture using my ipad, it shows that my ipad connected to the host correctly with four entities.
Then I turned off my ipad’s wifi
And I tried it to using another iphone, but it cannot work with only two entities like the first img.
When I use the tablet again, I can still connect successfully.
I guess it's because the configuration has not been cleared completely but not for sure.
I wonder why it happened. Thanks again.
from splatam.
Have you ensured that the iPhone is connected to the same network?
That's definitely a weird behavior. Not sure what's happening internally with the NeRFCapture App's DDS.
We will have our own variant soon, which would be better and can also do video streaming.
from splatam.
For me, NeRF Capture
failed to establish a connection with my laptop while using my home WiFi. However, hotspotting from my laptop worked without any issues.
from splatam.
@Nik-V9 I've managed to make the cyclonedds service work on windows, but it chooses the wrong network interface (it chooses the ethernet connection and i want it to choose the wifi one). Do you know how can i do it?
from splatam.
Regarding my situation,iPad Pro can connect successfully, but my iPhone 13 Pro cannot.
The prerequisite is that your computer and iPad should be connected to the same network.
The steps are as follows: while in online mode, run "bash bash_scripts/online_demo.bash configs/iphone/online_demo.py" and wait for the message "waiting for frames..." to appear. Then, open NerfCapture on the iPad and wait for approximately 3 seconds until the app displays "1 Connection(s)" on the top right corner. Click "Send" and the computer will receive the corresponding data set.
from splatam.
I also have the same problem, the script bash bash_scripts/nerfcapture2dataset.bash configs/iphone/dataset.py always "Waiting for frames...". And I run cyclonedds ps print "Entities discovered: 2", but can not see the NeRFCapture APP. I am sure two device use same wifi, what can I do?
from splatam.
I have similar problem.

I found that my iPhone 13 Pro is the only device having dds connection issue, both my iPad Pro w/ LiDAR and iPad mini works.
I initially suspected that the dds on ios was choosing the cellular NIC over the wifi NIC but found that even if i put the phone into airplane mode the connection issue still existed.
Sticking to a iPad with LiDAR might be the solution to it currently.
