GoPro Hero9 control via USB issue

[cristianilea-lateral]

I'm trying to control the webcam via USB (I got it to work via Wifi). I tried a lot of things and I can't seem to get it to work via USB. I should note that I've downgraded my firmware to v1.22.

Here is the ip of my Hero9:

I'm also aware of these tickets, and they did help to some extent (because I was doing some things wrong): #168 and #151.

Here is my code:

from goprocam import GoProCamera
from goprocam import constants

gopro = GoProCamera.GoPro(ip_address="172.27.180.54")
gopro.take_photo()

Here is my output of my code:

Waking up...
Waking up...
Waking up...
/bin/sh: vlc: command not found
Waking up...
Error, camera not defined.

Then I get an exception at the line gopro.take_photo():

Exception has occurred: TypeError
argument of type 'NoneType' is not iterable

What should I try next?

Hi, what version of gopro-py-api are you using?

[cristianilea-lateral]

4.1.0 installed with pip

Python is not my main programming language, so bear with me :D.

I went step by step with the pycharm debugger and it seems that it gets stuck somewhere in whichCam. This line throws an exception and then it goes downhill: response_raw = self._request("gp/gpControl")

It builds the following uri 'http://172.27.180.54/gp/gpControl'. If I try to make the request manually I get an exception like urllib.error.URLError: <urlopen error [Errno 61] Connection refused>

Then it's not the correct IP... Have you tried with 172.27.180.51?

It's very important you look at the examples, look how I did it, you pass an interface name to getWebcamIP as well as setting webcam_device to the interface name. Then it should work.

With 172.27.180.51 it works... but why?

[KonradIT]

Because the GoPro listens on the 51 octet of the IP.
