I have fixed that in the past, it's probably some deadlock. Can you reproduce it with the Swift Example? Or the Python or C++ code? If yes, I'll be quicker in debugging it.

Yes, I can reproduce in the Swift Example app (https://github.com/mavlink/MAVSDK-Swift-Example) using the latest master of the Swift SDK. You just need to add the two pieces of code I posted above. First connect to drone via wifi, then subscribe to camera Status, and last try to set some camera setting and you should see the issue.

@douglaswsilva I wrote some instructions that might help you speed the process along.

Thank you @unipheas, that's actually a really nice tutorial!

@julianoes Thanks for the example. I will try to build and test it with our internal camera version.
One of our engineers reported a bug in the MAVSDK, but I have to verify this first. I'll keep you posted.

I reproduced the issue with the test app you provided. Thanks!
It happens without ST10C - direct WiFi connection is enough. I haven't been able to verify the bug reported by one of our engineers, though.
I will escalate the issue to the camera team. They should be able to give me a clear answer why we have this lockout in our internal camera version and not in the public one.

@douglaswsilva is this a continuation of #136 and #137?
from mavsdk-swift.
douglaswsilva
commented on September 7, 2024
It is triggered by #136 but in this case, it is cameraStatus subscription that actually causes the issue of locking communication with the drone.
I believe #137 is an unrelated issue.

@julianoes Dario and Alessandro asked if you could take a look at this and let them know if there's anything they can do on their side.

@julianoes Do you want me to try to reproduce it in python. I don't have the python build system installed, but can give it a shot. It will just take a while to get everything set up.

@douglaswsilva if it's reproducible in the Swift example that's fine. I'll try that next week.
Edit: I put it on my todo list, hopefully it doesn't fall off again.

I pushed some fixes that we can try: mavlink/MAVSDK#796
I haven't been able to test them yet or reproduce the issue though.

FYI: I'll merge the PR as soon as the CI passes, and I'll make a new release of MAVSDK for you guys to test.

Hi guys,
I just tested the new mavsdk_server that @byuarus built from mavlink/MAVSDK#796 and unfortunately we are still getting the same issue. I tested using the DronecodeSDK_Swift_Example app connected to the camera via wifi (same thing as I posted above). I subscribe to cameraStatus and then try to setSetting after, this is the output (I was printing the callback from camera status, so it was printing values until I call setSetting):
Camera Status: CameraStatus(videoOn: false, photoIntervalOn: false, usedStorageMib: 15342.5, availableStorageMib: 15082.0, totalStorageMib: 30424.5, recordingTimeS: 0.0, mediaFolderName: "727E90HD", storageStatus: Dronecode_SDK_Swift.Camera.CameraStatus.StorageStatus.formatted)

I tried to reproduce this with the Example with some hacks but it worked fine.
This was using the iOS simulator and connected directly to the camera Wifi.
@douglaswsilva
Does it happen for you over Wifi directly or just through the ST10C?
And if so could you change my branch so that all I have to do is to press a button to reproduce it?
Thanks.

@darioxz if you have a link to a pre-release camera update to test against, just let me know.

They should be able to give me a clear answer why we have this lockout in our internal camera version and not in the public one.
It could still be a bug in MAVSDK as well (since it should not lockup either) so if you wanted to provide a pre-release to me directly for debugging that would be good.
