camera toggle doesn't work about ardrone_autonomy

[ubuntuslave]

I can say that I faced the same problem with both of my AR Drones (v1.0 and
v2.0), so I stopped there. I heard it works for some other people, but
unfortunately not for me.

Hey!

I try to switch between the bottom and front cam with $ rosservice call
/ardrone/togglecam.
But the result is that the /ardrone/front video feed is passed to the
/ardrone/bottom so when i toggle i see the front video cam feed on
different topics and not different camera feeds on different topics.

I tired to launch the driver wity the ardroen.launch, my.launch and with
rosrun. Same result.
Am I missing something/ doing wrong, or this is a bug?

Is there any method to change the feed? I need the bottom feed for displacement tracking and image process.

That's interesting! Could you please tell me you Drone's firmware number?

One more thing. Does the camera toggle works when using iPhone app?

[ubuntuslave]

I remember it didn't work through the iPhone app either. I haven't flown the drone in a few months since then.

I previously my tutor tired with a smart phone(android OS) and the camera toggle worked, I'm using an AR-Drone 2.0 with Firmware: 2.2.6. Is this firmware outdated or toggle is not supported?

[zweistein]

Any updates on this camera issue?

I'm getting this issue with ROS Groovy. What ROS versions are you guys using?

[krisdestruction]

Also I am on the firmware 2.3.3. I'm considering upgrading to the 2.4.8 firmware.

[mani-monaj]

I will double check the camera toggle using the latest firmware (2.4.x). The older versions might have some problems with camera toggle.

[krisdestruction]

I restarted the whole system and restarted the drone. That seemed to fix the problem for me a few times.

Does anyone get this toggle to work? I'd be nice if both camera feed can be streamed at the same time without toggling

I am also having the same issue. I can toggle the cams easily with the iPhone app. However, the camera does not change using "rosservice call /ardrone/togglecam". I am using the latest version of the code and I do get the messages saying "Setting camera channel to : 1" or "Setting camera channel to : 0".
I also tried changing the parameter "video_channel" so as to change the default camera view to 1, however it does not have any effect either.
Any help in this regards will be greatly appreciated.

I will investigate the bug in camera toggle as soon as possible. Thank you for the report.

Streaming both cameras at the same time is not supported by the SDK though.

@NRS-ks The camera toggle works for me on ROS Hydro and AR-Drone 1 (firmware 1.1.15) with driver version 1.33. The Fuerte branch has been End-Of-Lifed. It is using an older version of the SDK. That might be the root cause of the issue. I strongly recommend that you consider upgrading to Hydro since Groovy is going to be EOL soon.

i'm working with python module. i set the bottom camera for setting, but it gives me the different images sometimes from front camera, other time from bottom camera. but i don't know what is wrong with it. i tried drone.setConfig("video:video_channel","1") but nothing happens. if anyone has solved this problem please let me know.
