Turning off/on the camera

[xiaoshan-lin]

Hello,

We use the opencv-viewer.py to get the image from aideck. Wondering if there is any way we can send commands to the aideck to turn off and turn on the camera? Thanks in advance for your help and support.

Do you intend to send these commands from the pc?

In that case you can use the app channel to send data (in this case a camera command) to a Crazyflie app using a Crazyradio. For the communication from the app to the AI-deck check out the STM-GAP8 CPX communication example. Based on the incoming data you can use pi_camera_control on the GAP8 side to start/stop the camera.

Yes, we want to send the commands from the PC. We found a Python example in examples/app_appchannel_test/ .

Is the appchannel supported in the cpp Crazyflie Class, or it is only available in Python cflib?

Hi! The link that you shared is actually the c-based app implementation for onboard of the Crazyflie. The python class for the app channel is in the cflib here: https://github.com/bitcraze/crazyflie-lib-python/blob/master/cflib/crazyflie/appchannel.py

Just mind that if you have any questions about the ecosystem, it is best to start a discussion in https://discussions.bitcraze.io/, since that is the main place for support. We use issues to indicate pieces of 'work' and changes necessary to the firmware/software
