cfclient: python error "KeyError: 'bcLighthouse4" with grayed out Command Based Control !

[hyperonex]

Dear All,
After installing the cfclient. I've been successfully connected to the Crazyflie however the Command Based Control was grayed out where all the buttons were disabled (non clickable).
While checking the logged messages to the screen I saw the following python error:

===== 2023.12.06 10:12:37 ===== INFO:cflib.crazyflie:Callback->Connection completed [radio://0/80/2M] Traceback (most recent call last): File "/Users/achraf/Library/Python/3.9/lib/python/site-packages/cfclient/ui/tabs/lighthouse_tab.py", line 391, in _connected if self._helper.cf.param.get_value('deck.bcLighthouse4') == '1': File "/Users/achraf/Library/Python/3.9/lib/python/site-packages/cflib/crazyflie/param.py", line 381, in get_value return self.values[group][name] KeyError: 'bcLighthouse4'
This error was reproduced in macOS Ventura and Windows 10 as well with the same cfclient gui behavior in both OS.
The console was displaying that the crazyflie is ready to fly!

Please note that I didn't connect any input control device.

Any help on that please?
Regards.

Hi! So I missed it in your support question but did the Crazyflie had a lighthouse deck connected? The command based flight is only active if there is an positioning system attached.

ah yeah that would be interesting to see. I do think we implemented some kind of param fix that might have an influence which requires both the cflib and the firmware to be updated. Would be good to check out.

Unfortunately the command based flight is still disabled after loading the last firmware and unmounting the multiranger on macOS ventura, Windows 10 and Ubuntu 22.04.

This is the shell output:

And this is the cfclient output:

There is no flowdeck recognized on your crazyflie so that indicates a different issue. Did you try removing the multiranger and trying again? The console input needs to say that it is recognizing the flow deck.

Thank you very much. Yes indeed the decks was not well mounted!
After upgrading to the last firmware and remounting the decks everything is working well.
