Hey everyone,
Im a choreographer/dancer so I’m not super familiar with all the technical stuff in detail.
I still want to build a Prototyp drone to use it with the lighthouse system (and dancers)
I have a drone now and I was able to flash the software on it but when I start it I get sounds that don’t sound like „hey I’m ready to go“.

I was wondering if there is a table of buzz codes or something that can tell me what these sounds mean.

About the sound: it’s making 5 sounds. 3 raising then a low and then a high sound.

I hope you can help me.

Wish you a wonderful day.

The Crazyflie does a beep for each motor at startup. Sort of a way to audible hear that the drive system is OK and you should also see each propellers spin. I think you are hearing 4 sounds which is just how it should be.

Hey,
the propeller are not really spinning but is see a tiny micro movement.
I thought maybe these sounds can give me a hint of where the mistake is. Cause I do not hear 4 but 5 sounds.
3 fast raising sounds and then two more.

my guess would be that maybe some cable have been put together the wrong way.

i have a picture and a short video in my dropbox what might help to see what going on here.

I hope you can help my find the mistake.

Happy easter days

Thanks for the video, that clarifies it a lot. Did not think you had a Bolt at first, should have read the title better

The ESC sound is as it should. The first three sounds are the startup sound and the two last are that they are receiving a signal. I would advice you to try the setup without propellers first. If you know how to build the firmware I would also advise you to select the OneShot125 ESC protocol as it will result in a better flight.
Then select "Motor configuration" -> "ESC protocol" -> OneShot125
Build and flash firmware.
