Re: Lighhouse FPGA not booted
The lighthouse bin is flashed to deck using the python client. It is a bit tricky to flash only the lighthouse deck and the easiest solution is to 1. Install the deck on your Crazyflie 2. Start the python client, connect to the Crazyflie 3. Open the bootloader dialog from the "Connect" men...

Re: Failed to change Crazyflie address through Cfclient
It all sounds a bit strange, I have not seen this.
Did the reset of the EEPROM solve the problem, is the "Write" button enabled now?

Re: Trajectory creation
Hi! The example you are looking at is unfortunately a bit tricky to use (I wrote it a long time ago). A better way to go is to use the high level commander in the Crazyflie. It works by uploading a trajectory to the Crazyflie and then tell it to fly this path. There are two trajectory formats, the c...

Re: Cannot fly more than three vehicles using an external positioning system.
I think your list of potential problems is pretty good. You could possibly also check if there is any noise in the position you get from the mocap system (OptiTrack). This us usually not a problem but better to be safe than sorry :-) If the signal is a bit noisy you can increase the standard deviati...

Re: Recovering Bricked CFs
Hi! The good news is that it is not (should not be) possible to brick a CF by normal usage or flashing, which means that it should be possible to solve :-) First of all, Crazyflies can unfortunately not be flashed via USB, you need a Crazyradio. The procedure from the client is: 1. Turn off the Craz...

Re: Many crazyfies and two radios
Hi! Changing channel takes some time for the radio so the best setup is to use one channel per radio dongle and different addresses for the Crazyflies. Do not use the same channel on both radios as it leads to packet loss. For instance do something like this: Radio 1: radio://0/50/2M/E7E7E7E701 radi...

Re: Modifying the Kalman Filter?
Hi Jiawei! 1. The Kalman filter is reset by the kalman supervisor https://github.com/bitcraze/crazyflie-firmware/blob/2022.03/src/modules/src/kalman_supervisor.c. It resets the kalman filter when the position or velocity is "unreasonable". You can modify it (or disable it) according to you...

Re: Cannot fly more than three vehicles using an external positioning system.
The frequency of transmission is 0.5 Hz cycles. This sounds a bit low to send mocap position to the Crazyflies at 0.5 Hz, you could try to increase it to around 5 Hz to see if it works better. The CF can manage to fly for a while using only internal sensors, but 2 seconds is quite long, the risk is...

Re: Avoiding the compound statement "with" for the crazyflie
The Swarm class is probably not the best solution for you, even if it probably is possible to do it :-) The key is to understand what "with" is doing, it is called a "context manager" in python, see https://docs.python.org/3/library/stdtypes.html#typecontextmanager). The "wi...

Re: Avoiding the compound statement "with" for the crazyflie
Check out the Swarm class (https://github.com/bitcraze/crazyflie-l ... e/swarm.py)
There are some examples here https://github.com/bitcraze/crazyflie-l ... ples/swarm
