Re: crazyflie schematic...

This seems to be a KiCad 5.x issue. Apparently with KiCad 6 the PDF generated will be searchable. We plan to convert all our projects to KiCad 6 once it is released, we will then be able to generate searchable schematic. In the mean-time, I generated one for the Crazyflie 2.1 using the nightly versi...

Re: No tf data. Actual error: Fixed Frame [crazyflie/base_link] does not exist

Hi, What do you mean by prototype Crazyflie? How modified is it and have you verified using the Crazyflie client that everything was working? As for ROS, I have not used it for a while, but I would advise you to look at Crazywarm instead: https://crazyswarm.readthedocs.io/en/latest/. It is ROS based...

Re: Crazyradio not working

Hi, It does seem that the data line pad has been pulled when the connector bent. This behavior is consistent with USB data line not connected. One thing you can try is to bend the connector back and try to re-solder a bit the data line, with a bit of luck this will reconnect the data line and make t...

Re: Is there a simple way to just re-install all firmware on crazyflie?

Hi, You should only need the bootloader and then you can flash everything over the radio. Dfu flashing is considered a recovery mode for the Crazyflie (exactly your use-case here :-), so it is used to get the radio bootloader back in place and then use the radio bootloader. There is ways to flash th...

Re: emergency landing - using NRF IO pin

Hi, If I understand you plan well, what you want to do is: - Send a standalone radio packet to the Crazyflie (outside of the current link connection) that tells the Crazyflie to land - Set the nrf_io_1 pin in the packer handler when this packet is received - Connect the nrf_io_1 physically to an STM...

Re: AI-deck and P2P

Hi, This is an interesting project and it sounds good that you got something working with your laptop first, it means that most is already done and it should be easier to go P2P. P2P with the ai-deck wifi connection is possible but you would have to implement most of it by yourself both on the ESP32...

Re: CPU usage when logging from Raspberry Pi

Hi Jesse, It unfortunately sounds correct. The main problem is that the radio USB communication happens at pretty low level: the python lib has to send and receive every single packets and since the Crazyflie downlink is implemented using ack packets, the lib has to send packet very often to impleme...

Re: Crazyflie Camera

Hi Barry, Kimberly flew the Crazyflie with the esp eye on Friday and it does work! The only issue is that the board consumes a lot of energy and so it requires a good well charged battery to be useful at all (we are not sure where the big power draw come from, wifi or camera ...). The final setup lo...

Re: Crazyflie Camera

I am not going to have a straight answer but just a couple of ideas. There is the ai-deck that we have in early access but it would be grossly overkill for this use-case and so quite expensive. Otherwise we actually have an esp-eye lying around at the office and we just attached it to a Crazyflie. W...

Re: Crazyflie fails after connecting 3 boards

Hi, It seems that something is failing during Crazyflie startup. What expansion boards where connected? I is unlikely this has caused a big problem unless the decks where very incompatible. One way to debug the situation is to connect the Crazyflie over USB and connect to it with the client. The con...
