Re: Crazyradio connect issue.

Hi, Everything seems to work on the PC side: the behaviour you describe is correct and if nothing shows in the drop-down box it means that no Crazyflie was detected by the scan. So the problem seems to come from the Crazyflie not being detected. The most common problem is when the Crazyflie is setup...

Re: Using 2 Lighthouse decks with different configurations

Hi, This is technically possible but you are trying to do something for which the deck was not designed at all. The very fist step is indeed to change the identity of your other board, this can be done using one of the example python script: https://github.com/bitcraze/crazyflie-lib-python/blob/2c54...

Re: Flashing the Crazyflie in DFU update mode

Hi, As far as I know there has been no progress yet. The description I did in my previous message still stands: it should be a mater of a small modification in the firmware and a python script sending the right restart command to the Crazyflie. I created an issue on the firmware github project: http...

Re: Failed uart_syslink ASSERT

Hi, I cannot explain why you are getting this error then, this is something we will need to investigate. Loading the system at 100% is not advised though, I assume you are using the prio 0 as some kind of best-effort worker, which should work in theory but it is not very well tested. As for loosing ...

Re: LH Sample Frequency

Hi, As noted in the paper, we believe the large deviation is more due to inadequate post-processing rather that a property of the system. Overall though, LH1 has 2 base-stations strongly synchronized while LH2 uses synchronized base-station, this means that LH1 will always give more predictable meas...

Re: Failed uart_syslink ASSERT

Hi! These error are not common at all (this so rare that we where talking about removing the checksum from Syslink ...). My best guess as of what could be happening is that you are loading so much the system that it is missing bytes on the UART which causes the checksum error. There is no hardware f...

Re: Unable to Connect to Crazyflie

Thanks for the update and for the extra info! I looked quickly and the PIP libusb package is not libusb, it is a wrapper. Libusb is a C-implemented library. Though, the package called https://pypi.org/project/libusb-package/ seems to package the libusb lib. This is interesting and should be investig...

Re: Unable to Connect to Crazyflie

Hi, This is consistent with the behavior when libusb is not installed. Assuming you are using homebrew, you can install libusb with: brew install libusb When the client starts it will automatically scan for Crazyflie which will light-up the RED led on the Crazyradio. Edit: We have added help on Linu...
