Re: Error while updating firmware

I could verify that you are hitting a newly introduced bug, the workaround is either to remove the flow deck before programming or just restart the client (the Crazyflie is left fully programmed in firmware mode). I created tickets in the Crazyflie client and Crazyflie python lib repos to track the ...

Re: Autonomous flight using wall following

One good example you could get started with is the multiranger push example: https://github.com/bitcraze/crazyflie-lib-python/blob/336815a404caac7ccf7638b083bee7351eae19ec/examples/multiranger_push.py. This example runs in an infinite loop and so it will allow you to hover until the battery is empty...

Re: Connection problems with radio and delay

You need to look at the Crazyradio leds, not the Crazyflie one. On the Crazyflie side green means one packet was received and red means one packet was sent. It is normal that it is mostly green when using the android client over bluetooth since the android client is only sending commander packet, it...

Re: Using the Lighthouse deck for visible light communication (VLC)

I do not thing you can extract signal strength from the TS4231. Once the TS4231 is setup, it acts as a signal detector and gives us only two 1bit information: envelope and data (ie. data is outputting the carrier). As far as a know it is designed for this use-case only. The FPGA is currently program...

Re: Connection problems with radio and delay

Is the radio RED led lighting up a lot? While communicating with the Crazyflie, the radio green led is lit when a packet is sent successfully and the red led when the packet was lost. So looking at the led can give a good idea of the radio link quality. One thing I have seen is that the radio qualit...

Re: Crazyradio PA No Wireless Connection

This likely means that your Crazyflie is not setup with the default address. The way to solve that is to: - Connect to the Crazyflie using USB connection with the graphical client - When the connection is open, "connect/configure 2.x" will be active - Change the address back to 0xE7E7E7E7E7 (or take...

Re: Crazyradio PA No Wireless Connection

Hi, Thanks for the detailed report of what you have tried. Channel 0 datarate 2M (so radio://0/2M) is the configuration of the bootloader, it is the channel that will be configured by the Crazyflie when putting it in bootloader mode. So if you always start from your step 1), what you are observing i...

Re: CrazyradioPA isn’t recognised on Mac or PC.

The error message you took a screenshot of is emitted by linuxjsreader.py which is the gamepad driver used in the client, it does comes from the gamepad. Though, the error is about the device being disconnected so since both the gamepad and the radio are connected over USB, there might be a link. On...
