Re: Radio Not Connecting

If both red and green LED lit up upon connection and you see the Crazyradio in the list of VirtualBox device and manage to click it to enable it in virtualbox, then it is very likely that the radio firmware is going well. What you are seeing in the console indicates that the client does not see the ...

Re: Flying Crazyflie to a specific position setpoint

Hi, For your first question, yes you should call commanderSetSetpoint() at regular interval. You can see an example of that in the multiranger push demo: https://github.com/ataffanel/crazyflie-push-demo/blob/8b9b2e8/src/push.c#L105-L106. You need to fill up the setpoint structure to set X,Y,Z as abs...

Re: Multiranger

Hi, The Crazyflie has no collision avoidance algorithms so you will have to implement this part. One way to go is to send high-level-commander goto set-points using the function cf.high_level_commander.go_to() (you can see it used in this example: https://github.com/bitcraze/crazyflie-lib-python/blo...

Re: GUI doesn't display absolutely on ubuntu

You GUI looks correct to me, what function are you missing?

If you are talking about the missing tabs, you can enable them with the menu "view->tabs".

Re: Timer configuration (Interrupt service routine)

Do you actually need a hardware timer? If not, you can run something at 1 KHz in two ways using the RTOS: 1. Setup a FreeRTOS timer at 1KHz. Timers are running at quite low priority and you are not allowed to keep your function running for long (same as with an interrupt ...), so you might get some ...

Re: Radio Not Connecting

Hi! It seems that there is two problems: the connection instability and the dongle not recognized anymore. The first thing to check is that you are running the right firmware. You sais that the dongle briefly flashes RED when connected. Are you sure that it is only red or is it both red and green? I...

Re: LPS with ROS

Hi, you do not need LPS support in ROS since with LPS you get the position in the Crazyflie: as soon as LPS is setup, you can send position setpoint and get position estimate from the Crazyflie without needing special support on the client side. This is in contrast to motion capture systems that do ...

Re: Control of two Crazyflies

It sounds like the possibility 1 is the best for your then. The only change to make to be able to launch 2 cfzmq client is to change the ports used by the ZMQ sockets . I pushed a change to cfzmq that adds a parameter to change the base-port: https://github.com/bitcraze/crazyflie-clients-python/issu...

Re: Frequent fly aways, toiletbowling and flips with Lighthouse positioning

You might be hitting #531. We are investigating the problem right now. If you use a commit before the static memory change (for example 6ba33b7ce9), you should not see the problem.
