Re: How to control more than 50 crazyflies?

Hey Arnaud and Nickson,

Is it possible the Crazyflie crashes because of the watchdog timer?
As in: one of the drones is not receiving packets for 5 seconds because the radio queue is full with messages because it can only procces so many at a time.

Just wondering,
Kind regards,

Jasper

Re: Lighthouse positioning is not reporting any location

Yeah, so after close inspection it looks like the yellow led also comes on for the tiniest amount of time, then all the leds stay off.
So it would appear my firmware image is malfunctioning. Is that the lighthouse.bin file?
Is there a way i can rebuild that?

Thanks for your replies!

Re: Lighthouse positioning is not reporting any location

Hi Tobias,

Thanks for your quick response.
I have 2 Lighthouse decks: on one of the decks the lights both turn off, on the other both stay lit... (Its the decks, ive cross-checked with the drones)
What does each led say?

Also, the angle logs stay at 0.

Thanks in advance!

Re: Communication between 2 crazyflies and message passing

Easiest way i can think off is to use the PA dongle and let both drones communicate via your basestation/computer. Set up a log variable on drone A to monitor the battery level, aswell as its position. When the battery level reaches a certain threshhold give a command to drone B to fly to the last k...

Re: Keeping the quadcopters stand still in the air

Hey mnguyen, the 2 cm variation is normal (atleast its also present with other drones). This is due to up to 10 cm accurate distance readings from the sensors. As for the degraded performance with multiple drones: Are you using TWR (two way ranging?) or TDoA (Time difference of arrival)?. If you are...
