I'm using TDoA3 but I'm unsure if the range data is being transmitted back or only the position data is being transmitted back

because in the crazyflie client the ranging data is a constant zero

Hi there,

I am wonder is it possible to read off the anchors distance to the crazyflie instead of the crazyflie position in python.

Or do i have to calculated it from the anchor position and the position that is read off the crazyflie?

hi i am wondering if there is any way or an example code that will allow me to reconnect a disconnected drone in python.

currently my python script would stall/hang if one of the drones is disconnected.

So I'm wondering if there is any failsafe code that would allow me to reconnect the drone

that solved my problem actually. I one of the anchors was addressed wrongly. But the error still seems a lot larger than in TWR mode. its abt +/- 20 cm in TDoA 3 vs abt +/- 5cm in TWR is there anyway to reduce this?

I'm using 6 anchors only. But I'm in a small room ranging abt 3x1.2x3m? Was wondering if it has anything with me setting the anchor positioning. But I don't really have anyway to check because the new cfclient update have the buttons greyed out.

I am having the same issue too. on both windows and ubuntu 18.04 LTS. Try getting an older version if you are using TWR and TDoA?

Have anyone tried to run the sample python codes with TDoA3? It seems like it is taking ages to get out of and when it does the position given by the estimate is stuck at pos: (-100.0, -100.0, -100.0). Have anyone had a successful flight with it yet?

I have the same issue too. But these are my thoughts and maybe you can try to recreate them not sure if it would help. 1) improper calibration of anchors and blind spots Not sure if there is any available scripts to calibrate the anchors automatically. I also notice the x and y position is some what...

Hi there, other then the craft must be facing in the x direction, must the nodes also be facing in the x directions? I have having some problems running the example code too. The position that I read off the the drone is accurate, but the drone still flies to one direction. I've edited the code such...

Not sure why when I tried to run the file ramp.py https://github.com/bitcraze/crazyflie-lib-python/blob/master/examples/ramp.py . The motors of my crazyflie do not spin. There is no error when I ran the code and it connects to my crazyflie. I am using ubuntu 18.04 Also is there a take off command fo...
