Issue with flying multiple CF's with adding anchor 7 and 8

[anchekuri]

1. https://github.com/bitcraze/crazyflie-firmware.git This was the firmware I was using to flash the crazyflie.

2. I have made changes with the dwm_loc_ekf_multi_hover.launch and it was working without error but not accurately sometimes . like behaving crazy and not taking off or moving out of the field and hitting walls.

3. For crazyflie Ros I was using the latest master-branch version.

I have some doubts about anchor setup.

Right now I have 6 anchors from 0-5. As mentioned in the https://wiki.bitcraze.io/doc:lps:tdoa that I can use 8 anchors from 0-7. i added the 7th and 8th anchor to the anchor_pos.yaml. And when i run the command
roslaunch bitcraze_lps_estimator dwm_loc_ekf_multi_hover.launch uri0:=radio://0/30/250K/E7E7E7E701 uri1:=radio://0/30/250K/E7E7E7E702
then is was showing that there was error with anchor 6 and anchor 7 which are 7 and 8.

And also I have a question about dwm_loc_ekf_swarm_hover.launch. I has a code for 5 CF's can I use less than 5 or more than 5 for that or any restrictions are there to this launch file.

Thank you,
Appala Chekuri.

Hi, The question is more about the loco positioning and Crazyflie than about the Crazyflie ros driver. I copied the question and answered in the Bitcraze LPS forum: https://forum.bitcraze.io/viewtopic.php?f=16&t=2664&p=13415#p13415. I propose we continue the discussion there.
