error:[crazyflie_server-1] process has died [pid 20730, exit code -6

Hi,recently I'm trying crazyflie_ros.
I use the command
roslaunch crazyflie_demo hover_single.launch
and an error occurs:|
[crazyflie_server-1] process has died [pid 20730, exit code -6, cmd /home/liruocheng/catkin_ws/devel/lib/crazyflie_driver/crazyflie_server __name:=crazyflie_server __log:=/home/liruocheng/.ros/log/3e8cb1e8-53d2-11eb-96f0-f4939ff49e28/crazyflie_server-1.log].
log file: /home/liruocheng/.ros/log/3e8cb1e8-53d2-11eb-96f0-f4939ff49e28/crazyflie_server-1*.log
I restart the cf and the error still occurs...however, the problem was solved when I connected the cfclient once. But it will happen again when I restart the cf, so I have to connect the cfclient first before running the cf on ros...
I wonder why this kind of problems occurs. Right now I guess it may be the problem of the firmware. I have changed the firmware's makeflie and force the estimator as "kalman"
## These are set by the platform (see tools/make/platforms/*.mk), can be overwritten here
#ESTIMATOR ?= any
ESTIMATOR = kalman
CONTROLLER ?= Any # one of Any, PID, Mellinger, INDI
#CONTROLLER = Mellinger
POWER_DISTRIBUTION ?= stock
Then I do "make clean ---- make ------ make cload "
This problem will disappear when I use the official release 2020.09 -firmware-cf2-2020.09.zip.
Looking for your help,thanks a lot!!!!
