As I met several problems during test autonomous fly, I summarize them here.
1. Place UWB deck at the bottom of crazyflie, otherwise it affects tele radio. I was placing it at drone top. It frequently met connection problem, that radio cannot connect to drone in the client software.
2. Flash crazyflie firmware through radio failed
I followed the steps,
Code: Select all
cd crazyflie-firmware
make clean
make
make cload
So, I flash firmware through usb with drone in DFU mode, as https://wiki.bitcraze.io/projects:crazy ... opment:dfu said.python3 -m cfloader flash cf2.bin stm32-fw
Restart the Crazyflie you want to bootload in the next
10 seconds ...
Cannot connect the bootloader!
Makefile:380: recipe for target 'cload' failed
make: *** [cload] Error 255
3. launch lps-node failed due to radio permission I still can't find how to change radio permission. So I have to launch ros file in root mode.
4. cannot found drone position after launch "lps_node"
I launch lps_node by,
Code: Select all
roslaunch bitcraze_lps_estimator dwm_loc_ekf_hover.launch uri:=radio://0/80/250K x:=3 y:=2.3 z:=1.0
Thanks
