pico_micro_ros_example is not running on Raspberri pi pico with micro-ros
I followed the guide in the link below to get "micro ros" to work on "raspberry pi pico".
https://ubuntu.com/blog/getting-start...
The environment I work in is a PC (Ubuntu 20.04, ros2 foxy), and the pico is connected via usb.
Finally, it seems to have worked, but communication via Ros2 foxy failed.
I entered the command as below.
ubuntu@ubuntu-System-Product-Name:~/micro_ros_ws/src/micro_ros_raspberrypi_pico_sdk/build$ sudo micro-ros-agent serial --dev /dev/ttyACM0 baudrate=115200
This resulted in the following
/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
