Hello @MichaelT
I. Are you using devcontainer on Ubuntu 22.04 inside some virtual machine? If so try to open new terminal and check internet connection in machine ping 8.8.8.8
II. The browser what you use is on your native system Windows or on Ubuntu 22.04 inside VM?
III. I think the easiest way to program Core2 with rosbot_ros2_firmware is to:
- clone or download repository on your native OS (Windows),
- open
rosbot_ros2_firmware
folder in VS Code, - download devcontainer extension,
- reopen folder in container,
- then run
pio run --target upload
Best Regards,
