[Solved] Error when building rosbot_ros2_firmware

Hi @JanBrzyk

building the firmware works now - thanks.
But I am having trouble with uploading the firmware via STLink from the VSC terminal:

husarion@6e96541ebad4:~/rosbot_ros2_firmware$ pio run --target upload
Processing core2 (platform: ststm32@15.4.1; framework: mbed; board: core2)
------------------------------------------------------------------------------------------------------------------------------------------------------------------
Tool Manager: Installing platformio/tool-stm32duino @ ~1.0.1
Error: You are not connected to the Internet.
PlatformIO needs the Internet connection to download dependent packages or to work with PlatformIO Account.
husarion@6e96541ebad4:~/rosbot_ros2_firmware$ 

My browser works, has this something to do with docker or the devcontainer?
Did I miss some configuration (I am a complete newbie to Docker)?

After restarting my VM and running VSC again in devcontainer I get the message that PlatformIO cannot be activated because C/C++ extension has to be reloaded, but reloading results in the PlatformIO activation error message and so on …
