PS C:\Users\olausr99\Documents\PlatformIO\Projects\TLMControl> pio device monitor --port --baud 115200
Usage: pio device monitor [OPTIONS]

Error: Got unexpected extra argument (115200)
PS C:\Users\olausr99\Documents\PlatformIO\Projects\TLMControl>

The problem seems to be that no COM port is passed on the command line

EDIT: My bad!! Its too early in the morning and it seems i didn’t sleep well. I forget to choose (I don’t know why is blank now) the com port

Sry!
