I'm using blhost on Ubuntu16.04 and I have made sure that all dependencies required in the manual such as libudev.so.1, libc.so.6, etc are all installed and can be found on system path. But when I run
sudo blhost -p COM1 -- get-property 1
It reports an error
"Could not open serial port.Error: UartPeripheral() cannot open PC UART port(COM1), speed(57600 Hz)."
What's the problem here?
