it is possible to specify upload-port from the CLI, but not monitor-port (feature request)

[hamishcunningham]

If working with multiple boards connected at one time (e.g. when developing a test rig), there are multiple upload ports and multiple corresponding monitor ports. At present it seems impossible to specify the latter.

For example
pio run -e unphone7 --upload-port /dev/ttyUSB1 -t upload -t monitor
will correctly upload to ttyUSB1, but will then monitor on e.g. ttyUSB0

Adding a monitor_port to the .ini file can solve this, but then doesn't cope with subsequent changes.

Addition of a --monitor-port option would solve this, as would defaulting monitor-port to upload-port instead of trying to guess it when the latter is present. An alternative would be to allow overriding of .ini settings from the command line.

Thanks!

Do you type this command manually?

[hamishcunningham]

Yes, or script it, depending on what I'm working on.

Please re-test with pio upgrade --dev. Thanks.

[hamishcunningham]

Brilliant, works perfectly :)
Thanks!
