Monitoring
Watch your device's serial output with rake monitor.
Open a serial terminal connected to your device:
$ rake monitor
This calls esp-idf-monitor directly (falling back to the idf-monitor
executable if the esp_idf_monitor Python module isn’t importable), reading
the baud rate and ELF path for symbolicated backtraces from
build/project_description.json — so, like rake flash, it always matches
your last build.
Choosing a port
Just like flashing, set PORT if auto-detection picks the wrong device:
$ PORT=/dev/tty.usbserial-0001 rake monitor
Next steps
Once your device is flashed and you can see its output, head to Advanced
Usage to enable WiFi, tune memory, or run under QEMU — or back to
Quick Start for a refresher on using picoruby-shell
itself.
