Using the Mbed Studio Serial Monitor view

By default, Mbed Studio automatically detects any board you connect to your computer and opens a Serial Monitor view, which displays the board's output. If you connect multiple boards, Mbed Studio opens a view for each board.

You can only have one Serial Monitor view open for each connected board. Close your board's Serial Monitor view in Mbed Studio before you open an external serial monitoring program.

To reopen the Serial Monitor view, select Serial Monitor from the View menu.

You can disable the automatic opening of the Serial Monitor view from the preferences. Go to File > Settings > Open Preferences and search for the Serial Monitor preference. Clear the Monitor Automatically Open checkbox if you don't want the Serial Monitor view to open automatically when you connect your board.
