Panel Views

The nRF Connect for VS Code extension pack provides several custom Views and terminal profiles in this area that are specific to the nRF Connect for VS Code extension pack, alongside the standard VS Code Views (such as Problems, Output, and Debug Console).

Panel Views section

The options in the Panel Toolbar change depending on which Panel View you have selected.

nRF Connect and nRF Terminal profiles

The extension comes with several custom options that are available from the Launch Profile... drop-down list (the arrow next to the plus sign icon) located in the Panel Toolbar area.

RTT and serial terminal options

The following custom options are available:

Action Description
nRF Connect Opens an nRF Connect terminal profile that is configured to work with west and the rest of the nRF Connect Toolchain and nRF Connect SDK environment. Alternatively, run the nRF Connect: Create Shell Terminal command from the Command Palette.
nRF RTT Terminal Establishes a connection to the board through RTT if it is supported on the selected device. Selecting this option frees a UART port that the serial port would use. However, you always need a SEGGER J-Link debugger connected for RTT to work.
nRF Serial Terminal Establishes a connection to the board through the serial port if it is supported on the selected device.

The RTT and serial connection options correspond to the options available from Connected Devices View. You can also start them from the Command Palette using nRF Terminal commands. Regardless of how you start them, the connections use the default configuration value presets.

If you lose your serial connection, for example when your device loses power, it will be automatically restored when the cause of the interruption is solved, as long as you do not close the connection window. This functionality is not available for the RTT terminal, which has to be reconnected manually.

Serial connection monitoring

Once connected, you can monitor the RTT or serial connection status from the Status Bar. You can start several connections at a time and move the connection windows to different parts of the UI.

nRF Connect terminal profile dependencies

The version of the nRF Connect SDK used depends on the value of the nrf-connect.toolchain.path setting at the time the terminal is created. Changes to this value are not picked up by existing terminal instances, so you need to create a new terminal to use the new environment.

All changes to the terminal environment are limited to this profile, so the default integrated terminal profile works as before.

nRF Debug

The nRF Debug View appears in the Panel View area when you start debugging an application.

nRF Debug View

The View is an integral part of the nRF Debug tool and provides dedicated Thread and Memory viewers.

Thread Viewer

The Thread Viewer shows information about specific threads in your application.
