How to connect using serial port

To connect to a device using a serial connection:

1. Connect the device to the same machine you are using to run the extension.
   The device appears as an entry in the Connected Device View.

   Important

   SEGGER J-Link compatibility is required for devices to show up in the Connected Devices View.

   • If you are working on Windows and your device does not show up in the View, but it does have the J-Link OB on-board debug probe, check if you have SEGGER USB Driver for J-Link installed (required for support of older Nordic Semiconductor devices in nRF Util, as per extension prerequisites).
   • Some devices, such as the BBC micro:bit, do not have J-Link by default. You can convert the onboard debug interface to a J-Link OB using the J-Link upgrade instructions.

2. Expand the device entry.

3. Click the Connect to Serial Port button to the right of the serial port entry to start a serial connection.

   

   The extension prompts you for configuration settings for the given connection type.

4. Select one of the following options for the connection from the Command Palette:

   • Default 115200 8n1 preset configuration values
   • Custom Other configuration values

   Note

   Only customize the connection values if you have changed the default UART driver settings, to make sure both sets of values are matching.

5. Optionally, if you chose Other in the previous step, select the custom baud rate, data bits, and stop bits for the connection.

After the connection is established, a new terminal entry is added in the Panel View, with its name corresponding to the name of your device if you renamed the device.
