The following procedure shows how to prepare a device for remote connections and connect to it within LAN. The device is connected to the remote server using USB.

Complete the following steps:

  1. On the machine where the J-Link debugger is physically connected, open SEGGER J-Link Remote Server.
    Use the latest version tested and recommended by Nordic Semiconductor, as per prerequisites.
  2. Configure the J-Link remote server to match your network configuration.
    For example, the following configuration example uses USB as the J-Link connection and provides the serial number of the remote device; the server is configured to use LAN and uses the default listening port.

  3. Copy the listening port number. This is your PORT.

  4. Click OK.
    The remote server starts and waits for client connection.

  5. Copy the client connection IP string. This is your HOST.

You can now use the --remote-jlink option with the HOST and PORT values configured for the connection. In the case above, this is 192.168.1.55:19020.
