2. In DevEco Device Tool, choose REMOTE DEVELOPMENT > Local PC to check the connection status between the remote computer (Ubuntu development environment) and the local computer (Windows development environment).

   • If is displayed on the right of Local PC, the remote computer is connected to the local computer. In this case, no further action is required.
   • If is displayed, click the connect icon.

   

   NOTE This operation is required only in remote access mode (in the Windows+Ubuntu hybrid development environment). If the local access mode (Windows or Ubuntu development environment) is used, skip this step.
