The following command installs a previously uploaded SUIT envelope file on the device connected to the serial port COM7 on Windows (run nrfutil device list to check the serial port name for your OS):
nrfutil suit install --serial-port COM7
This command installs the file and produces no additional output.
You can also combine uploading and installing. For example:
nrfutil suit upload-envelope --envelope-file root.suit --install --serial-port COM7
