 ## Communicate with the DroidControlShip
-For the communication with the DroidControlShip a socket server needs to be enabled, which is disabled by default.
+The communication with the DroidControlShip goes via a Webots serial connection, which is disabled by default.
 
-Use the -s flag to enable it with default port 65432. Note, this will disable the standard logging, because the serial communication will automatically be routed over the socket. The SerialMuxProt protocol is used to exchange data in both directions.
+Use the -c flag to enable it with default channels (see _webots_robot_serial_rx_channel_ and _webots_robot_serial_tx_channel_ in [platformio.ini](./platformio.ini)). Note, this will disable the standard logging, because the serial communication uses the SerialMuxProt procotol for data interchange.
 ```bash
-$ program.exe -s
+$ program.exe -c
 ```
 
-The port can be changed via command line parameters, please use -? to get more details.
-```bash
-$ program.exe -?

-For simplicity a Platformio project task was added, which start the socket server as well.
