The main microcontroller and radio module of the robot are initially programmed with firmwares that together support Bluetooth communication. Both USB and Bluetooth communication channels use the same protocol called advanced sercom v2, refer to section Communication protocol: BT and USB for detailed information about this protocol. Once you tested the connection with the robot and the computer, you can start developing your own application by looking at the details behind the communication protocol.

Section PC interface gives step by step instructions on how to connect the robot with the computer via USB. When you want to interact with the robot from the computer you need to place the selector in position 8 to work with USB.
WiFi: download the radio module wifi firmware (25.02.19) and then refer to section radio module firmware update.Bluetooth: refer to section radio module firmware update.
The radio module can be programmed with either the Bluetooth or the WiFi firmware, both are compatible with USB communication: If the main microcontroller isn't programmed with the factory firmware or if you want to be sure to have the last firmware on the robot, you need to program it with the last factory firmware by referring to section main microcontroller firmware update. The main microcontroller is initially programmed with a firmware that support USB communication.
This section explains how to configure the robot based on the communication channel you will use for your developments, thus you need to read only one of the following sections, but it would be better if you spend a bit of time reading them all in order to have a full understanding of the available configurations.
