This interface option is directly compatible with Robotis Dynamixel AX, MX series of servos. It can also connect to XL and XM series of servos provided you create a necessary adapter cable or board to connect them. | This interface option is directly compatible with Robotis Dynamixel AX, MX series of servos.

By default the firmware is configured to expose the Console over Bluetooth. This means that control using the Dynamixel protocol is not enabled by default on the Bluetooth port (although it can be enabled if required).\\ | By default the firmware is configured to expose the Console over Bluetooth.
