Each drone is running a dummy flight controller node "test_controller". According to the drone type Master/Slave, the "test_controller" node will respectively send or receive and display a command. The commands in the Master drone will be introduced with the keyboard. When a command is received in the Slave drone, it will be printed on the screen. The following table (**Table.2**) depicts the keys of each command: Each drone is running a dummy flight controller node "test_controller".

The communication between both drones is performed with Xbees. The “xbee_mav” node (**Fig.2**) will handle all communications with other ROS nodes (test_controller(Flight Controller) or test_buzz (ROS Buzz)) and the connected Xbee device. Therefore, both Xbees must be configured for Digi-Mesh with the maximum baud rate (230400). The communication between both drones is performed with Xbees.
