##Description

# XbeeMav
|
||||
## Description
|
||||
|
||||
The "xbee_ros_node" package provides many tools (ROS nodes) to configure, test and communicate Xbee devices.
|
||||
Four nodes are provided in the package:
|
||||
* config
|
||||
* xbee_config
|
||||
* xbee_mav
|
||||
* test_controller
|
||||
* test_buzz
|
||||
|
||||
The "test_controller" and the "test_buzz" are dummy nodes. They are used only for testing purposes. The "config" node is used to configure the Xbees. The "xbee_mav" is used to communicates between Xbee devices in different modes (e.g. SOLO and SWARM).

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.

|

## ROS services
|
||||
The node xbee_mav provides a ROS service xbee_status that will return information
|
||||
about the xbee module. The information returned depends on the argument passed to
|
||||
the service (example: rosservice call /xbee_status "param_id: 'ARGUMENT'"). The different arguments that can be passed are described below:
|
||||
* id : Returns the xbee module short identifier.
|
||||
* deque_full : returns 1 if the out messages queue is full and 0 otherwise
|
||||
* rssi : Returns the average Received Signal Strength Indicator (RSSI). This RSSI value could be inaccurate since the average is obtained by getting the RSSI of the last message at a fixed frequency without any information about the sender.
|
||||
* trig_rssi_api_avg : Triggers a link testing procedure to obtain the RSSI with all the known nodes in the network. Returns false if there is no other node connected to the network.
|
||||
* trig_rssi_api_ID (where ID should be replaced by a number): Triggers a link testing procedure to obtain the RSSI with the corresponding ID. Returns false if the node is not present on the network.
|
||||
* get_rssi_api_avg : Returns the average of the average RSSI results of the link testing procedures.
|
||||
* get_rssi_api_ID (where ID should be replaced by a number): Returns the average RSSI result of the link testing procedure.
|
||||
* pl_raw_avg : Returns the average of the raw packet loss value among the connected nodes. Returns false if there is no other node connected to the network.
|
||||
* pl_raw_ID (where ID should be replaced by a number): Returns the raw packet loss value between this node and the node ID. Returns false if the node is not present on the network.
|
||||
* pl_filter_avg : same thing as pl_raw_avg but for the filtered value.
|
||||
* pl_filter_ID (where ID should be replaced by a number): same thing as pl_raw_ID but for the filtered value.
